Class MusicalTime

Namespace

NAudio.Sequencing

Assembly

NAudio.Core.dll

Constants and helpers for the canonical tick resolution used by the sequencing primitives. All ticks in ITempoMap, EventTimeline<T>, TimeSignatureMap, and Transport are at CanonicalPpq, regardless of the PPQ in any source file (e.g. a MIDI file). External PPQs must be rescaled at the ingestion boundary.

Fields

CanonicalPpq

The canonical pulses-per-quarter-note used by the sequencing layer. 960 divides cleanly into common subdivisions (8ths, 16ths, 32nds, triplets) and matches the default of most DAWs.

public const int CanonicalPpq = 960

Field Value

int

Properties

QuarterTripletTicks

Ticks per quarter-note triplet at the canonical PPQ.

public static long QuarterTripletTicks { get; }

Property Value

long

Methods

RescaleFromPpq(long, int)

Converts a tick value from an external PPQ (e.g. a MIDI file's DeltaTicksPerQuarterNote) to the canonical PPQ used by the sequencing layer. Apply at the ingestion boundary to event absolute times, tempo events, and time-signature events alike.

public static long RescaleFromPpq(long fileTick, int fileDeltaTicksPerQuarterNote)

Parameters

fileTick long

fileDeltaTicksPerQuarterNote int

Returns

long

TicksPerDivision(int)

Returns the number of canonical ticks per note of the given musical division (4 = quarter, 8 = eighth, 16 = sixteenth, etc).

public static long TicksPerDivision(int division)

Parameters

division int

A power-of-two note division (1 = whole, 4 = quarter, 16 = sixteenth).

Returns

long
