Notes

  • Sebastian is looking into pitch-preserving audio stretching
    • Richard started a while ago, has a python prototype, which needs to be ported to C++/Audaspace. Sebastian picked this task.
    • Did not research: there are different algorithms speech vs music correction. For now we follow the initial algorithm and implement what is considered a speech correction.
    • There are some unknowns how exactly it fits into Audapsace, hopefully Joerg could help with some knowledge. Sebastian will talk to him.
  • Sebastian has an approved patch for scrollable area: make it so collapsed redo panel does not occlude actual sequencer content
  • Sebastian looked into pulseaudio backend for Audaspace issues:
    • AV sync playback where scene frame would not advance the scene frame
    • Not easily reproducable, complicates troubleshooting
    • Maybe explore Pipewire as an alternative
      • Seems what other audio software is switching to, and is also what Linux distros are switching to as well.
  • Aras did a lot of bug fixes. Some of them are already ported to be in 4.2.1, others need to be ported still.
  • Aras looked into VSE thumbnail code, mainly for performance reasons
    • Need to avoid creation of GPU texture for every thumbnail on every redraw
    • And try to solve flickering
