Checklist

• I made sure that there are no existing issues - open or closed - to which I could contribute my information.
• I have read the FAQ and my problem isn't listed.
• I have taken the time to fill in all the required details. I understand that the feature request will be dismissed otherwise.
• This issue contains only one feature request.
• I have read and understood the contribution guidelines.

Is your feature request related to a problem? Please describe.
I'm also quite confused by the options for "Audio source" in the app settings.
For example, what does "Android default" mean, and why isn't it the default option?

Could this setting be made clearer or add information about what each option means and how one would choose an audio source?

In Readme nearly nobody will find it. I think the best would be a short description under each radio button. Alternatively, a new entry in FAQ (in the app).

I think the audio sources in the app correspond to some of the MediaRecorder.AudioSource options from Android.

Voice-Recorder/app/src/main/kotlin/org/fossify/voicerecorder/helpers/Config.kt

Lines 30 to 38 in dcdce9a

	fun getAudioSourceText(audio_source: Int) = context.getString(
	when (audio_source) {
	MediaRecorder.AudioSource.DEFAULT -> R.string.audio_source_default
	MediaRecorder.AudioSource.MIC -> R.string.audio_source_microphone
	MediaRecorder.AudioSource.VOICE_RECOGNITION -> R.string.audio_source_voice_recognition
	MediaRecorder.AudioSource.VOICE_COMMUNICATION -> R.string.audio_source_voice_communication
	MediaRecorder.AudioSource.UNPROCESSED -> R.string.audio_source_unprocessed
	MediaRecorder.AudioSource.VOICE_PERFORMANCE -> R.string.audio_source_voice_performance
	else -> R.string.audio_source_camcorder

Hi there. Would choosing any of the aforementioned audio sources allow recording of two-way voice or Voip communication? Like "call recorder". Thanks.

I don't think you will be able to record calls because VOICE_CALL is an audio source option, but there are some options from the Android API documentation:

• VOICE_COMMUNICATION Microphone audio source tuned for voice communications such as VoIP. It will for instance take advantage of echo cancellation or automatic gain control if available.

• VOICE_CALL Voice call uplink + downlink audio source
  Capturing from VOICE_CALL source requires the Manifest.permission.CAPTURE_AUDIO_OUTPUT permission. This permission is reserved for use by system components and is not available to third-party applications.

Thanks for clarifying. I don't suppose you know, or if it's at all relevant. What Android API feature music recognition applications such as Shazam take advantage of, as they allow recognition of sound(music) internally , from another application, hence my assumption that they can capture audio output? Sorry if above is confusing.

I don't know anything about the internals of Shazam, but I'd guess that Capture audio playback is probably similar.
