Method Details

PlayDX7() public static method

Play DX7.

public static PlayDX7 ( Primitive channels ) : Primitive
channels	Primitive	An array of values for each channel (values between 0 and 1, usually 8 channels).
return	Primitive

PlayHarmonics() public static method

Play a user defined wave form as a sum of harmonics.

public static PlayHarmonics ( Primitive frequency, Primitive duration, Primitive harmonics ) : Primitive
frequency	Primitive	Frequency (HZ).
duration	Primitive	Duration (ms). If this is negative then the waveform is repeated (-duration) times.
harmonics	Primitive	Harmonic amplitudes. /// This is an array, where the index is a harmonic multiple of the base frequency (2, 3, etc) and the value is the relative amplitude of the harmonic. /// A square wave can be formed by (https://en.wikipedia.org/wiki/Square_wave): /// For i = 3 To 21 Step 2 /// harmonics[i] = 1/i /// EndFor /// squareWave = LDWaveForm.PlayHarmonics(256,1000,harmonics)
return	Primitive

PlaySineWave() public static method

Play a Sine wave form.

public static PlaySineWave ( Primitive frequency, Primitive duration ) : Primitive
frequency	Primitive	Frequency (HZ).
duration	Primitive	Duration (ms). If this is negative then the waveform is repeated (-duration) times.
return	Primitive

PlaySquareWave() public static method

Play a square wave form.

public static PlaySquareWave ( Primitive frequency, Primitive duration ) : Primitive
frequency	Primitive	Frequency (HZ).
duration	Primitive	Duration (ms). If this is negative then the waveform is repeated (-duration) times.
return	Primitive

PlayWavFile() public static method

Play a wav file.

public static PlayWavFile ( Primitive fileName, Primitive duration ) : Primitive
fileName	Primitive	The *.wav file.
duration	Primitive	Duration (ms). If this is negative then the waveform is repeated (-duration) times.
return	Primitive

PlayWave() public static method

Play a user defined wave form.

public static PlayWave ( Primitive frequency, Primitive duration, Primitive waveform ) : Primitive
frequency	Primitive	Frequency (HZ).
duration	Primitive	Duration (ms). If this is negative then the waveform is repeated (-duration) times.
waveform	Primitive	Form for the repeating wave. /// This is an array, where the index is an increasing relative time (the actual value is normalised to the frequency) and the value is an amplitude (-1 to 1). /// Example of a triangular wave would be "0=-1;1=1;2=-1;"
return	Primitive

Stop() public static method

Stop a playing sound.

public static Stop ( Primitive waveName ) : void
waveName	Primitive	The sound wave name.
return	void
