Digital Signal Processing (DSP) is a method of manipulating and processing audio signals using digital computers or specialized digital signal processors. DSP can be used in a synthesizer to produce a large variety of sounds and effects, including filtering, modulation, and distortion. Digital versions of classic analog effects like reverb and delay can be produced using DSP algorithms, as can new and distinctive sounds that are impossible with analog synthesis.
For instance, DSP can also be used to design intricate modulation routings and sophisticated envelopes in a synthesizer’s control section. DSP can be used to produce expressive and responsive sound synthesis when combined with MIDI data. Large memory capacities are another feature of DSP-based synthesizers that enable the creation of more intricate and detailed sound programs and the simple storage, recall, and editing of sound parameters.
