jack_freewheel - JACK toolkit client to control freewheeling mode
jack_freewheel Turns freewheeling mode on (y) or off (n). While in
freewheeling mode, the JACK server does not wait in between process() calls,
and does not read or write data from/to any audio interface. That results in
the JACK graph processing data as fast as possible. Freewheeling makes fast
exports to files possible.
There is no useful reason to use this tool other than testing.
JACK clients that use freewheeling will turn it on and off themselves.
