Snd

Written and developed at CCRMA by Bill Shottstaedt, SND is a sound editor modeled loosely after Emacs, an old, sorely-missed PDP-10 sound editor named Dpysnd. It can accommodate any number of sounds each with any number of channels, and can be customized and extended using guile and Ruby. It can be customized and extended using either s7 (included in the Snd sources), Ruby, or Forth. Snd can be started on any PlanetCCRMA Linux workstation by selecting the application on the PlanetCCRMA menu and the editors tab. Otherwise SND is started by typing the 'snd' command on a terminal window or shell.

To get started, go to the file menu, and open a sound file. To hear the sound, click the 'play' button. To see an fft, click the 'f' button on the left. The left mouse button is used for most pointing operations; the middle button pastes in the current selection; the right button brings up the SND pop up menu. Make sure you go through the help pull down menu to find more about all the features SND. In addition to this there is an enormous amount of information in the SND manual or search its documentation on its index

Editing soundfiles with SND

To edit soundfiles using SND, good advice is to use 'emacs-like' keyboard combinations (see below), and then try them on a SND listener window. To make things easier start with a short (3 secs) mono (one-channel) soundfile.


c-x means control-x or the keyboard combination <ctrl>-<x>
M-x means meta-x and at CCRMA is the keyboard combination <esc>-<x>


If you have a soundfile in the active window try the following combinations and watch the cursor in the displayed soundfile active window. If you don't have a soundfile you can use the open command in the file pull-down menu of SND.

c-a: move cursor to window start
c-e: move cursor to window end
c-v: move cursor to mid-window
c-l: position window so cursor is in the middle
c-f: move cursor ahead one sample
c-b: move cursor back one sample
c-q: play current channel starting at cursor
c-t: stop playing
c-[Space]: start selection definition
c-m: place (or remove) mark at cursor location
c-j: goto mark
c-w: delete (cut) current region
M-w: (copy) current region
c-y: paste in last deleted region
c-_: undo
c-x c-s: save your current edition.
