Hi list,

right now I'm trying to use Csound on android to play audiofiles. Usually, I would do something like this:

instr 1 
	asig diskin2 p4, 1, 0, 1
	outs asig, asig
endin

and use the score event

i 1 0 10 "inputfile.aiff"

to play the file. Now I read a little on the structure of the apk's and I wonder how to achieve the same functionality, since there are no absolute paths in the apk. First I tried to put "inputsound.aiff" into res/raw/ but this would not work. I found out, that assets/ might be the better position, but then I don't know how to provide the file to Csound. The access to assets works via the AssetManager which allows to get filestreams from the packed archive. Does Csound understand these Streams? I suppose not. So then how do I get the file from assets into diskin2?

Best,
Martin

Hello Martin,

You need to write your own method to extract the file. For example: you have 
a file as a resource in your apk (kept in the res/raw folder of your 
project) whose id is R.raw.something:

- InputStream stream = getResources().openRawResource(R.raw.something)
- Create a file output stream of your choosing, so you say what file name 
and folder to use (maybe BufferedOutputStream to be efficient?)
- Use a byte[] buffer to read the bytes efficiently
- while ((bytesRead = bin.read(buffer)) > 0) bout.write(buffer, 0, 
bytesRead);

And there you have a new file, you know its name and location.

All the best,

Jacques

Hi Jacques,

hmm, I almost thought in this direction, but I'm very new to android to find all the classes. Thank you for your tip, this will make it a lot more easy to get it done.

Best,
Martin
