Dedicated hardware that processes audio signals in real-time — the brain of any commercial audio system.
Common DSP manufacturers in AV:
- QSC (Q-SYS Core series)
- Biamp (TesiraFORTÉ, Server series)
- Crestron (DM-NVX-DSP)
- Shure (IntelliMix)
- Bose (ControlSpace)
Typical processing:
- AEC (echo cancellation)
- Noise reduction / gate
- EQ (equalization)
- Compression / limiting
- Routing and mixing
- Feedback suppression
- Delay alignment
Key points:
- Every conferencing room needs a DSP (even if built into a sound bar)
- Choose based on I/O count, Dante/AES67 support, and control integration
- USB audio output from DSP to PC is the cleanest way to connect to Teams/Zoom
