# jack\_meter(1)

Console based Digital Peak Meter for JACK

## NAME

jack\_meter - Console based Digital Peak Meter for JACK

## SYNOPSYS

**jack\_meter** \[ -f *freqency* \] \[ -r *ref-level* \] \[ -w *width* \] \[-n \] \[ *\<port\>*, ... \]\
 **jack\_meter** -h

## DESCRIPTION

**jack\_meter** is a basic console based DPM (Digital Peak Meter). I wrote it for quickly checking remote signal levels, without having to  run X11 to use a pretty graphical meter such as **meterbridge**.

The port parameter is optional - when missing then you have to connect  up the meter to an input port manually.  If more than one port is specified then the inputs are mixed.

## OPTIONS

- **-f** *freqency*

  How many times per second to refresh the meter. Default is **8**.

- **-r** *ref-level*

  The reference signal level for 0dB on the meter.

- **-w** *width*

  The width of the meter (number of characters). The default is **79**, one less than the typical terminal width. **-n**\
   **Outputs meter level as a number in decibels instead of a bar graph display.**
