Functions
ZRegion *	audio_region_new (const int pool_id, const char *filename, bool read_from_pool, const float *frames, const unsigned_frame_t nframes, const char *clip_name, const channels_t channels, BitDepth bit_depth, const Position *start_pos, unsigned int track_name_hash, int lane_pos, int idx_inside_lane, GError **error)
	Creates a region for audio data.
AudioClip *	audio_region_get_clip (const ZRegion *self)
	Returns the audio clip associated with the Region.
void	audio_region_set_clip_id (ZRegion *self, int clip_id)
	Sets the clip ID on the region and updates any references.
WARN_UNUSED_RESULT bool	audio_region_replace_frames (ZRegion *self, float *frames, unsigned_frame_t start_frame, unsigned_frame_t num_frames, bool duplicate_clip, GError **error)
	Replaces the region's frames from start_frames with frames.
REALTIME HOT NONNULL void	audio_region_fill_stereo_ports (ZRegion *self, const EngineProcessTimeInfo *const time_nfo, StereoPorts *stereo_ports)
	Fills audio data from the region.
float	audio_region_detect_bpm (ZRegion *self, GArray *candidates)
bool	audio_region_validate (ZRegion *self, double frames_per_tick)
	Sanity checking.
bool	audio_region_fix_positions (ZRegion *self, double frames_per_tick)
	Fixes off-by-one rounding errors when changing BPM or sample rate which result in the looped part being longer than there are actual frames in the clip.
void	audio_region_free_members (ZRegion *self)
	Frees members only but not the audio region itself.
