Summary
The objective of the course is to introduce theory, methods, ans basic psychoacoustics that is needed to understand state-of-the-art techniques used in pro audio and consumer audio, including microphones, surround sound, mixing and audio coding.Content
- Acoustics and audio is covered and the manipulation and processing of audio signals. It is shown how Fourier analysis of a sound field yields the representation of the sound field with plane waves. These and other acoustic insights are used to explain microphone techniques and reproduction of sound fields.
- Psychoacoustics, loudness perception and spatial hearing are covered in detail. The latter is used to motivate stereo and surround mixing and audio playback. Audio playback is put into contex with a detailed coverage of room acoustics.
- The short-time Fourier transform is introduced as a tool for flexible manipulation of audio signals, such as filtering, delaying and other spectral modification. Matrix surround, audio coding, and beamforming are also treated.
