uint16_t music_chunk::bit_rate

current bit rate of the source file

Definition at line 63 of file chunk.h.

char music_chunk::data[CHUNK_SIZE]

the data (probably PCM)

Definition at line 90 of file chunk.h.

uint16_t music_chunk::length

number of bytes stored in this chunk

Definition at line 60 of file chunk.h.

float music_chunk::mix_ratio

The current mix ratio for cross-fading: 1.0 means play 100% of this chunk, 0.0 means play 100% of the "other" chunk.

Definition at line 57 of file chunk.h.

struct music_chunk* music_chunk::next

the next chunk in a linked list

Definition at line 45 of file chunk.h.

struct music_chunk* music_chunk::other

An optional chunk which should be mixed into this chunk.

This is used for cross-fading.

Definition at line 51 of file chunk.h.

struct replay_gain_info music_chunk::replay_gain_info

Replay gain information associated with this chunk.

Only valid if the serial is not 0.

Definition at line 80 of file chunk.h.

unsigned music_chunk::replay_gain_serial

A serial number for checking if replay gain info has changed since the last chunk.

The magic value 0 indicates that there is no replay gain info available.

Definition at line 87 of file chunk.h.

struct tag* music_chunk::tag

An optional tag associated with this chunk (and the following chunks); appears at song boundaries.

The tag object is owned by this chunk, and must be freed when this chunk is deinitialized in music_chunk_free()

float music_chunk::times

the time stamp within the song
