Declared in	ORKAudioGenerator.h ORKAudioGenerator.m

Overview

The ORKAudioGenerator class represents an audio tone generator.

Returns the peak audio volume being currently played, in decibels (dB).

- (double)volumeInDecibels

The current audio volume in decibels.

ORKAudioGenerator.h

Returns the peak audio volume amplitude being currently played (from 0 to 1).

- (double)volumeAmplitude

The current audio volume amplitude.

ORKAudioGenerator.h

Plays a tone at a specific frequency in stereo.

- (void)playSoundAtFrequency:(double)frequency

`frequency`	The audio frequency in hertz.

The sound is a “pure” sinusoid tone.

ORKAudioGenerator.h

Plays a tone at a specific frequency on a specific channel, with a fade-in effect.

- (void)playSoundAtFrequency:(double)frequency onChannel:(ORKAudioChannel)channel fadeInDuration:(NSTimeInterval)duration

`frequency`	The audio frequency in hertz.
`channel`	The audio channel (left or right).
`duration`	The fade-in duration.

The sound is a “pure” sinusoid tone. The fade-in effect is applied linearly for the peak amplitude, from a 0 to 1 factor.

ORKAudioGenerator.h

Stops the audio being played.

- (void)stop
