How to Create Delay-based Audio Effects on the TMS320C672x DSP

TMS320C672x is a floating point device family from Texas Instruments that provides high quality audio performance at low prices. The price/performance ratio makes C672x well suited for numerous audio applications. This application note shows how to use C672x to efficiently create delay-based audio effects. The application note explains: • How to leverage the data movement accelerator (dMAX) to move data for delay based applications. • How to implement efficient block processing techniques in delay-based audio effects processing. Along with this application note, an example application is provided that consists of the following four effects: equalizer, chorus, delay, and reverb.
