Making use of audio file metadata #122

Open yaxu opened 5 years ago

yaxu commented 5 years ago

It could be nice to be able to make use of audio file metadata such as cue points.

These can be embedded in wav files.. It seems this isn't generally accessible to SC but might be on the way: https://scsynth.org/t/reading-file-markers/241/6

We have talked about making use of off-line analysis, such as onset detection to index inside audio files, in the past.

If you export markers from audacity, you could already use those. It is just a little unclear how the parameters would look like.

Replay Gain would also be interesting to have. One could use it to predefine amp settings for a loudness balanced sample set.

In the case of audacity regions, I suppose it would really be tidal rather than supercollider that needs this info, as the main event scheduler is there.. As you might want to set a sound in time relative to its middle or end

Yes! I always missed this feature with samplers, for example to align a cymbal swell crescendo to a beat.

Here in section 3 Bel refers to points (rather than regions) in a sound object as pivots, after Duthen and Stroppa, https://hal.archives-ouvertes.fr/hal-00134179/document
