[Q] Evo sound quality is fine, but loudness?

I swear before I ever rooted, my phone was much louder, am I just quickly loosing my hearing? or am I not the only one who has experienced an across the board loss of speaker loudness?
(*I HAVE applied the pandora streaming quality fix*)
and it did help considerably, but its just not as loud with any application! streaming or not.
what can I do.

Rooting by itself wouldn't have any effect on sound quality or volume. If you are using a custom ROM or kernel, it might though... and you didn't specify if that's the case or not.
However, your sig says your are on CM6. I haven't played with it myself, but there is supposed to be a DSP in the Audio settings now for CM6... perhaps when you installed the build it enabled the DSP and set everything low?

[Q] MP3 sound quality issue

It could just be my phone, but has anyone noticed their music sounding like it have really really small breaks in the sound, almost like the music is crackling? I've even found this when listening to my Sirius Satellite Radio app.
Though I may have found a fix, at least for the music. Originally my music was 320bit and i had just copied a few songs to my GN. When I started to listen to the music i would get crackling like sound or where the music would have almost a stuttering factor. Well i was getting annoyed enough with the crackling I almost went back to my MP3 player. Though I decided to try it one last time but i wanted my entire playlist. Now my playlist was about 200 songs and across many directories so I wasn't going to try search the whole thing for individual songs. Using winamp I copied them all into one directory, unfortunately when Winamp does this it converts them all back down to wav files so I had to reconvert them.
My software for converting back to MP3 is older and only able to convert up to 256bit. I was thinking it was going to be just as annoying, but low and behold my music plays without a glitch, or crackle or break or what ever.
It's almost like the phone can't handle the higher quality of music. Now again this could just be me so I thought I would ask. Unfortunately my Sirius Satellite Radio app still crackles.
Anyone else find this?

also if u have used an app like volume+ to increase your speaker volume, or modify your volume that could be the issue

Good thought, though i never actually got around to installing the app so we can eliminate that as a cause.

Oh no, lossy to lossy transcoding! Those poor files.
I haven't had any issues playing 320kbps MP3 CBR or MP3 V0. If anything they sound better than on my old iPhone 3GS, especially with DSPManager.
Do they play without any distortion on your PC? Are you using the same headphones?
Perhaps playing around with the equaliser settings in DSPManager would improve the output.

Have had the same problem but only with one album so far, it is 320bit but I also have other albums at 320bits that play ok. Strangely the problem doesn't occur if the screen is on!

Give me to this weekend and let me hoot the phone up to my input on my PC maybe i can let you all hear what I hear.

I would agree too if I had actually installed volume+

I don't think it's to do with the bit rate as such but the encoder, or at least the encoding settings, that you used. Almost all my mp3 are in 320 kbps, CBR and VBR, and they all play fine.

the phone seems to clip a lot when the volume is at the top two levels. sounds bad. setting it to 3rd highest level or less makes it sound normal and smooth

Not sure if they fixed this with 4.0.3 yet, but it's a known issue that any SAMPLE RATE (not bit rate) other than 44.1KHz can cause stuttering when the phone is in screen-off low power mode. Some EQs that cause the cpu to work have been known to fix it. Also changing the buffer size in PowerAmp has also I think. There are a few threads about it. I have recreated it with another persons 48KHz sample rate mp3. All mine are 44.1KHz and I've never had a problem with any of them, they all sound fantastic.

Maximize Bluetooth Bandwith on S3 i747?

I have been searching around and I can't seem to find the answer. Is there a way to insure that the bandwidth on the Bluetooth audio connection is maximized?
I listen to lossless audio in my car (3 way active system) and I want to make sure the Bluetooth configuration is not throttling down the audio quality. I have seen where some developers of the other phones have messed with the settings within Android, but I couldn't find anything on the i747.
Thanks

Great question! I'm running CM10 night lies and the BT streaming quality is horrible. It sounds like the audio stream is compressed . I've tried several different music players as well as a EQ apps but nothing seems to fix the tinny sound

Same here, Bluetooth A2DP audio in CM10 is quite compressed.

The bluetooth quality on AOKP is TERRIBLE. Sounds like it's coming out of a speaker I made in grade 11 physics class. (
Anyone found a fix yet?? Even increasing the Bluetooth MHZ in KTweaker yields no results.

DAC Fix - Use the HI-FI DAC Everywhere!

Hi everyone! I've just developed an app that should fix the issue of the DAC only being usable in some apps.
Now the ESS DAC/AMP can be used in any app on your phone, including Google Play Music, YouTube, Spotify, and probably many more that I haven't tested yet.
Here's the Play Store link: https://play.google.com/store/apps/details?id=com.phascinate.lgv10.dacfix
It can be set to automatically turn on when the phone boots up. My goal was to make this a "set it and forget it" kind of fix. All you have to do is enable it once, and it should be fixed for good. Of course, I've only just released it so it may have some bugs. But so far it's working fine on my end.
If you have any issues or it's not working correctly, feel free to tell me here! Hope it works for you guys! I'm really loving the sound quality on this phone.

doing back up now so I can try this, very exciting news if this works
Seems like it's working in Neutron amp which has been my pain point ever since buying the phone.
Thanks!
*tested with youtube and DI.fm both seem working with the DAC with the fix

wow big deal, thanks

Tested with YouTube and XiiaLive Pro and the volume definitely changes when toggling the hifi option on and off.

It is working on Poweramp. Thanks.

Interesting... Can the developer tell us a little more about how this works? I really didn't think it would be as simple as an app like this making it work.

The concept is actually quite simple! Immediately when music starts playing, it plays some completely (and I mean completely! We don't want any background noise, do we?) silent media which tricks the phone into turning the DAC on.

Assuming things were bit perfect to begin with, will the signal still be bit perfect?

In theory, it should be. Because it's set to be silent, Android should simply completely skip over the silent media. In my own testing it doesn't seem to have had any negative effect whatsoever on sound quality. Though I'd love to see the frequency output in something like Audacity if anyone wants to test it.

Alrighty. Right now I'm on my lunch break at work listening with a Brainwavz HM5. Things seem good here, but I'll test tonight with my AKG Q701.
I really only use the stock music app and TIDAL which both worked without your fix, but I'll test everything out more tonight. My only concern would be a possible negative effect with apps that already worked fine, for example a silent track playing along with the regular music making things possibly no longer bit perfect, or extra battery drain for some odd reason. I'll test sound quality with my Q701 tonight and see if I notice any extra battery drain. All I can confirm at the moment is that toggling hifi on and off definitely changed the volume with apps that it didn't before.
Good work.

Yeah, that was my concern too. But everything seems to be working fine.
Feel free to post your results with the Q701's as soon as you test them!

Good job, works as intended. Thanks.
Few suggestions: Show status of app running in background from top pull down menu. Also the ability to enable disable from there. Otherwise still 5 out 5. :thumbup:

man you are a genious and this is the best ever app i appreciated this year

Does this app need root permission?
Edit: nvm. Just installed and gonna test..

Thanks for the effort mate. I'll also give it a try though as a non-audiophile person, I fail to notice Hi-Fi DAC effect anyway.
for those who can distinguish the difference between DAC enabled/disabled, can you tell that's even distinguishable with the QuadBeat headphones? I'm trying with some FLAC and various music players but other than then "higher volume" I cannot notice an improvement sound wise.
I do try with the QuadBeat and Bose QC25. I also just purchased a Piston 3. Do you think it's my headphones who are not enough to make a difference?
Can you maybe recommend a song where you can clearly distinguish the performance between DAC enabled or disabled?

Amazing app, thank you very much.
Now I challenge you to check the other audio limitation of the phone.
The normal and high gain mode of the Amp depending the impedance of the headphones at the moment is completely automatic.
That's OK with IEM but there are problems with big headphones with low impedance. In those cases the normal gain mode delivers not enough power (volume) and being able to select or force the high gain mode would be a perfect solution.
At this moment the high gain mode is triggered with headphones with an Impedance over 50ohm.
Thanks anyway for this app.

Seems to be no negative effects on SQ. Not sure on any change in battery life yet. Good so far.

Fantastic! At first I thought there would be a big battery impact since there is silent media playing, but then I remembered that only happens when there is actually music playing - fantastic implementation. Hopefully there is no battery drain. Works here for Google Play Music, so thank you very much!!!

it is working great with spotify here
I do notice the clarity with dac on and off.. however i'm using free spotify so the music stream is not high quality.
I only did notice a bug not sure because of this app or not but it never happen before.
So today i plug my phone to aux in my car in the morning everything work great.
in the afternoon i plug aux again to my car and this time my 4G or 3G writing on my signal bar is gone until i restart. This never happen before i install your apps, but seems i can't repeat this bug.

Firstly, thank you for taking the time to make this app. I just tested it with Player Pro and it seems to be working (Player Pro did work before but only if you didn't install the DSP pack). I did have one question. I noticed that the EQ is not working in Player Pro. You can open the EQ, but changing any of the frequencies or selecting a preset has no effect on the audio. Does that mean that the other audio features like Replay Gain also won't work with the app installed?

High latency with headphone output

I am beta testing the new Poweramp V3 (alpha3 build-703) and using the Hi-Res Output (24 bit, 192 khz). It sounds really great, 5x better than the standard android API.
But I noticed that when I click "Info", I have 1687ms latency with the output with any earphones plugged in.
That is way too high because Xperia Z5 has 280ms latency over the same output (Pictures below!). Other phones with dac also have lower latency.
When playing music over the speaker, the latency is 100ms (normal).
Can someone please check his HTC 10 and see if he gets the same latency with Hi-Res output in Poweramp v3 ?
When at the song screen, you need to click the visualization icon, and the click the "i" icon to see the info.

I've noticed that as well, having no idea why the latency is >1000ms, even the "now playing" progress bar is going several seconds at a time.
PS: You may want to disable DVC and Headroom Gain(If you don't use equalizer), as when DVC is enabled on htc 10, the amplifier will be maxed out while PowerAMP use DAC to control volume, which will result in far worse signal-to-noise ratio unless you are at 100% volume.

You have 1687ms as well ? I hope that hasn`t got anything to do with hardware.
About the "now playing" progress bar, I have also noticed that, like there is a delay, probably a bug. --> When using the other 2 outputs, there is no delay, and the output latency is normal.

I do use equalizer (rock preset), I thought DVC gives you improved dynamic range, I noticed the sound is a bit better with it...

Latency here 160 ms.
ah, the second one is 1687 ms for me as well on output.
Keep in mind though this release of poweramp is highly unstable on my 10.
There seems to be no response from the poweramp developer, I've tried emailing him and his forum, all no go...

At least it is ~1700ms. Mine is at ~2800ms. Other than that, Poweramp works beautifully...
