# jack\_bufsize(1)

JACK toolkit client to change the JACK buffer size

## NAME

jack\_bufsize - JACK toolkit client to change the JACK buffer size

## SYNOPSIS

**jack\_bufsize bufsize**

## DESCRIPTION

**jack\_bufsize** jack\_bufsize sets the size of the buffer (frames per period) used in JACK.  This change happens on-line (the JACK server and its clients do not need to be  restarted).\
 When invoked without arguments, it prints the current bufsize, and exits.
