SoundComposer.ItemSlidingWaveToneLimitsSet method

Previous pageReturn to chapter overviewNext page

Remarks

 

Modifies initial and final frequencies and amplitudes used to generate a specific sliding wave tone item. Current frequencies and/or amplitudes can be obtained through the SoundComposer.ItemSlidingWaveToneLimitsGet method.

 

For further details about sound composing see the the SoundComposer object and the How to compose a sound tutorial.

 

 

Syntax

 

[Visual Basic]

control.SoundComposer.ItemSlidingWaveToneLimitsSet (

nUniqueId as Long,

fFrequencyStart as Single,

fFrequencyEnd as Single,

fAmplitudeStart as Single,

fAmplitudeEnd as Single

) as enumErrorCodes


 

[C++]

short control.SoundComposer.ItemSlidingWaveToneLimitsSet (

long nUniqueId,

float fFrequencyStart,

float fFrequencyEnd,

float fAmplitudeStart,

float fAmplitudeEnd

);


 

Parameter

Description

 

 

nUniqueId

The unique identifier of the element previously returned by the call to the SoundComposer.ItemSlidingWaveToneAdd method.

fFrequencyStart

Initial wave tone frequency expressed in Hertz, e.g. 700

fFrequencyEnd

Final wave tone frequency expressed in Hertz, e.g. 1000

fAmplitudeStart

Initial wave tone amplitude.

- value 0.0 means that sound volume is muted

- values higher than 0.0 and smaller than 1.0 attenuates the sound volume

- value 1.0 sets the sound at full volume

- values higher than 1.0 amplifies the sound volume

fAmplitudeEnd

Final wave tone amplitude.

- value 0.0 means that sound volume is muted

- values higher than 0.0 and smaller 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
