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 

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.

least it doesn't block Max.

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.

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
