Stream notes

A quiet pad for scraps about packet timing and audio that refuses to stay in lockstep. Nothing ships from here.

  1. Bufferbloat is not “the wifi”

    If the capture shows a sawtooth of delay with a full send queue, look at the bottleneck’s standing queue before you blame the radio. A 50 ms target and a too-large burst size will invent jitter that the encoder then tries to outrun.

  2. NTP vs the sound card

    Wall clocks can be stepped; sample clocks only slew. Mixing the two in one session log makes a clean 1 kHz tone look drunk. Stamp with the device clock, convert later, and write down which converter you used.

  3. Why this hostname

    The label is a nonce so old bookmarks do not collide with a real project. If you arrived from a search index, there is no product behind the DNS name.
