Description Dean Jackson 2023-04-19 14:27:41 PDT

From our audio team:

Safari is currently using the following AudioSession `category` / `mode` combo: `.playback` / `.default`. The signal processing done by `.default` mode is not appropriate for video playback in general. It’s appropriate for music playback. Ideally Safari would use `.default` mode for playback of music, and `.moviePlayback` mode for playback of videos. The difference in “signal processing” between `.moviePlayback` and `.default` is the reverb preset that gets used when spatial audio is on.
