3/// A complete uncompressed-audio format description.
4///
5/// Unlike a `(sample_rate, channels)` tuple, this also carries the sample
6/// representation, so it can be passed directly from a hardware endpoint
7/// such as `WasapiCaptureSource`/`WasapiRenderer` to an
8/// [`crate::elements::AudioResampler`]/[`crate::elements::SwAudioEncoder`]
9/// without guessing either one. Kept directly under `elements` rather than
10/// under any one of those (same reasoning as
11/// [`crate::elements::RtspTransport`]/[`crate::elements::VideoFormat`]'s own
12/// placement): it crosses source/filter/sink, not owned by any single one.
