Building a Custom Raspberry Pi DSP Platform – Interested to Hear What People Think
Hey everyone,
For the last few months I’ve been working on a project called “Alira Core”. It started as a personal DSP project but it’s slowly turning into something much bigger.
Unlike a lot of Pi DSP projects, this isn’t built around CamillaDSP or existing DSP software — I’m writing the DSP engine and control system myself.
Current features working so far:
- 8-channel routing
- 8-channel output matrix
- Parametric EQ on every channel
- High-pass and low-pass crossovers
- Delay per channel
- Polarity invert
- Mono summing
- Real-time web UI control
- Mobile/tablet control from any device on the network
- Low-latency audio pipeline
Currently working on:
- FIR filter support
- further optimisation
- UI improvements
- expanding the routing architecture
The hardware side at the moment is Raspberry Pi based, but the long-term goal is to build a flexible DSP platform that could be used for things like:
- active speakers
- DSP amplifiers
- home audio
- live sound
- studio monitoring
- custom installs
A lot of DSP platforms out there feel either very closed off, outdated, or limited in routing flexibility, so I wanted to build something that feels more modern and modular.
I’d be really interested to know:
- Is this something you’d actually use?
- What features would you expect from it?
- What would make you choose it over something like miniDSP?
