[REQ]APP To EQ audio from Camcorder - T-Mobile, Samsung Galaxy SIII

I do a lot of video recordings of acoustic songs. Is there any way to create an app or add-on capable of equalizing the audio from the camcorder? I use a 3.5mm to XLR Jack for recording the audio, but it would be great if there was a way to EQ the audio, so I could just upload to youtube. Any thoughts?

camera audio quality

Is there any way to increase the audio quality when anything is recorded? I am getting 8000 hz. horrible. not sure about the bit rate, but still if that is changed audio would be alot better.
I used to have an iphon (hated it everyday) but when I hacked it and downloaded a video camera program, the picture was horrible the audio was recording at 44100 hz and the bitrate was 705 kbits/sec. only 1 channel but you should hear the audio because wow.
can anything be done with total commander??

[Audio] Comparison, what is available in video (appalling), what is possible

Somebody took the time to make this nice comparison between what is available in video for audio (appalling) and what is possible with the microphone for a N1, but should more or less be the same for the Desire:

This really needs fixing.
That's ridiculous. Anyway, I took four 20 seconds recordings of some of my music, once in HTC Sense camera, once with DeFrost Nexus One camera. They have exactly the same quality, I think, but you judge, they're attached in a zip.

the N1 has dual mic for noise cancellation.
I doubt it has anything to do with the dual mic. If media_settings.xml file is anything to go by, audio in video files is recorded using the amrnd codec, at a quality of 12.2kbps and a sample rate of 8000Hz...
Same on all profiles from the looks of it (720p, low, youtube, etc)
Code:
<AudioEncoderCap name="amrnb" enabled="true"
minBitRate="5525" maxBitRate="12200"
minSampleRate="8000" maxSampleRate="8000"
minChannels="1" maxChannels="1" />
And don't forget the audio settings they said they used for PCM Recorder Lite...
16-bit WAV at 44.1kHz... then converted to MP3 (conversion makes no difference to the initial recorded format, other than compressing it)
Is is purely about the amr audio codec used in video recording.
Why not write out 44.1kHz 16 bit PCM data to the mp4.

[Q] Camera gain control

Is there any way to control audio gain when recording videos? Some scenes such as concerts are way too loud for Nexus thus leading audio on video recordings totatly corrupted and useless.
Some audio recording apps have this option, but I haven't found out yet video recording app with such capabilities.
That would be amazing... My Nexus S records almost perfect audio with the Voodoo Recording Presets...

Is there a way to use the high quality DAC for the speaker by default?

There was a post where someone suggested using the AIMP player, I haven't been able to find it again (to give the proper credit), but it started because someone noticed how sound played different depending on what app played the sound or music.
It seems AIMP uses the Snapdragon 24-bit DSP (or DAC?) , which delivers a high quality output, I was actually surprised when I heard the difference.
My question is where or what could be changed so the default audio output uses the high quality DSP? So videos games and even ringtones and notifications (seriously it sounds much better) use it as well.
There is a great mod that activates the headspeaker when playing media, and even allows using both speakers with a stereo configuration, so perhaps using the DSP by default is also doable.
it was me who suggested the AIMP player in a previous post. i would however like to inform you that audio output using the OpenSL ES API instead of the default AudioTrack output will give you the raw audio of the DAC. Media Players which have this option will definitely sound much better. To my knowledge i have seen only VLC media player to support this feature (you have to change the output in setting unlike in AIMP). Custom sound mods are software level implementations which will just give you an amplified sound irrespective of quality. PowerAMP and MX has this option too but doesnt seem to work.
For better audio quality through speakers the default AudioTrack API works better.

Oh it was you, awesome recommendation indeed! Now normal audio output sounds muffled to me, the DAC audio quality is certainly much better.
Thank you, will look into it!

Sure man, ZUK has done something which modifies the audio quality before getting into our ears. I am sure its the audio driver. If someone can change that we should get a better audio quality.
Ummm I'm so unlucky, I've my JACK bricked :silly:. And I'm finding some way to route audio through USB using "USB-C to 3.5mm converter", same as Le2. I could not find a decent type-C headphone. I use Bluetooth reciever, and it's not even close to 3.5 mm jack. Any clue ? I'VE bought Poweramp, and it's useless now.
For those who use PowerAmp, update to latest build, i.e. 704 from official forum. Zuk Z2 does support HiRes Audio Output. Latest Play Store beta channel only have 703 build, which doesn't support HiRes Audio output in N.

When I enable hi-res output, it fails. I don't think it is working.

Latest version of MX Player (1.9.5 & 1.9.7) support change of audio output method. Although no big difference with movie files, maybe difference can be felt when listening to flac audio.

Maybe true, coz I found no difference even in movies with uncompressed 6 channel & 5.1 audio. But option exists, so we have hope for it to be working in future releases.
Update for Poweramp 704_universal - Doesn't work properly yet. No observable difference in quality even with flac. I've been using the 704 version for quite a while now, also on 3 different phones. None of the three have supported high res properly. On my OPX it usually caused the app to crash. Maybe with the long awaited update to v3 might make it work properly.

If, like me, your preferred player is Poweramp, you can make it sound like AIMP's OpenSL output. besides enabling OpenSL as output method, open this file /data/data/com.maxmpz.audioplayer/shared_prefs/com.maxmpz.audioplayer_preferences.xml, find the string osl_headset_float and set its value to true and save it.Then force close PowerAMP and open again, the audio quality will match that of AIMP. But anyways, if you are really a audiophile, using VLC (opensl output ofc) gives the best possible quality, just saying

I have the converter as well as ZUK Z2 (with my wife), I'll check if audio through USB-C works and if the hardware output works or not (provided my wife doesn't get cranky over my testing )

Recording audio noise canceling feature

Anyway to disable the noise canceling feature that google implemented for video audio recording?

A few days ago I saw a message (somewhere?) where the poster mentioned that the Open Camera app had an audio source option in the video recording settings that seemed to improve audio quality. You may possibly have to set the Camera2 API on in the settings as well (not sure of this) in order to see all the options. There is an "Unprocessed" option in the audio source options. I've not tested this myself but it sounds like it (no pun intended) has promise for audio in video recordings.
Thanks. Sounds alot cleaner. But audio seems to be more quiet.
