Audio sometimes cuts out on high CPU usage #50

Closed hinto-janai closed 1 year ago

hinto-janai commented 1 year ago

OS & Version

Festival v1.1.0

Bug

When running other CPU intensive tasks, Festival's audio sometimes briefly cuts out.

Maybe this is acceptable if the CPU really was at 100%, but it happens even when not fully utilized.

Steps

  1. Play audio
  2. Run other CPU intensive task
  3. Experience audio cut out

Fix

Increase in-memory audio buffer, decrease message leeway for Audio, make decode loop more efficient.

As an optional thing, the audio thread could potentially be made realtime if rtkit is available?

Right, thanks for the reminder. It was previously on a high-priority thread, but after switching to manually decoding/demuxing, I forgot to re-add it. Realtime would be nice but I'm not sure if there's good cross-platform APIs for it.
