This one might help:

To have it resize the buffer use the ‘replace’ method for importing the
mp3. I don’t have any comparisons regarding decompression speed, but at
least it doesn’t block Max.
A ususal this is beta and might crash (especially the possible arguments
are untested). The error mesages you will get are normal and due to the
fact that the decoder tries to decode ID3 tags and whatever non-mp3 data
there is in your file. Usually this won’t hurt.
In addition decoding mp3 might be illegal where you are (at least
without paying a license fee)… so be warned.

If you set the buffer size to zero first, it will automatically resize on import. I had to use import, because i wanted the audio stream of a movie.

#P window linecount 1;

Have another look at help file of buffer~. You can append arguments to the import message to avoid setting the bufffer size to 0 first. I use

import 0 -1 2
