Function Documentation

get_frame_bytes()

static uint32_t get_frame_bytes ( enum sof_ipc_frame  fmt, uint32_t  channels  )

inlinestatic

Get the byte size of an entire multi-channel audio frame.

Parameters

fmt	Audio frame format enum (enum sof_ipc_frame).
channels	Number of audio channels.

Returns

Total frame size in bytes (sample_bytes * channels).

get_sample_bitdepth()

static uint32_t get_sample_bitdepth ( enum sof_ipc_frame  fmt )

inlinestatic

Get the bit depth of a single audio sample for a given frame format.

Parameters

fmt	Audio frame format enum (enum sof_ipc_frame).

Returns

Number of active audio bits per sample (8, 16, 24, or 32).

get_sample_bytes()

static uint32_t get_sample_bytes ( enum sof_ipc_frame  fmt )

inlinestatic

Get the byte size of a single audio sample for a given frame format.

Parameters

fmt	Audio frame format enum (enum sof_ipc_frame).

Returns

Number of bytes per sample (1, 2, 3, or 4).
