I usually use the Compressed saving option; unfortunately, I just noticed that all my divisions within tracks disappear!!! They are very important for my music, and I guess they use very low memory to be stored: is it possible to preserve them, in the future version of the wonderful Audacity?
The way that “Save a compressed copy” works, is that each track is rendered (effectively the same as exporting) as OGG files, and these OGG files then replace the normal audio data. As when exporting a track, the track data forms a single audio file.
Nothing is impossible, but it would require a substantial change to how compressed saving works. Rendering tracks is currently an all or nothing affair for tracks - either mix and render the entire track, or nothing - Audacity can’t render just part of a track, so that facility would need to be written before work could begin on rendering single clips when saving.
In my opinion, it would be ‘possible’, but would need to be part of a bigger reworking of how we save projects (a lossless compressed copy of the project might be another nice feature).
Give the possibility to save the divisions present inside each track (instead of merging them all during the compression process): indeed, track divisions are essential -e.g. for music composing- and -especially if you have many- labeling them all and restoring them later would be very time consuming!
If there is a command line encoder available for OptimFrog, then it should be possible to export as OFR using Audacity’s “external program” export option:
“File menu > Save Other > Export Audio”, then select “(external program)” from the Save as type dropdown menu.
