Description
sokol
is a thin wrapper around sokol,
which in turn is a library of "Simple STB-style cross-platform libraries
for C and C++, written in C.", that provide access to graphics/audio/input
processing.
Each .h
file in the sokol source code is well-documented as can be seen here:
Example from @VROOTDIR/examples/sokol/sounds/simple_sin_tones.v
import timeimport mathimport sokol.audio
const sw = time.new_stopwatch()const sw_start_ms = sw.elapsed().milliseconds()
@[inline]fn sintone(periods int, frame int, num_frames int) f32 { return math.sinf(f32(periods) * (2 * math.pi) * f32(frame) / f32(num_frames))}
fn my_audio_stream_callback(buffer &f32, num_frames int, num_channels int) { ms := sw.elapsed().milliseconds() - sw_start_ms unsafe { mut soundbuffer := buffer for frame := 0; frame < num_frames; frame++ { for ch := 0; ch < num_channels; ch++ { idx := frame * num_channels + ch if ms < 250 { soundbuffer[idx] = 0.5 * sintone(20, frame, num_frames) } else if ms < 300 { soundbuffer[idx] = 0.5 * sintone(25, frame, num_frames) } else if ms < 1500 { soundbuffer[idx] *= sintone(22, frame, num_frames) } else { soundbuffer[idx] = 0.5 * sintone(25, frame, num_frames) } } } }}
fn main() { audio.setup( stream_cb: my_audio_stream_callback ) time.sleep(2000 * time.millisecond) audio.shutdown()}
