## Detailed Description

FLAC frame header structure. (c.f. format specification)

## Member Data Documentation

## ◆ blocksize

uint32_t FLAC__FrameHeader::blocksize

The number of samples per subframe.

## ◆ sample_rate

uint32_t FLAC__FrameHeader::sample_rate

The sample rate in Hz.

## ◆ channels

uint32_t FLAC__FrameHeader::channels

The number of channels (== number of subframes).

## ◆ channel_assignment

FLAC__ChannelAssignment FLAC__FrameHeader::channel_assignment

The channel assignment for the frame.

## ◆ bits_per_sample

uint32_t FLAC__FrameHeader::bits_per_sample

The sample resolution.

## ◆ number_type

FLAC__FrameNumberType FLAC__FrameHeader::number_type

The numbering scheme used for the frame. As a convenience, the decoder will always convert a frame number to a sample number because the rules are complex.

## ◆ number

union { ... } FLAC__FrameHeader::number

The frame number or sample number of first sample in frame; use the number_type value to determine which to use.

## ◆ crc

FLAC__uint8 FLAC__FrameHeader::crc

CRC-8 (polynomial = x^8 + x^2 + x^1 + x^0, initialized with 0) of the raw frame header bytes, meaning everything before the CRC byte including the sync code.
