audera is an open-source multi-room audio streaming system written in Python for DIY home audio enthusiasts.
The following section describes different options for deploying audera, either as a standalone streaming system or self-hosted with Home Assistant.
The audera server can be deployed on a Raspberry-pi, where the Raspberry-pi manages the audio input device, capturing and streaming all audio from the input device over the network. Any number of audera clients can connect securely to the audera server over TCP and can play audio through any speaker or output interface.
The following example is a simple Raspberry-pi only based implementation with auxiliary input / output(s) that supports active speakers,
+------------+ +------------+
| rp-i | | rp-i n |+ +---------+
| | | ||+ | n |+
| audera | TCP | audera ||| | active ||+
Streamer ----> AUX + {server} <------> {client} + AUX ---> speaker |||
| | | ||| | |||
| | | ||| | |||
+------------+ +------------+|| +---------+||
+-----------+| +---------+|
+-----------+ +---------+
The Raspberry-pi hardware can be improved by add-on DACs and amplifiers (like those available from Hifiberry), which can offer additional audio input / output interfaces and higher quality audio capture, streaming and playback.
The following example extends the simple Raspberry-pi implementation with Hifiberry DAC and amplifier add-on boards, which supports much higher fidelity passive speakers,
+-----------+
TV ----> OPTICAL + | +------------+ +------------+
| Hifiberry | | rp-i | | rp-i n |+ +-----------+ +---------+
| Digi+ I/O --> | | ||+ | n |+ | n |+
COAXIAL + | | audera | TCP | audera ||| | Hifiberry ||+ | passive ||+
+-----------+ | {server} <------> {client} ----> AMP2 ------> speaker |||
| | | ||| | ||| | |||
Streamer ----------------> AUX + | | ||| +-----------+|| | |||
+------------+ +------------+|| +-----------+| +---------+||
+-----------+| +-----------+ +---------+|
+-----------+ +---------+
The audera clients are natively discoverable by audio source devices that can be integrated directly into Home Assistant and managed by media players, like Music Assistant, which offers the ability to stream audio from local media files, streaming services, like Spotify, and online radio.
