AU Audio Format Reader and Writer

A reader and writer for the AU audio format. AU is made of a small header, an optional description field and sample data.

AU can store uncompressed integer or floating point sample data. It can also store compressed sample data. This crate supports uncompressed sample data and μ-law or A-law compressed sample data.

The AU header contains the length of the sample data. The header can also indicate that the length is unknown, which means that audio data should be read until the end of the stream. This enables file lengths over 4 gigabytes and streams with an infinite length.

Provided functionality:

• AuReader reads the AU audio format, typically from a file.
• AuWriter writes the AU audio format, typically to a file or a stream.
• AuStreamParser parses the AU audio format and sends events to a callback. Useful for reading infinite AU streams.

Terminology: The term info is used to mean header data (made of channel count, sample rate, …). The term description is used to mean the description / info / annotation data field.
