Can i use your library as a wrapper for jack2 to get the ability to work with external usb audio interfaces?

Kind regards

Hi,

I am looking to build Karaoke App for Android but existing sound API is lacking.

Requirement:

1. Play an audio file in the background(music) and record user voice thru Microphone
2. Save record of the Audio background mixed with the microphone as MP3 format

Is this project helpful for this?

Regards;

The wiki page could be edited by anyone.Please fix it

Hi Peter,

first of all thank you for this amazing project.

I've been working with Patchfield for a while, and I'm facing some issues when using the samples (the Patchfield controller with lowpass module) in Nexus 5 (Android L).
After playing for a few minutes, the audio quality begins to deteriorate (sometimes it stucks in a loop, playing the same half second or so for a few seconds), and after a while backs to normal.

This behaviour seems to only happen with Patchfield based applications. I've tested the opensl_stream sample for relatively long periods of time (~45 minutes) without issues.
The only scenario, using pathcfield, in which this issue does not seems to happen, is when an audio file is used as source instead of device microphones (through PcmSample).

I've been searching in systrace files for some clue that could indicate the cause of this issue, but can't find any. FastMixer is called regularly (every ~5ms, as expected) and there are no gaps in frames ready counters.

Best regards,
Bruno

Add possibility to select audio data source from external audio card

I have external audio card, Nexus 7 can work with external audio card, but in SDK I have no see any for this.

mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);

but need something like this:
mRecorder.setAudioSource(MediaRecorder.AudioSource.EXTERNAL_CARD_MIC);

http://www.jakartanotebook.com/images/products/38/18/2387/1/vztec-usb-7.1-channel-sound-card-adapter-vz-ua3915-3.jpg

also need advanced audio API for using - Line IN from external audio card.

I wanted to create open source universal oscilloscope(with input data source plugins system) for android (also with a possibility to get data from 1.5 USD USB audio card), but I can't to do this easy.

this app can work with external audio card https://play.google.com/store/apps/details?id=de.sobe.usbaudio

but I think need SDK support.

There is a dead link under the Project layout section of README.md file:
