These formats are sometimes advertised by drivers, e.g. SOF. The format is 3 bytes packed in 32-bit container, with the MSB zeroed out. sample: 0x00123456 S24_LE format: b0 56 b1 34 b2 12 b3 00 S24_BE format: b0 00 b1 12 b2 34 b3 56 I only tested the S24_LE format with the SOF driver, S24_BE was added for symmetry only.
