audio-checker 1.7 (Default branch)
02-02-2009
The aim of auch (audio-checker) is to visualize harmonics in musical recordings. Many tools show the spectrum, but this tool focuses on one or two specific octaves, with an indication of the tonica, sub-dominant(IV), and dominant(V). This way, notes, chords, and harmonics in a musical piece become clearer. It also supports other types of transformation (like wavelets, surface waves, strings, resampling, etc). Another feature is that this tool can compare incoming and outgoing audio to test external filters. License: GNU General Public License (GPL) Changes:|

AUDIOCFG(1) BSD General Commands Manual AUDIOCFG(1) NAME
audiocfg -- configure default audio device SYNOPSIS
audiocfg list audiocfg default index audiocfg test index DESCRIPTION
The audiocfg utility helps maintaining the audio and mixer device symlinks. Run with ``list'', it lists the available audio devices and shows the currently selected default audio device. Called with ``test'', it plays a tone of 2 seconds for each channel of the device with the index index. Called with ``default'', it sets the default audio device to the one with the index index. audiocfg needs access to /dev/drvctl and write access to /dev (when used with ``default'') to work. FILES
/dev/audio Symlink to default audio device. /dev/audio[0-9]* Available audio devices. /dev/audioctl Symlink to default audio control device. /dev/audioctl[0-9]* Available audio control devices. /dev/drvctl Used for finding the corresponding audio driver to an audio device. /dev/mixer Symlink to default mixer device. /dev/mixer[0-9]* Available mixer devices. /dev/sound Symlink to default audio device (for the difference to /dev/audio, see audio(4)). /dev/sound[0-9]* Available audio devices.
