Lossless uncompressed audio signal transmission over a local network (multicast) using open source and free software:
– end-device side: Jackd2 (or Pipewire), AES67 mai, Alsa-Webui, Jack-Webui, AaMoN Agent
– client side: AaMoN Manager

Latency depends on the hardware used (in general between 1 – 6 ms), in my case is built as follows: a control computer (standard PC with Windows 11), which controls and manages all other end-devices (Raspberry PI 3,4,5 and other arm computers or other standard PC with Linux OS). To achieve maximum transmission quality, the requirement is a Gbps local network (but working on Mbps too).

Of course, whole solution requires soundcards on all devices in network with the number of channels according to the user’s needs.

Software used:
Jack2 or Pipewire – main sound server on all devices
AES67 mai – designed to transmit multichannel audio over a local IP network (up to 8 channels) https://github.com/markmcconnell/mai
PTPdv2 – mandatory PTP master clock on dedicated machine (Rock-Pi in my case)
Alsa-WebUI – web interface for controlling soundcards https://github.com/JiriSko/amixer-webui
Jack Patchbay – web based graphical patchbay https://github.com/DatanoiseTV/jack-patchbay
AaMoN Manager – client/server setup utility to setup and control end-devices (network device)
AaMoN Agent – daemon running on Raspberri Pi soundcard for remote control

Requirements: Jack Audio Connection Kit (https://jackaudio.org/) and ASIO driver

Linux and MacOS versions will be avalaible soon (maybe 🙂 )

Latency depends on the hardware used and overall software settings (realtime kernel, jack, etc.) … in my tested rig with Tascam 16×08 soundcard is about 3ms on 8 channels (jack setup 48000/128 on both sides) works pretty fine.
Instructions, drawings, links and some videos coming soon …….
