Applications in Audio Signal Processing
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.
Difference b/w Discrete and Digital Signal
Discrete Signals : Obtained by sampling the analog signal at discrete instants of time. However the magnitude of the discrete signals is same as that of the analog signal at that point in time.
Digital Signal : When the magnitude of the discrete signal is quantized to the nearest integer, we get a digital signal.
