  • Upload soundfile more than 20 mb size to buffer?

There should be no inherent file size limit. Are you sure that the file got successfully stored? This seems like a corrupted file error. Can you send your Sc code?

Hi Giuliomoro, I'm getting back to the topic "how to play bigger sound files". For example, I can't play longer .wav file that is longer than 15 minutes. It works when I play the same file with a shorter length (i.e. 48000*600 samples). It seems there is some buffer or capacity limitation on Bela. Do you know what could be the issue?
Thanks"

it shows me there is no buffer data. But it works when I reduced the length of the same sample...

ok, so this seems to be working! In SuperCollider, it is possible to stream audio from a file and to avoid loading a bigger sound file to a buffer which causes troubles with the limited RAM (512) of Bela.
So here is the possible solution in SC code:

(
SynthDef(\help_Buffer_cue,{ arg out=0,bufnum;
    Out.ar(out,
        DiskIn.ar( 1, bufnum )
    )
}).add;
)

(
s.makeBundle(nil, {
    b = Buffer.cueSoundFile(s, Platform.resourceDir +/+ "sounds/a11wlk01.wav", 0, 1);
    y = Synth(\help_Buffer_cue, [\bufnum, b], s);
});
)
