The digital audio signal, fromwhose theorigin inputmay isbe transformedanalog (by conversion to thedigital) or be in an already digital source (asuch streamas ofan numbers)audio infile, audioor hardwarea and[[software passedsynthesizer]]), tois astored in temporary pieceallotments of computer memory, called [[Data buffer|buffers]]. ThenOnce itthere, isthe modifiedsoftware effect processor modifies the signal according to a specific algorithm, which creates the desired effect. After this operation, the signal ismay be transformed from digital to analog and sent to thean audible output, stored in digital form for later reproduction or editing, or sent to other software effect processors for additional processing.
