NetBSD/src z13aLhp — sys/dev/audio audiobell.c audio.c
Improve audiobell (and interfaces with audio).
- Generate pseudo sine wave if possible. It may improve timbre.
If it cannot represent a sine wave, it falls back to a triangular
wave or a rectangular wave.
- Volume adjustment.
- Calculate playback frequency based on mixer frequency.
Now audiobellopen() initializes playback parameters other than
sample_rate, and new audiobellsetrate() sets sample_rate.
