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.

Modifier and Type	Class	Description
static class	RekordboxAnlz.BeatGridBeat	Describes an individual beat in a beat grid.
static class	RekordboxAnlz.BeatGridTag	Holds a list of all the beats found within the track, recording their bar position, the time at which they occur, and the tempo at that point.
static class	RekordboxAnlz.CueEntry	A cue list entry.
static class	RekordboxAnlz.CueEntryStatus
static class	RekordboxAnlz.CueEntryType
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.PathTag	Stores the file path of the audio file to which this analysis applies.

static class	RekordboxAnlz.SongStructureEntry	A song structure entry, represents a single phrase.
static class	RekordboxAnlz.SongStructureTag	Stores the song structure, also known as phrases (intro, verse, bridge, chorus, up, down, outro).
static class	RekordboxAnlz.TaggedSection	A type-tagged file section, identified by a four-byte magic sequence, with a header specifying its length, and whose payload is determined by the type tag.
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.
