DSP
Audio processing chip
DSP stands for digital signal processing, a field involving the manipulation of signals—typically audio, video, or sensor data—using mathematical algorithms implemented in software or specialized hardware.
In audio contexts, DSP handles effects like reverb, compression, and equalization: The mixer has built-in DSP for vocal processing.
A DSP can also refer to a digital signal processor, a specialized microchip designed for these calculations.
In advertising technology, DSP means demand-side platform, software that lets advertisers buy digital ad space programmatically. (Lowercase dsp is informal.)
