[Csnd] Csound for Android - get input from other apps

Hi all -
I'm hoping to make an Android app by modifying one of the CsoundForAndroid
examples.
I want the app to take audio from other apps (i.e. Spotify) as an audio
input stream it feeds to Csound. Ultimately I want the user to be able to
put effects on the music they're listening to.
I'm not sure how to set this up on the java side of things, but I did find
this class in the Android dev guide:
https://developer.android.com/reference/android/media/AudioPlaybackCaptureConfiguration
and I'm wondering if adding it to my CsoundObj (in Android Studio) could be
the key. Though I'm unsure how to implement this properly in java.
Thank you for your consideration!

Hello, I think the point of the example you found in Android Developer Guide is to capture audio inside the AudioRecord class. So, the way to get audio samples from the external application is likely to use the "read" method of AudioRecord. This will give you an array of float or double (audio samples), that can be used to fill the Csound input. I'm not sure how to do this with CsoundObj.java (if that is what you use). Johann

Hi Johann, Thanks for the info. I am indeed trying to do this with CsoundObj.java. It's already set up to feed audio to csound from the phone's mic, I'll see if I can alter that part of the code based on your suggestions. Though I am not super confident about doing this in Java, if and when I do get results I'll post them here.
