Detailed Description

Represents a MIDI tempo event.

Constructor & Destructor Documentation

TempoEvent() [1/2]

NAudio.Midi.TempoEvent.TempoEvent ( BinaryReader br, int length )

inline

Reads a new tempo event from a MIDI stream.

Parameters

br	The MIDI stream
length	the data length

TempoEvent() [2/2]

NAudio.Midi.TempoEvent.TempoEvent ( int microsecondsPerQuarterNote, long absoluteTime )

inline

Creates a new tempo event with specified settings.

Parameters

microsecondsPerQuarterNote	Microseconds per quarter note
absoluteTime	Absolute time

Member Function Documentation

Clone()

override MidiEvent NAudio.Midi.TempoEvent.Clone ( )

virtual

Creates a new instance of the TempoEvent class that is a copy of the current instance.

Returns

A new instance of the TempoEvent class that is a copy of the current instance.

Reimplemented from NAudio.Midi.MetaEvent.

Export()

override void NAudio.Midi.TempoEvent.Export ( ref long absoluteTime, BinaryWriter writer )

inlinevirtual

Exports the current object to a binary writer, including the microseconds per quarter note.

Parameters

absoluteTime	The absolute time value.
writer	The binary writer to which the object is exported.

This method exports the current object to the specified binary writer, including the microseconds per quarter note. It first calls the base class's Export method to export the base object, then writes the microseconds per quarter note to the writer in little-endian format using three bytes.

Reimplemented from NAudio.Midi.MetaEvent.

ToString()

override string NAudio.Midi.TempoEvent.ToString ( )

inline

Returns a string representation of the object.

Returns

A string containing the object's name, beats per minute, and calculated tempo.

This method returns a formatted string that includes the object's name, beats per minute, and calculated tempo based on the microseconds per quarter note. The tempo is calculated using the formula: 60000000 / microsecondsPerQuarterNote.
