It is prudent here to note that speech is a very specific type of audio signal, and that many speech processing methods exploit speech’s specific nature. Wideband audio coders are able to process all audio, whereas most of the techniques in this book refer more toward speech in particular. Perhaps reflecting the interests of the authors, this book’s approach to the …
