What does Audio bit depth mean?
Audio bit depth describes the number of bits used to represent each sample value in a relevant digital representation. It relates to quantisation precision, not directly to the loudness setting or the number of speakers.
Why it matters
Compressed audio formats can use coding structures that are not meaningfully summarised by a simple PCM bit-depth label. Output conversion also cannot recreate information already lost in a source. For viewers, codec compatibility, correct channel handling and stable synchronisation are more actionable than forcing an elaborate system setting without understanding the playback chain. Keep the original configuration documented before experimenting.
A practical example
A receiver displaying a high-bit-depth PCM output does not prove the programme began as a lossless recording of the same specification. The player may have decoded and converted a compressed source, so distinguish the output representation from the original delivery format.
