soundeditor - digital audio recorder/editor
soundeditor [ -display displayname ] [ filename ]
soundeditor provides a graphical interface for recording, playing and
editing AIFF format soundfiles. Features include:
- Realtime audio recording and playing
- Tape recorder-style transport controls
- Graphical audio waveform display
- Cut & paste editing of audio data
- Fade-in and out, level, echo, pitch and reverse effects
- Undo/redo for editing operations
For more detailed instructions on using soundeditor, access the on-line
help facility via the "Help" menu item on the right side of the main
Specifies the X display to use. If none is set, uses the value of
$DISPLAY. If $DISPLAY isn't set, uses ":0". Note that sound will
be played on the host running soundeditor, not the redirected X
Specifies an AIFF or AIFF-C soundfile to load on start-up. (All
files are saved in uncompressed AIFF format, however.)
Specifies that the program should run in the foreground rather than
forking and running in the background (normal operation).
soundeditor requires an SGI system with an Iris Audio Processor in order
to audition sounds. The program will run on systems with no audio
hardware, but the record and play functions will be disabled.
Soundfiles in formats other than AIFF or AIFF-C must be converted before
they may be used within the current version of soundeditor. Use sfconvert
or soundfiler to accomplish the conversion.
soundeditor saves all files in uncompressed AIFF format. Mono, stereo or
4-channel files are currently supported. Sample bit widths may be 8, 16
or 24 bits.
soundeditor creates temporary files during editing in a directory
specified by the environment variable TMPDIR. Soundfiles can become
quite large and it may be necessary to set TMPDIR to a directory on a
disk drive with enough free space. For example, a stereo soundfile
recorded at 44.1kHz will require approximately 10 megabytes of disk space
per minute of recording.
soundeditor works in conjunction with apanel, the Audio Control Panel,
where input source and levels may be set.
