carb::audio::alignBytesToFrameFloor¶

constexpr size_t carb::audio::alignBytesToFrameFloor(size_t bytes, size_t channels, SampleFormat format)¶

aligns a byte count to a frame boundary for an audio data format.

Parameters

bytes – [in] the byte count to align to a frame boundary. This will be aligned to the previous frame boundary if it is not already aligned.
channels – [in] the number of channels in the audio data format.
format – [in] the sample format of the data. This must be a PCM sample format.

Returns

the requested byte count aligned to the previous frame boundary if it is not already aligned.

Returns
