Evo's mic sux, record from line-in?

Recorded audio using built-in Voice Recorder. It's simple to use, UI is nice, and it does the job. The problem - quality is simply horrible.
Is there any way to use the 3.5mm audio jack as line-in? May it be for use with external mic or a direct line from a mixer, doesn't matter, could we record audio using it instead? Possible? Just a dream?
Thanks for the help
ps: I need to record various parties, club nights, seminars, and occasionally church services... quality is important.

I don't think it has anything to do with the microphone. I think it is the poor choice of codec that HTC is using for the voice recorder and camcorder.
If you think about it, the microphone is generally one of the best and most well understood components on a phone. They are usually quite good.

You can't record using a headphone jack.

Why not? You can use it for a mic when using a hands-free headset.

semi-related question, can the evo work with the iphone earbud/mic? Would be really useful if it does, I can't stand bluetooth, its a buggy unstable battery draining technology, i much prefer the standard earbud and mic.

I don't know for sure, but I would say yes. My girlfriend had an iphone when I had my Hero and it worked with the Hero.

You know what? You got me. That was a serious "duh." moment - I'd completely forgotten that it's wired to be used as part of a headset. I should probably go to bed.

I was thinking along the same lines - I assumed that headphone/mic combos that go into 3.5mm worked on Evo (didn't try it myself, but some say it works so I'll take their word), so I wanted to use ONLY the mic portion and route audio input through there, hopefully in stereo.
Anyone here has done such feat?

[Q] Any audio recording enthusiasts using EVO's!

Hey fellow EVO's!
I'm looking for a solution to the poor audio quality when recording in a high volume setting (concerts, jam sessions) when using the internal microphone.
Yes, I know that it is not the phone's main use as a personal recorder for this sort of scenarios, but as we all know, the iPhone does it a lot better and I'd really like to show up the iPhone geeks if possible by using an external mic with a recording app.
There's this multifunction audio cable from HTC that I've been thinking about buying and it's called an HTC YC A300 Multifunction audio cable. You can find it on Amazon.com
Any experience, creative ideas, development or anything of that sort that would help me out would be great as I'm sure other people would be able to benefit from the info as well!
Thanks in advance...

I haven't done it, but there is a microphone input in the headphone jack -- it's intended to support a wired headset. With the right cable you should be able to use an external mic.

The app Tape Machine records uncompressed wav files. Even with the internal microphone, it actually makes very decent recordings.

Thanks for the reply guys.
Do you think trying a Sony ECM DS30P might work? it's a direct connection compressor microphone.
I will definitely check out Tape machine. I've got the lite version now and i'm eager to try it now! Is it successful in loud environments?

It's better than the built in mic of the phone. Far, far from decent though.

That completely depends on the quality of the microphone, and how sensitive it is.

Well, I just bought myself one of those nifty little Sony compressor mics and I'm going to see how that works out. I may need a convertor to go in to the headphone jack so it recognizes the input, but I'm not sure.
Another way you could go possibly would be to us one of those multifunction cable things. The model is called: HTC P6300 Multifunction Audio Cable YC A200. There's also a YC A300 as well but I'm not sure of the difference between the two is besides the size.
Any new findings?

So i got that sony mic and a convertor so the phone thinks i'm using a headset...and with some apps, with the convertor it works and some, without, it works too. The only issue i'm having is that the internal mic is still on and working while recording. I want the external mic that I'm plugging in to be the ONLY mic it's using and I'd like to control the input volume.
Any insight as to how we could do that?

I have been looking for a solution to this for over a year. It really sucks that everything else about the device is great except this one feature. As for the iPhone, it sounds like Apple has utilized some kind of filter to reduce the bass the phone records (in my experience, the bass is what causes the distortion in the recording).
If Apple can do it, why can't HTC? :?

[Q] Audio distortion when recording video?

So I've just had my S3 for one month, but I've recently noticed that videos I've recorded with this device have some distortion in the audio. I'm not talking about concert videos where obviously the volume is so loud. Just normal everyday videos.
For example in several videos where people are a reasonable distance (several feet) from the phone, it seems like the audio input gain is so high that the speakers on my earphones are distorted sometimes while people are speaking. In comparison, I don't have this problem when listening to videos recorded with my old S2.
Anyone have the same issue?

What ROM are you running (If any)? It could be coming from it or even from kernel.
Also, do you have any apps that have control over your mic?

Running the stock JB update from Bell, but rooted. I don't think I have any apps that interfere with the mic. Even with volume at 1 or 2, you can notice the problem. However, it's only obvious with the earphones on.

No, because as I said the S2 videos were fine, and I use these earphones all the time for music (sometimes played loud). I wonder if it's a mic issue with my device or a general issue with the S3.

Ah ok, didn't know you tried earphones on both. My guess is your mic, I never had that issue personally nor have I seen it around here.
I wonder if there's a way to control the mic's strenght, perhaps that could help yours if you don't wanna either replace the mic or go for warranty.

I can't take it to warranty as I bought it secondhand (the guy is unreachable now) and I'm on Rogers but with a Bell-purchased phone.
I just tried with another set of earphones and notice the same distorting effect. I notice the problem mostly takes place in the left speaker.. Hmm.. I wonder if it has anything to do with the placement of my thumb and the proximity of the left mic when recording. I'll have to do some more testing when I get home.

SGSIII External Microphone - Suggestions?

So I've gone to several concerts with my Samsung Galaxy S3 and I've noticed... Every single video recording with the stock app is absolutely terribad. The video portion is okay (Great for a smartphone) but the audio is absolutely horrendous. I've lately been wanting to find an external microphone that could possibly connect via the 3.5mm jack and serve as the primary mic for picking up sound.
I've scoured the Interwebs for little success on a good external mic that fit my needs. Here are my findings - correct me if I'm wrong in an area:
1. The mic, in order to be recognized by the SGS3 as a mic, needs to have an impedance of over 1000 omegas and has a TRRS 3.5mm jack.
2. There are actually very few compatible mics that would work with the SGS3. One example is the Edutige ESM 01O, which is overpriced and the specs and reviews do not show that it's a good live music recorder.
3. All other vaguely compatible mics are also not good at recording live music, especially bass heavy music (Which is what I frequent). The compatible lavalier mic I found is not what I need.
4. I actually found a mic that is designed for recording live music - the Edutige EIM-004 - BUT it's not compatible with the SGS3, to my dismay. It also costs $80.
So here's my problem - I need a good external microphone that's compatible with my SGS3 that is capable of recording live music with little distortion. Preferably, I'd like a low cost (Ballpark of $20-$50)I've already got the software covered, there are a few apps that I've looked up that fit my needs.
Here's my phone specs:
AT&T Samsung Galaxy SIII i747 running Cyanogen Mod 10.0.0
I'd really appreciate any help. Posting here is probably the last thing I can try, considering how there's almost nothing out there to help me resolve my situation. Thanks guys.

I really need an answer, guys. Above & Beyond is coming to town in a few days and I'd really like to record them with my SGS3.

I'm also interested. :good:

I'm still looking for a solution myself as I also do concerts recording with my S3. The audio recording sounds much better when you aren't as close up to the speakers. I know it would also help if we could block some of the sound coming in. Like ear plugs to block some of the dB.

I've heard of a few apps that reduced the mic's gain and applied a few filters to clean up the sound, but I don't know how much the sound quality improves.

http://www.parts-express.com/pe/showdetl.cfm?partnumber=390-810
Here's a calibration mic might work.

I like this mic, David. The only problem is the impedance. The mic is 200 ohms but the SGS3 needs a mic of at least 1000 ohms in order for the mic to be recognized as a mic. Otherwise it'll only be recognized as a headset.

For concert recording try the negative mic gain in Boeffla kernel.
I9300XXEMD3, Boeffla 2.12, Earsonics SM3v2

i know this isnt going to help much, but i simply cover the mic's slightly with my hands. when i have my phone in the air recording something, phone horizontal, i place my hands in front of the mic holes, so it only records sound from behind my hands. this helps ALOT.
and what do you know...i'm also an A&B fan. recorded last weekend with the above trick:

Nice! Hope you had a good time at the show haha. I think this is going to be my temporary fix to the problem (Considering how A&B is coming to town tomorrow I've lost all hope of finding a mic in time), but I'll still need a solution for when I go to Ultra... Because their Funktion One systems are definitely too powerful for this fix.

A quick answer for yah Mecronmancer.
- otg usb cable (couple of bucks)
- Digital to Analogue converter with USB (Appr $30) Behringer UCA222 is what I have.
- USB recording app...USB Audio Record or Audio Evolution. Both apps from Same guys.
- Microphone or analogue stereo inputs (Sky is the limit here)
- a rom that supports this arrangement. My i747m S3 with Stock ICS 4.0.4 works flawlessly with this arrangement.
You will get 16bit, 44.1k Stereo recording quality. Will it record while another app is recording Video? That I don't know. Thiis may be your one caveat. I might give it a shot sometime this week and report back.
UPDATE:
I simultaneously recorded USB Audio with the USB audio app and Video+mic audio with the built in ICS video app successfully. So if it was me, I would combine the 2 source recordings using a PC app and have HQ audio with Video. You just need to time align the 2 in sync very easily since you would have lofi mic audio and hifi usb audio sources.

@guy48065
The UCA222 can be powered from your Smart Phone, in my case, the SGS3. I had to buy a female-A-USB-to-Male-micro USB plug. They are inexpensive. I can't remember if this cable had to be an OTA version. (On The Go)
In my car, if my memory serves me well, I had the USB split with one end going to the SGS3 and the other into my USB cigarette lighter charger. I didn't end up using it in my car because it didn't interact well with the phone call audio stream etc. Lots of glitching.
RE-Recording Sound Quality
Unless your a professional audiophile or sound engineer with impeccable trained ears, the recording quality is flawless and blows away what I could do without it. An app like Audio Evolution Mobile is a great combo, especially if you have a larger and fast tablet.

Ok so it doesn't get power from the phone and it has no batteries. Darn. ..I was hoping it could be a handy mobile recorder.
A splitter usb + battery supply is borderline too cumbersome.
Price is great though -- I might tinker with it as a means to dub vinyl to files.
Does anyone make a $30 adc that includes a phono preamp? Lol.

I didn't think phones were capable if supplying usb power so when you wrote about the OTG cable *and* the splitter with power I assumed you needed both.

[REQ] Enable Dual Speakers

On my old phone, Galaxy S5, there was a small mod that enable dual speakers and it totally made the experience better. So, can somebody figure out how to enable dual speakers on the LG G4? I know it has to be in mixer_paths.xml, but I don't know what lines to edit

Just out of curiosity what do you need it for? Audio play back or phone call? Seems like an interesting request as the ear piece probably cannot put off good loud sound without peaking.

Doing this mod is very dumb in my opinion. The earpiece speaker on the phones is put at certain cut of sound frequencies in order to focus in the voices and not so much background noises. So in order to having it be a speaker will not sound so good at all plus also the risk of blowing it will be much greater for it isnt meant for audio other than for phonecalls for it also is much smaller than the dedicated speaker for music.

I don't listen to very high volume on the G4 speaker at all, and I also use speaker optimization in V4A. I really like the the stereo effect this would probably give if the ear piece got enabled. I loved this very much on my Galaxy S5 and I can respect your opinion.

I'm right there with you! I had this mod on my G3 as well. Loved the surround effect. If the mixer path is edited properly (balancing the earpiece at a lower level compared to the rear speaker) no damage and great sound effect. Unfortunately as much as I have tried, the G4 mixer path xml is a nightmare to navigate, I've tried countless times to obtain this surround effect using the previous device mod as a guide, but no dice. Best I could do was gaining a respectable volume increase in call and speaker output without getting into distortion territory. Love the G4 but some of the new files are quite the pain!!!

Very true! After seeing the G4's mixer_paths.xml in my file browser, my eyes were twitching! I have no idea where to start editing so I was hoping the fabulous XDA G4 community could help, but at this point all I'm getting is: "your gonna blow out your speakers" or "this is dumb". But at the same time I can see where they're coming from, there's a chance the speaker(s) can blow or this mod may not be worth fighting for.

I had the HTC Boombass as a free promo when I got my HTC One M8. It was set up to provide bass over and above the normal HTC M8 speakers and worked quite well. That kinda falls in line with what you are saying about the earpiece, it could be used to add a little something without trying to equal the loudspeaker in range or volume but could still prove useful to the overall sound.

Had a mod like this on my Nexus 5 as well. Tweaked properly it can sound great.

there is actually a thread where a stereo mod is published, also is installable with(or without) magisk
