public class RekordboxAnlz
extends io.kaitai.struct.KaitaiStruct

These files are created by rekordbox when analyzing audio tracks to facilitate DJ performance. They include waveforms, beat grids (information about the precise time at which each beat occurs), time indices to allow efficient seeking to specific positions inside variable bit-rate audio streams, and lists of memory cues and loop points. They are used by Pioneer professional DJ equipment. The format has been reverse-engineered to facilitate sophisticated integrations with light and laser shows, videos, and other musical instruments, by supporting deep knowledge of what is playing and what is coming next through monitoring the network communications of the players.

static class	RekordboxAnlz.CueExtendedEntry	A cue extended list entry.
static class	RekordboxAnlz.CueExtendedTag	A variation of cue_tag which was introduced with the nxs2 line, and adds descriptive names.
static class	RekordboxAnlz.CueListType
static class	RekordboxAnlz.CueTag	Stores either a list of ordinary memory cues and loop points, or a list of hot cues and loop points.

static class	RekordboxAnlz.UnknownTag
static class	RekordboxAnlz.VbrTag	Stores an index allowing rapid seeking to particular times within a variable-bitrate audio file.
static class	RekordboxAnlz.WaveColorPreviewTag	A larger, colorful waveform preview image suitable for display above the touch strip for jumping to a track position on newer high-resolution players.
static class	RekordboxAnlz.WaveColorScrollTag	A larger, colorful waveform image suitable for scrolling along as a track plays on newer high-resolution hardware.
static class	RekordboxAnlz.WavePreviewTag	Stores a waveform preview image suitable for display above the touch strip for jumping to a track position.
static class	RekordboxAnlz.WaveScrollTag	A larger waveform image suitable for scrolling along as a track plays.
