DSP stands for Digital Signal Processor. The processor can be either a standalone signal processing device or signal processing integrated into other devices. A DSP is used to process or modify one or more signals. Since a DSP modifies the signal in the digital realm, analog signals must be converted to digital when entering the DSP and converted back to analog after processing, thus DSP devices that function with analog signals incorporate A/D and D/A conversion.
The processing or algorithms in a DSP often emulate analog devices such that a single DSP may replace what would have been a rack full of analog equipment.
Probably the most common use of the term "DSP" is to reference audio signal processing. An audio DSP can potentially provide a wide variety of signal processing via different algorithms available in the processor. An audio DSP could be a dedicated purpose, single channel processor, say just a delay output from one input, or it can be a multipurpose device with processing consisting equalizers, limiters, compressors, filters, routing, mixing, delay and so on for multiple inputs and outputs. An audio DSP may have a fixed configuration with pre-defined processing, a fixed internal configuration with user selectable processing or an open architecture where both the internal configuration and processing are user defined.
