Parameter

Description

nWaveType

Type of wave tone.

Supported values are the following:

nSampleRate

Sample rate of the stream, e.g. 44100

nChannels

Number of channels of the audio stream.

Supported values are the following:

fFrequency

Wave tone frequency expressed in Hertz

fAmplitude

Wave tone amplitude.

- value 0.0 means that sound volume is muted

- values higher than 0.0 and lower than 1.0 attenuate the sound volume

- value 1.0 sets the sound at full volume

- values higher than 1.0 amplify the sound volume

nDurationMs

Duration of the wave tone expressed in milliseconds.

nFadeInMs

Duration of the fade-in at the beginning of the wave tone expressed in milliseconds. Set this value to 0 if you don't need to apply a fade-in at the beginning of the audio stream.

nFadeOutMs

Duration of the fade-out at the end of the wave tone expressed in milliseconds. Set this value to 0 if you don't need to apply a fade-out at the end of the audio stream.

Value

Meaning

Negative value

An error occurred (see the LastError property for further error details)

enumErrorCodes.NOERROR (0)

The method call was successful.
