Detailed Description

A class that handles tempo syncing.

All methods are static and it holds no data, so you have to get the host bpm before you can use this class.

You can use the slider mode TempoSync, which automatically maps the slider values to the tempo indexes and shows the corresponding text representation.

If the supplied hostTempo is invalid (= 0.0), a default tempo of 120.0 is used.

Member Function Documentation

static Tempo getTempoIndex ( const String &  t )

inlinestatic

Returns the index of the tempo with the name 't'.

static Tempo getTempoIndexForTime ( double  currentBpm, double  milliSeconds  )

inlinestatic

Returns the next Tempo index for the given time.

This is not a super fast operation, but it helps with dealing between the two realms.

static float getTempoInHertz ( double  hostTempoBpm, Tempo  t  )

inlinestatic

Returns the tempo as frequency (in Hertz).

static float getTempoInMilliSeconds ( double  hostTempoBpm, Tempo  t  )

inlinestatic

Returns the time for the specified tempo in milliseconds.

static int getTempoInSamples ( double  hostTempoBpm, double  sampleRate, Tempo  t  )

inlinestatic

Returns the sample amount for the specified tempo.

static String getTempoName ( int  t )

inlinestatic

Returns the name of the tempo with the index 't'.

static void initTempoData ( )

inlinestatic

Fills the internal arrays.
