In commercial AV, a digital signal processor (DSP) is a device or software engine that processes audio — mixing, equalization, gain control, noise reduction, routing and acoustic echo cancellation — between a room's microphones, loudspeakers and conferencing system.
A DSP is what makes a room sound consistent: it balances microphones automatically, prevents feedback, and removes echo for remote participants. Medium and large conference rooms, boardrooms and training rooms typically use a dedicated DSP tuned during commissioning.
Where this matters: Commercial audio systems — see how AV Company New York applies this in real New York projects.
