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.

Keybindings

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.

Playing a Soundfile

To play a sound file from a place other than the beginning:
- Activate sync or sync/unite modes in the lower right check-boxes
- Create a synchronize marker by:

 '''c-s-M''' (control-shift capital M)

You should you get markers for all the channels.

- To play from that location just click on the triangle in any of the markers.
- Playback should start.
- You can also move this markers and even 'rock the reels' by dragging the mouse.

More complex operations:

- Move forward or backward in the soundfile using the following combinations:

      c-a            ;;; move cursosr to the beginning
      c-u 0.4 c-f    ;;; move cursor forward 0.4 seconds
      c-e            ;;; move cursor to the end
      c-u 1.12 c-b   ;;; nove cursor backwards 1.12 seconds
      c-[Space]      ;;; start selection definition
      c-e            ;;; a selection of 1.12 seconds

Note: These combinations and more can be viewed on the online Help menu at the overview command at the right side of the SND active window.
