Description

struct { char chunk_id[4]; uint32_t chunk_size; char chunk_format[4]; }

Canonical WAVE format starts with the RIFF header.

struct { char subchunk_id[4]; uint32_t subchunk_size; uint16_t audio_format; uint16_t num_of_channels; uint32_t sample_rate; uint32_t byte_rate; uint16_t block_align; uint16_t bits_per_sample; }

The "fmt " subchunk describes the sound data's format.

struct { char subchunk_id[4]; uint32_t subchunk_size; int16_t data[0]; }

The "data" subchunk contains the size of the data and the actual sound.
