Proposed Feature

Real Time Adjustment means that when adjusting the parameters of an effect, you can do so AS you are listening - imagine playing with a graphic equalizer as you are listening to a sound - today you have to make a change, preview it, and then make another change.


Developer Backing

  • Many. Ask on audacity-devel.


Use Cases

  • Nearly all users of Audacity for Audio.

Equalization in particular would benefit enormously from real time processing.

Such a feature would allow you to define the length of the loop (default all of the selected part of the track). In general one would want both slider and textual data entry - the former is easier to 'play with' the latter is sometimes more conveniant when you KNOW what number you want. Of course the two would be synchronised.....

Another example as to why RealTimeAdjustment would be so useful is the following: Imagine you have a voice recording that you want to alter the eq of. At the moment, the preview function will only playback a small portion of the total recording (and as it's a vocal, there's a good chance some of it will be silent). Thus it's a bit hit-and-miss. With RTA, you can fiddle as you go, giving you a significantly improved workflow!

Use of MIDI controllers for real time adjustment would be cool, too.

6/9/05 Extension: effects should be stackable, and non-obtrusive to the original audio. This would increase effect flexibility tremendously, by allowing for different effect orders, and eliminiating the need for many backup copies of original and intermediate/trial audio files

There is a definition LADSPA_IS_REALTIME in LADSPA_Properties structure. If a plug-in has it, then it can be treated as real-time ready plug-in automatically--Prokoudine 00:06, 10 February 2006 (PST)
