            bufsize += len - freebuf;
            unsigned char *tmpbuf = new unsigned char[bufsize];
            memcpy(tmpbuf, audiobuffer, audiobuffer_len);
            delete [] audiobuffer;
            audiobuffer = tmpbuf;

May be worth tracing bufsize vs audiobuffer_len (though by the look of
things it should always be greater)
