for more information about audio signal processing

Audio signal processing, sometimes referred to as audio processing, is the intentional alteration of auditory signals, or sound. As audio signals may be electronically represented in either digital or analog format, signal processing may occur in either domain. Analog processors operate directly on the electrical signal, while digital processors operate mathematically on the binary representation of that signal.

I am doing my project in Matlab which involves audio signal processing.I need reference material.It seems to me that project content could be similar to the dsp project idea given in site, "rr. Analyzing equalizer effects for a speech signals".Where can I find the reference material?
