All CSDs play at 48000 Hz with the selected ksmps (default 64). Stop playback to change it. Overrides apply in memory; source files stay unchanged.

50 ms keeps the original ~43 ms audio queue. Larger buffers prefill more audio and add latency. Stop playback to change the buffer.

No sound on iPhone? Open in Safari, raise media volume, check the speaker/AirPods route and tap Resume audio if shown. On older iOS, turn Silent Mode off. A changing digital output level confirms Csound output, not audible sound.
