    immer man nicht einfach Pulse nutzt. #pulseaudio kann zwar auch nativ Netzwerk, ist aber eher nervig in der Bedienung und unzuverlässig. Über nc hats durch Buffer unschön viel Delay. Hab nun #ROCToolkit roc-streaming.org/ gefunden. Kann sich das Audio von Pulse(monitor) greifen und per RTP mit wenig Latenz auf andere Geräte rausjagen. Leider fehlt in der Doku etwas Quickstart, aber überschaubar komplex und bisher keine Probleme mit gehabt.

    I'm happy to announce the first version of Roc VAD, a virtual audio device for macOS that can stream to/from #PulseAudio, #PipeWire, Android, and others.

    Link:
    github.com/roc-streaming/roc-v

    It also provides a gRPC interface with full control of the driver, which allows reusing driver in other projects.

    got support for new "speexdec" resampler, that combines speex for fixed rate convertion and decimation/expansion for dynamic part needed to compensate clock drift.

    github.com/roc-streaming/roc-t

    It works surprisingly fine. The decimation affects only 5-20 samples/second. When base rates are equal, it's VERY cheap. And it follows scaling factor with better precision than speex.

    This resampler can be used as a fallback for CPU-constrained environments.

    Two C API improvements recently landed develop branch of

    🔹 Removing slots on the fly.

    "Slots" represent connected peers, so this is useful when peers enter and leave session dynamically.

    🔹 New packet encoder/decoder API, similar to sender/receiver, but networkless.

    You push raw frames and get encoded packets, or vice versa, and you deliver packets by yourself. This allows using roc with third-party transports like libjuice and libdatachannel.

    Recently spent some time optimizing latency over Ethernet.

    So far, achieved 7ms for transport + 12ms for two USB sound cards.

    This is the photo of my test bench for measurements.

    Legend: R1, R2 - ; S0, S1, S2 - sound cards; L1, L3 - jack cables; L2 - ethernet cable.

    Roc runs on R1 and R2 and streams sound from S1 to S2.

    On PC, I run that writes sound to S0 output, reads it back from S0 input, and measures latency.

    [1/3]

    I had a lot of fun last weekend, adding surround sound support to , with conversion between surround layouts (downmixing and upmixing).

    (E.g. if network layout is surround 7.1, but sound card is 5.1, it's automatically downmixed)

    Learned lots of new! I first discovered remixing algorithm from [1], but ended up using downmixing tables from dolby [2][3].

    Also added support for large multitrack channel sets up to 1024 channels.
