# jack\_freewheel(1)

JACK toolkit client to control freewheeling mode

## NAME

jack\_freewheel - JACK toolkit client to control freewheeling mode

## SYNOPSIS

**jack\_freewheel \[y\|n\]**

## DESCRIPTION

**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.
