◆ m_byte_rate

uint32_t WAV_HEADER::m_byte_rate

Definition at line 73 of file wave.h.

◆ m_fmt_chunk_size

uint32_t WAV_HEADER::m_fmt_chunk_size

Should be 16 for PCM This is the size of the rest of the chunk size which follows this number.

Definition at line 69 of file wave.h.

◆ m_fmt_header

std::array<uint8_t, 4> WAV_HEADER::m_fmt_header

RIFF Format Header: Contains "fmt " including trailing space (0x666d7420 big-endian form).

Definition at line 68 of file wave.h.

◆ m_num_channels

uint16_t WAV_HEADER::m_num_channels

Number of channels 1...n (1: mono, 2: stereo/dual channel;...)

Definition at line 71 of file wave.h.

◆ m_riff_header

std::array<uint8_t, 4> WAV_HEADER::m_riff_header

RIFF Header: Contains the letters "RIFF" in ASCII form (0x52494646 big-endian form).

Definition at line 52 of file wave.h.

◆ m_sample_alignment

uint16_t WAV_HEADER::m_sample_alignment

num_channels * bit_depth / 8

Definition at line 74 of file wave.h.

◆ m_sample_rate

uint32_t WAV_HEADER::m_sample_rate

8000, 44100, etc.

Definition at line 72 of file wave.h.

◆ m_wav_size

uint32_t WAV_HEADER::m_wav_size

Size of the wav portion of the file, which follows the first 8 bytes (File size - 8).
36 + fmt_chunk_size, or more precisely:
4 + (8 + fmt_chunk_size) + (8 + fmt_chunk_size) This is the size of the rest of the chunk following this number. This is the size of the entire file in bytes minus 8 bytes for the two fields not included in this count: riff_header and wav_size.
