my goal is to loop a piece of audio in a short as possible length of time (or to loop it as fast as possible)
No it is not
I
Why are you trying to loop it
MG
cus i am making an audio app which allows users to define custom looping points for a playing audio track, and freely switch between those points
I
You are seem to be trying to get to it breaking through a wall with your forehead
I
You can always detect that you are falling below the audio buffer and duplicate your samples to cover it
I
Are you using any sort of player or are you writing the samples manually?
MG
Are you using any sort of player or are you writing the samples manually?
what do you mean
I
I mean that you could go for saving the audio in a file and pointing a MediaPlayer instance to it or writing all the samples directly to an audio output via AudioTrack API f.e.
MG
ok, which would be faster?
I
The second one of course
MG
ok
I
Though there is a certain amount of work you have to do in order to achieve something. E.g. you must keep an eye on your samples, buffers, and deliver them at a certain speed
MG
so more room for errors?
I
Generally speaking, yes
MG
ok
I
But also way more flexibility without the need of writing anything to files
MG
would Obie/AAudio/OpenSL ES be faster than AudioTrack?
MG
or would those not be targeted for performance
