Loop between end and start (when playing in Audacity)

I’m trying to get a good loop between the start and end of the track, however when I hold shift and click the play button it either plays the whole track or just the bit between the brackets. Instead I want it to just loop close the end and close to the start so that I can hear whether I have a good good loop cut. How I make it so rather than Audacity play through the whole song, it just plays the end and start? I tried using the brackets but they don’t seem to wrap around like this.

Audacity does not yet have quite what you want, though I would be happy to support a feature request for this.
Please feel free to propose what this feature is, and how it would work, in the “Adding Features” part of the forum: http://forum.audacityteam.org/viewforum.php?f=20
It can then be discussed by other interested parties, and hopefully appear as a new feature in a future version of Audacity.

Creating long loops in Audacity is a bit tricky and not very user friendly, but there are a few techniques that can help:

The current version of Audacity now has shortcuts to jump to the selection start Ctrl+[ or jump to the selection end Ctrl+] http://manual.audacityteam.org/o/man/view_menu.html#start
These shortcuts can also be customised if required: http://manual.audacityteam.org/o/man/keyboard_preferences.html (though I find the default shortcuts work well and are easy to remember).

We can take advantage of the fact that, when the loop points are correct, the section before the loop point should match exactly with the section after the loop point. This is something that we can easily test with Audacity using the “Cut Preview” feature (shortcut key: C)
The amount of audio played before / after the cut positions can be configured in Preferences: http://manual.audacityteam.org/o/man/playback_preferences.html

A quick and easy way to test a loop point:

  1. Effect menu > Repeat. Set the number of repeats to 1.
  2. Play across the middle of the highlighted section
  3. Ctrl+Z to undo and return to the selection in step 1.
    Note that “Repeat once” is now available by pressing Ctrl+R (repeat last effect), and will remain available until you apply some other effect.


    The following code can be run in the Nyquist Prompt effect. I think that it should work OK on Windows. How well this works will depend on the computer, sound card and sound system configuration. Nyquist is not able to do anything about that so it will either work for you vor it won’t.
    What it does is to play the last 1 second of the selection followed by the first 1 second of the selection.
(setq dur (get-duration 1))
(setf s
  (extract-abs 0 2
    (sim
      (extract-abs (1- dur) dur s)
      (at-abs 1 (cue (extract-abs 0 1 s))))))

(s-save s (truncate (* dur *sound-srate*)) "" :play t)
"Done"

If you want it to play several times, you can just repeat the “s-save” line like this:

(setq dur (get-duration 1))
(setf s
  (extract-abs 0 2
    (sim
      (extract-abs (1- dur) dur s)
      (at-abs 1 (cue (extract-abs 0 1 s))))))

(s-save s (truncate (* dur *sound-srate*)) "" :play t)
(s-save s (truncate (* dur *sound-srate*)) "" :play t)
(s-save s (truncate (* dur *sound-srate*)) "" :play t)
"Done"

I deleted you “hello” post in this topic. Such posts do not help in achieving a quicker response - they just waste time for the forum moderators.

I cannot believe it doesn’t have such basic functionality. Astonishing. And tell whoever designs the UI to learn the concept of “intuitive”.

You are welcome to submit a patch that adds this functionality for consideration by the development team.
See here for more information about developing Audacity: http://wiki.audacityteam.org/wiki/Developer_Guide

If you have any specific suggestions that you think will help to make Audacity more intuitive, please post suggestions on this forum board: http://forum.audacityteam.org/viewforum.php?f=20
Just criticising and moaning does not help anyone. Audacity will only improve as a result of people taking the time and trouble to make it better. There’s a hint in there for you to contemplate.
