- Companding
- Speech Synthesis and Recognition
- Nonlinear Audio Processing
Audio processing covers many diverse fields, all involved in presenting sound
to human listeners. Three areas are prominent: (1) high fidelity music
reproduction, such as in audio compact discs, (2) voice
telecommunications, another name for telephone networks, and (3) synthetic
speech, where computers generate and recognize human voice patterns. While
these applications have different goals and problems, they are linked by a common
umpire: the human ear. Digital Signal Processing has produced revolutionary changes in
these and other areas of audio processing.
