|
Remarks
Generates a noise audio stream.
For further details about sound generation see the SoundGeneratorMan class and the How to generate wave tones, noises, DTMF tones and text to speech tutorial.
Syntax
[Visual Basic] Public Function NoiseGenerate ( nNoiseType as enumSoundGenNoiseTypes, nSampleRate as Int32, nChannels as Int32, fReserved as Single, fAmplitude as Single, nDurationMs as Int32, nFadeInMs as Int32, nFadeOutMs as Int32 ) as enumErrorCodes |
[C#] public enumErrorCodes NoiseGenerate ( enumSoundGenNoiseTypes nNoiseType, Int32 nSampleRate, Int32 nChannels, float fReserved, float fAmplitude, Int32 nDurationMs, Int32 nFadeInMs, Int32 nFadeOutMs ); |
[C++] public: enumErrorCodes NoiseGenerate ( enumSoundGenNoiseTypes nNoiseType, Int32 nSampleRate, Int32 nChannels, float fReserved, float fAmplitude, Int32 nDurationMs, Int32 nFadeInMs, Int32 nFadeOutMs ); |
Parameter |
Description |
||||||||||||
|
|
||||||||||||
nNoiseType |
Type of noise. 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:
|
||||||||||||
fReserved |
Reserved for future uses, set this parameter to 0 |
||||||||||||
fAmplitude |
Noise 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 noise expressed in milliseconds. |
||||||||||||
nFadeInMs |
Duration of the fade-in at the beginning of the noise 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 noise 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. |
