Saving waveforms

Unread postby floyd6 » Tue Mar 07, 2017 10:45 am

Is it possible to somehow save the waveform so I don't have to wait for it to regenerate next time I launch the program?

Disk cache

Unread postby floyd6 » Tue Mar 07, 2017 6:25 pm

How to stop the program from creating a new cache file for the same audio every time I open it? Why won't it use the old one or at least delete it on exit?

I honestly can't remember the reason we never implemented reuse of audio cache files. Probably something related to cache management and preventing misassociating cache files with source files. (E.g. you load audio from file A, which then gets cached with key X, then later you load audio from file B, but somehow B receives key X too and you then get audio from A instead of the intended B.)

What Aegisub does support is direct reading from uncompressed (PCM) WAV files. If you decode the audio track you need to PCM WAV and load that into Aegisub, it will open instantly without any caching. The decoding could also be semi-automated with a batch file or similar.

If you see audio cache files hanging around after closing the audio, that's a bug. I haven't heard about that before.
Do not PM me asking for help with Aegisub, Automation, karaoke or anything like that, I won't reply.
