bb is an rc script for compiling and playing bytebeats on plan9: usage: bb [file1] [file2] Input is the body of a C function returning uchar. If no arguments are given, input is read from stdin; if one argument is given, input is read from file1; if two arguments are given, input from file1 and file2 are mixed in stereo. Playback is at 8kHz. DEL exits. eg: echo 'return ((t>>10)^(t>>10)-2)%11*t&64;' | bb
