Audio Basics - How sounds are captured in played in monophonic (mono), two channel (stereo), and multiple channel formats (surround sound).

Analog Audio Formats - Analog signals, their frequency range, analog filtering and noise reduction.

Digital Audio Formats - Digital audio signals, waveform coding, perceptual coding, voice coding.

Capturing Audio - How to capture audio, the optional settings and how they affect the quality of the audio.

Audio Digitization - How to periodically sample audio and convert it into digital signals that represent sound levels, frequencies, and other characteristics of sound.

Audio Compression - How to analyze and represent audio signals in a form that requires less data bits.

Converting Audio Formats - How to convert audio from one format (such as AVI waveform coding) into other formats (such as compressed MP3 or AAC formats).

Multimedia File Formats - How digital audio sequences can be coded and mixed with other media types such as video.

Streaming Digital Audio - How to connect to media sources, request audio programs, and how the systems manage the continuous transfer of media (streaming).

Audio Control Protocols - How audio signals can be setup and controlled.

Digital Audio Quality - How to measure the difference between the original audio signals and the audio signals heard by the listener.
