[Q] earphone over external speaker, is it possible? - One (M8) Q&A, Help & Troubleshooting

I tried to do a search for headphones over the speaker but didn't come up with anything, so...if a thread like this is already out there please point in right direction and delete then. Alrighty on to the question.
When you plug your earphones into the phone you get to listen to some radio(FM) but you also have the option to play the FM radio over the speaker itself, which is awesome. Now I want to know IF something like that is possible for youtube as well? I can't see anything that can enable me to choose the speaker itself(like with FM radio) and instead forces me to listen to it over the earphones.
Is there an option like that and if so, where?
Yes, I'm well aware that this might seem like a completely stupid question, but at any given time someone has to be the idiot that asks it :victory:

I don't understand why this option would need to exist. Headphones need to be plugged in for FM radio to work because they act as the antenna, which is why you get the option to use the speaker, alternatively. YouTube doesn't need an FM antenna, so just unplug your headphones if you want to use the speakers.

Because the audio is louder... Have you tried to listen to a radio station through FM on the speaker and then go and listen to a stream of it at full volume? Somehow it seems that the volume can go higher with the earphones plugged in than to have it NOT plugged in. Yet...It could perhaps be argued that the stream sounds less loud(regardless of the fact that the volume is maxed out) because it is indeed a stream and it might have some interference.
But if the volume can actually go higher as a result of the earphones being plugged in, why can't we have the option then to have the volume louder if we so choose, by plugging in the earphones and maxing out the volume over the speaker? Like we do with FM...?
I take it though, from your response, that such a thing is not possible?

Ahh, I think I'm starting to follow. There are a number of factors that are likely causing this differentiation, none of which have to do with having headphones plugged in.
A radio station's FM broadcast and internet broadcast are processed and compressed in different ways. FM compression is analog, while internet compression is digital, and there are crazy different algorithms, but both come down to fitting the "signal" or "data" into a particular bandwidth.
With FM, a station just throws the signal out in all directions, and while it's technically not comparable, there is less need for compression here, as with the internet broadcast, the more listeners there are, the more taxing it is, thus the digital signal is likely more compressed. This is probably more or less the reason for the discrepancy.
Also the streams could be normalized differently. Or any number of other variables. For all intents and purposes, the FM stream and internet stream are two completely different things.
I hope this helped!
(And no, as far as I know there's no option to do what you want, but even if there were, it wouldn't have the effect you're looking for )

Why would compression affect volume? It's not like you need more bits to go louder.

FM audio doesn't have bits, for starters, it's analog radio waves. Functionally, an FM broadcast path is analog to analog to analog, where as a digital broadcast path is closer to "analog to digital to analog."
And from a technical standpoint, yes, more bits *does* equal louder. The more you compress digital audio, the more audio is being removed from the stream. MP3 compression (and probably M4A/AAC) remove the high-end and low-end frequencies:
In a compressionless, raw, audio file, a ton of bits are wasted on sound that is beyond the range of human hearing, and the range that speakers can produce. The point of digital audio compression is to eliminate the functionally "empty" bits, however the more compression there is, the more it starts removing what humans/speakers CAN process. As you approach high compression, mp3s will lose more and more sound, but even with mild compression, you're going to lose the crispness of the highs (like cymbals) and the lows (bass guitars/synths.) This will give it a muddy sound, and as there are less cymbals and bass guitars, the sound is technically quieter. In fact, if you were to compress an mp3 down to like 1Kbps, it's going to mostly sound like static. But I'm not aware of any audio tools that will let you go that low. Online radio stations typically broadcast at 64Kbps or 96Kbps. Which is crap. (Of course I haven't listened to online radio in years, it's probably better by now.) To put it another way, an FM transmission can broadcast at full strength, whether one person is listening or a million. With a digital broadcast, one million listeners will be far more taxing on bandwidth than just one person listening, so it's not cost-effective to broadcast with the same signal quality as FM. Of course FM is subject to radio interference, but that's not selective the way digital is. On FM you'll hear other noises on top of the signal, but as long as your signal is relatively decent, you're not losing much.
Without teaching a course on audio processing, basically:
More processing = more degradation.
More compression = more degradation
Analog is very different than digital for a multitude of reasons that I'm not going into.
EDIT: Also, FM does use compression, but it's a different type. Rather than removing audio based on pitch frequency as digital compression does, it uses dynamic compression, more akin to what a guitarist's compression pedal would do. It makes the quiet noises louder and the loud noises quieter, definitely makes quiet songs louder than if you were listening to an mp3, which doesn't do this type of compression.
ANOTHER EDIT: Unless the topic steers back towards mobile development, I won't indulge this thread anymore. XDA isn't for audio discussions (yes, I know I'm the one who took it off the rails in the first place.) If anyone is still confused as to why FM audio and digital audio sound different, you can PM me.

FM radio volume mod possible?

Hi guys, I've always notice serious volume issues with the FM radio for the desire. I was hoping on 2.2 sense it would be resolved but sadly it has not.
Its really strange the music player volume is great at max volume its to loud if anything, yet on the FM radio at max volume I cant walk by a road and hear it clearly over the noise of just the passing cars.
I was sat on a but and trying to listen to the radio 1 this morning in the UK and I couldn't make out the speech over the noise of the engine. I ended up swapping to the music player be cause it was the same on all the radio stations.
So does any one know if its possible some how to mod the FM radio to increase its volume?
As far as I know the FM volume is tied to the signal strength.
So it means that if the signal is low and/or the antenna is bad the volume and quality is bad.
The Desire like most other phones use the 3.5mm jack cord as antenna.
I'm not sure if this will work... but try adding an extension cord to the headphone jack.
Or try moving the cord to a better position, like you adjust a old TV antenna for better reception.
Its strange though I've tried that with little effect, when I've been testing the signal indicators are always at max, and other radio's get very good reception in the area. So I don't think this really is a antenna issue.
It could just be my phone, I don't know if its a fault but if say I had the same song playing on the FM radio and then listened to the same song via the stock music player both with the volume set to max the volume of the stock player would be at least double that of the the FM radio.
I was wondering more if there was some form of amplification/gain mod possible. Just like how there were kernel mods to increase the volume of the standard media player. I tried these at the time and stock player was louder but the FM radio didn't change, so im guessing the FM radio application does not follow those gain settings. It may not be possible because I think what could be needed is modification of the FM radio binaries which I think are closed source.
Any solution to this issue? I am having the very same problem one year later on my Desire S.

I've discovered that many of the Qualcomm SOCs contain a PGA (Programmable Gain Amplifier) on the Aux/Line In ports commonly used for FM analog audio.
Sometimes the default gain is too low, or too high for FM. One device was too loud on FM so I added a Volume Scale setting to my FM app. But that only reduces volume (from the FM chip) and can't be used to raise it.
There are some Ioctls or whatever on at least some devices that could be used to change the gain. So it's possible... I may look more deeply into this at some point.

Mangler+mic= McD's telecom

i downloaded mangler from the market and joined my friends ventrilo server which is pretty cool.
one thing thats annoying me to hell is the sound quality. im using the klipsch s2m with mic and they said i sound like the mcd's person and kept on saying "would you like fries with that?" lol
i tried with the headsets mic first, then the phones mic and then other sets but they all sound the same. also did with wifi and 3g no difference.
any idea why its like that? is it the codec thats really crappy on the phone or the mangler app? i logged on vent through pc and phone and listened to it. it sounds just as bad if not worse than the recorded video
I don't think any of us have tested it with a wired mic/headset. We're not really that far in yet. However, have you tried with and without "force 8khz" option?
yep. tried both. tried every option available
And I assume it works fine without the headset. If so, you'll just have to wait until we get around to testing with the wired mic.
And just FYI, BlueTooth is impossible because it's not supported in Android (via the public API)
sorry for late reply. its still the same without the headset tho. with inline mic and with phones mic i still sound the same. i tried another vent app called ventriloid and i do sound a little bit better but the robotic sound is still there.
could it be the codecs?
im trying to figure out also if there is a fix for the recording audio as well.. like an external mic but everything i have found said that it doesnt work
Could it be some setting on your vent server? Or maybe you have a bad/high-latent 3G connection?
I've used the built-in mic a lot with Mangler, and the audio is just fine (even tested this myself by logging into Vent on my PC at the same time).
I'm going to go out on a limb, and guess that it's the codec or your connection. The app might be auto-compressing your audio because it thinks you have low upstream bandwidth.
Also, are you by chance using a Froyo ROM? The AAC+ decoder is crap in it, so it's not a stretch to imagine that the encoder is also crap, and since AAC+ is such an efficient codec by bandwidth, it's easy to see why it would be chosen...

Calling all audiophiles, voice your preference!

Since I've found Voodoo Sound, I've been aware of alternatives, such as PowerAmp. I never did try PowerAmp today, I must say, it does seem to blow Voodoo Sound of the water, not sure if this is just because of the equalizer, or if Voodoo is still a better option, or if its best to have both on.
As I understand it, PowerAmp is just offering a software optimized equalizer giving you that nice virtual experience of good quality music, while Voodoo Sound is supposedly tapping out the potential of the Wolfson Sound's Hardware.
Opinions and clarifications are much appreciated, do share if you know of something better, just spill your thoughts.
Feel free to include the Rom you prefer for music, the apk you prefer fo music, and what tweaks you're using for music, as well as the earphones/headphones you listen in with.
I'm setup this way:
Rom: CM9 Beta 1
Music Apk: Usually Stock CM9 Music, with DSP Manager uninstalled, atm trying PowerAmp though.
Tweaks: I have Voodoo Sound Plus, trying to listen to music with PowerAmp and Voodoo Sound on.
Listening through: In-ear Phones, Sennheiser CX300's.
Edit: *Disclaimer!* this is probably my third thread this year that is a semi-question asking for your opinions as well as general discussion.
To be on the safe side, I posted in Q&A to avoid getting *****ed at.

If it's really necessary to have both voodoo control and poweramp or of using both is an overkill, also looking for what others are setup, maybe things they've discovered on each to be better or worse, and what headphone earphones they use.
Hence the title, "voice your preference."

its defiantly not an overkill it a helper to make better haha. But Running CM7 and using the Klipsch S4
Did you need to quote the op?.. no... its a given that your answering about the OP just sayin.
I'm not quite an audiophile but do enjoy my clear a crisp music. I'm running cm9b1 with my compiled samurai kernel. I use voodoo sound and have my amplifier "deal" at -5 instead of 10 and on bass boost I have it on standard with the db at 8 and the range at 80%.
I also use equalizer off the market have the paid version so I have one of my profiles in a V the left starts towards the top the 2nd is towards the middle and the middle is just shy of the bottom and the last two are similar to the first two if you catch my drift... it makes a V . Have the same deal on my laptop with beats audio the control is setup in a v like design... seems to be a sweet spot to me. Or at least my ears... I listen to a lot of metalcore.. usually their "screams" or dirty vocals aren't very clear but with setup I can hear it all.. with comprehension.
Oh and I have some 17$ phillips and they sound great.. =] have lasted me almost a year now... much longer than ANY headphones I've ever owned.. usually the part by the jack wears/ shorts out and its time for new ones.... not with these.

What you need to understand is that Voodoo Sound Control increases power to the device's built in hardware amplifier. This is where it's at. If you can't tell the sound quality difference between the software and hardware amplifiers, you probably shouldn't even use something like Voodoo Sound Control.
The Galaxy S models are among few devices available that have a configurable hardware amplifier. Typically, the volume rockers on phones control the software amplifier, while the hardware amplifier is locked to a single output. This is probably due to output limitations determined by the manufacturer in order avoid lawsuits involving inner ear damage, in the event of an immediate volume change (we're all familiar with Android's rather mediocre sound control quirks due to hardware fragmentation).
Try this:
- Disable Voodoo sound or set it back to default system values, and disable all sound modifications.
- Plug your phone into your car stereo or home speaker system with the 1/8" jack, and crank the volume on your phone all the way up, using Android's system media volume.
- Then, crank up your stereo. It probably sounds like balls.
Okay, now let's experiment with the hardware amplifier.
- Now back the media volume down a few notches to around 80%.
- Increase Voodoo Sound's amplifier controls to +2db or so, enable Hi-fi play, etc. Keep the media volume at around 80%.
- Turn up the volume on your stereo system again. I will be absolutely damned if you don't notice a difference.
PowerAmp's "pre amp" is just an additional software amplifier "boost." Although handy for increasing the volume on particularly quiet MP3 files, it will cause distortion in the same way any software amplifier will. If anything, you will want to lower "pre amp" a tad if you plan to increase the Android media volume to 100%, but in the end, the resulting distortion will always be proportional the the volume.
Props to the developer for Voodoo Sound. It really changed the way I listen to music. Before I buy my next device, I am going to make sure it will eventually be compatible with Voodoo Sound Control.

This. So much. Thank you for this educated post.
Hardware amplifier > software amplifier.

I rely on voodoo sound to maximize my overall hardware output, especially getting that lower level ooompf that the phone generally lacks.
This is especially helpful when using a music player without any sound control- most notably Pandora.
Poweramp is my preferred mp3 player app, and has some nice tweaks I can make when I need to- like if a particular mp3 sounds dull I can turn the tone on or adjust the octaves. Overall I usually have the preamp turned up just to get more volume out of the device.
Definitely Max out voodoo. never completely Max out the phone's volume level, doing so causes distortion.

Of course your going to get a ton of different opinions in this thread, everyones ears hear things different, so instead of arguing or denying what other people hear, I'll just give you my 2 cents.
I use Voodoo AND Poweramp together through a pretty cheap set of Skullcandy Titans listening to predominantly metal/punk/progressive music. Voodoo is mostly used by me to have a more fine tuned volume control, and to reduce/prevent distortion like so many have mentioned earlier. If you notice the stock volume control only has like 9 steps, where Voodoo can go up by 1-2 db at a time. This gives you alot more fine tuning possible with your volume level. I've found stock android steps are either too quiet, or too loud once I bump it a notch...
Oh and then theres the poweramp side, I just have always loved poweramp, even been a fanboy. Since the days of Android Music players where NOBODY had an EQ I've been using it with great success. I've tried the stock music player/EQ, PlayerPro, as well as 5-6 others I've only kept for a day or two, and my ears always take my back to poweramp. Other music players may tout the same features, but to me Poweramp just sounds better to ME personally. My best buddy has the same phone, same rom setup, and prefers Voodoo and stock music player though... again it's just a matter of what your ears like to hear.

Oh no, trust me, I do know what Voodoo Sound does, I did need a post like yours to confirm my speculation on Hardware Amp > Software Amp though. So far, after reading everyone's replies, I think I'm going to definitely continue to primarily use Voodoo Sound, and use an equalizer off the market, or poweramp's equalizer. Thank you all for taking the time to voice your setups and preferences. Much appreciated!

ISO app that can record audio like a boom box with cassette recorder built in.

Here's what I'm trying to accomplish. I am looking for an app that will record any audio being played, but not record it with the phone's microphone. If you have ever had a portable stereo with built in cassette that records, then that is the kind of app I'm looking for. An app that can record digital "mix tapes". I could just use a patch cable from the headphone out of the phone into line in on the computer then use audio recording program to do it too. That idea isn't really portable enough. I would like to record, in a format I can actually do something with in an audio editor, streaming music, news, shows, scanner radio feeds, etc. The few recorder programs and mixer apps only seem to use the mic to record everything.
Tunein radio pro records but you can't use the raw files it creates for songs.
Any suggestions?
Why
First is there any specific thing you are trying to record? Phone calls, pandora music, youtube, music player, etc. If so there are other known ways to capture that audio much easier.
This guy seems to be working on the same thing: http://xzpeter.org/?p=254
But unless your skilled in Java programming, I would think about what you want this "feature" for.
Lastly, you could dismantle your phone and attach the speaker output to a 3.5mm wired mic and attach that to the phone and get all the audio through a loop. Not sure if that would work and would void warranty. TRY AT YOUR OWN RISK
Why not just buy a digital voice recorder? They are portable and can be connected to the phone. Some have bluetooth too but not sure how they work with bluetooth exactly.

I've got one and am trying that but its not giving good enough results. First, the output of the phone is too hot for the variable input of the dvr. I'm not good at making cables but if I could have a stereo male to male 3.5mm with about 9db of attenuation then I could drive the recorder better. I know its an impedence issue but don't have the ability to do it. Second, whenever you move the phone or dvr, you sometimes get static from the plugs moving.
First reply: I would like to record things like Pandora, tunein radio, stitcher and maybe rdio.

HIFI DAC Help( Audio Experts needed! )

Hi guys. I downloaded an app called Android hidden settings from the play store. I already use settings database editor as well as the hidden settings magisk module, but I saw if one thing inside this app I haven't seen anywhere else. There is a setting called Hi Fi DAC pop up. When you click on it floating window opens and it gives you the option to turn on DTS x and the hi-fi quad DAC. you can toggle the switch is regardless of whether or not you're playing music so I figured this wouldn't do anything. This is what I noticed:
When the floating window first appears, DTS is already enabled, I disabled it and toggled the DAC switch to the on position and proceeded to open my music player. From here I opened the full settings menu and clicked on the sound effects section to check if the DAC was switched on in the phones full menu and the toggle is actually still set to the on position. Figuring there would be no change in sound, I messed with the left and right channels anyway as well as the sound preset and digital filter. Before I go further I forgot to mention that I do not have headphones plugged in, I am playing music directly through the phone speaker. To my surprise, the audio quality does change and the volume is limited to 75 as if a headset was plugged in.
I opened up the Flinger Dump app to check audio output details but it is very limited to what it shows. I'm wondering if anyone with more knowledge on the topic and the proper tools could do some further testing and see what changes actually occur. I use UAPP, and its output is showing differently then flinger dump is. Could be a complete waste of time, could lead to something further...
If I have not misunderstood, what you mean is that with that app, you inadvertently activated the dac or the dts for the speaker's sound channel, right? If so, it would be amazing to be able to modify how the dac behaves without headphones. Perhaps it could be activated for the speaker, perhaps not, but what you propose is very interesting.
I'm honestly not sure. I don't believe so, but it's definitely done something and I don't have the knowledge or the software to see exactly what has changed. Basically, unless you have headphones or an auxiliary cord plugged into the phones Jack, you can't toggle the Hi-Fi DAC button to the on position as I'm sure you're fully aware of. This hidden shortcut allows it to be toggled on without anything plugged in to the headphone jack. I played some tracks thinking that there is a 99.9% chance that the audio quality wouldn't change ( or the sound wouldn't change, I don't know about quality ) but to my surprise it did change the sound. As long as the DTS:X is turned off, all of the other options had some sort of effect on the audio. The sound preset, the digital filter and the left and right channel knobs all had some sort of effect on any audio I played through the phone's internal speaker, and the volume limit changed from 100 down to 75, exactly how it would behave if headphones were plugged in.
I just need someone to help figure out exactly what this is changing, because my music app is showing 16bit and various Khz from the 300 range to over 1000...and as you can see from the screenshot the FlingerDump app is showing 24bit to 32bit and depending on the track but the KHZ remains the same.
It may be a dead end, but I figured that since there is an actual change in sound.... there may be a possibility for someone with more knowledge than me to take this and run with it and see where it leads. I removed all of my audio mods except for JamesDSP and John Fawkes DTS tuning because every other mod made my phone upsample everything from 44.1 to 48 and it was pissing me off. The results above were with USB Audio Player Pro, but I disabled bit perfect mode when I tested this out in order to avoid interference with the results.
I'm on stock android q (through fota) and out of curiosity i tried that. Nothing happened. I can tap it and nothing. The same with dts settings. Turning quad dac to small speaker for me have no sense. Idk how circuits looks, but i think system itself don't let reroute signal through dac to speaker. BUT if ypu want to check then try that.
Open terminal app and type
su -c tinymix
And look for what is on screen.
If it's state is closed then quad dac is not working. If state is hifi, then it's working.
