GNoise - A wave sound file editor

gnoise [ file ]

gnoise is a GTK+ based wave file editor. It uses a display cache and a double-buffered display for maximum speed with large files. It supports common editing functions such as cut, copy, paste, fade in/out, reverse, interpolate, normalize and more with unlimited undo. The primary design objectives are stability, speed and the ability to handle big files (i.e. 70MB ripped CD tracks) easily. In fact gnoise has been reported to work with >500MB files although the author doesn't happen to have any wave files that size laying about :)

Note that gnoise is a destructive editor: all editing operates directly on the soundfile, work on a copy of something you really don't want to lose. Note also that you should not mix the use of the disable undo option on different edits within an editing session (ie. if you start editing a file with undo disabled then leave undo's disabled until you close the file, at which point you can turn undo on and re-open the file if you wish to edit with undo capability).

Left click unselects any selections

A right click sets the playline.

A left drag will create a new selection unless you start it on the end of a pre-existing selection (the mouse cursor will turn into a double headed arrow) in which case it extends the selection.

Clicking play begins playback. If there is a disjoint selection (the starting and ending of the selections for all channels don't match) or no selection, playback will commence at the the playline and play to the end of the file. If the selection begin and end is the same for all channels (non-disjoint) then just the selection will be played.

The + zooms in, - zooms out, and Selection zooms to, uh, the selection. Yes, you can zoom in to single sample resolution.

Clicking stop does what you think as well.

Recording: Set the parameters in the dialog, give a filename and hit record. Adjust levels and input device using gmix or your favorite mixer program. For best results, make sure none of the source material clips (the buttons above the levels). If you don't like the take, just hit stop, then hit record again and it will record over (not append to!) the previous take.

Edits modify the current selection.

When you first open a file GNoise will (optionally) create a display cache file so it can draw it very quickly (also know as a 'peaks' file in Sound Forge terminology). This cache file is stored in the same directory as the wave file itself and is given the name '.<orignal file name>.dcache'. By default, all zoom levels below 1:512 will not be cached, but generated on the fly.

file

Specifies a file that will be opened at startup.

~/.gnoise/opendir Directory where gnoise openend the last file. ~/.gnoise/gnoiserc In this file the user preferences are stored. ~/.gnoise/gtkrc The custom gtk widgets within gnoise support setting colors through the normal gtkrc mechanisms.
