This is the revision field used with audren. This controls which format is used for the data used with [[#IAudioRenderer|IAudioRenderer]] RequestUpdate*, etc.
This is "nn::audio::FinalOutputRecorderBuffer".
 
Bitmask 0xFFFFFF == 0x564552 (REV) is used for determining whether the user-process is using NX-platform. On Ounce, the revision value is identical except that bitmask 0xFFFFFF is 0x764552 (REv).

This is the revision field used with audren. This controls which format is used for the data used with [[#IAudioRenderer|IAudioRenderer]] RequestUpdate*, etc.
 
Bitmask 0xFFFFFF == 0x564552 (REV) is used for determining whether the user-process is using NX-platform. On Ounce, the revision value is identical except that bitmask 0xFFFFFF is 0x764552 (REv). The latter is only supported on S2.
 
GetWorkBufferSize/OpenAudioRenderer validate the revision, with an error being thrown if invalid (unrecognized top-byte / low-bitmask is unrecognized).
