Detailed Description

Interface to control the active sound effects (echo, reverb,...) of an ISound object, a playing sound.

Sound effects such as chorus, distorsions, echo, reverb and similar can be controlled using this. An instance of this interface can be obtained via ISound::getSoundEffectControl(). The sound containing this interface has to be started via ISoundEngine::play2D() or ISoundEngine::play3D() with the flag enableSoundEffects=true, otherwise no acccess to this interface will be available. For the DirectSound driver, these are effects available since DirectSound8. For most effects, sounds should have a sample rate of 44 khz and should be at least 150 milli seconds long for optimal quality when using the DirectSound driver. Note that the interface pointer is only valid as long as the ISound pointer is valid. If the ISound pointer gets dropped (IVirtualRefCounted::drop()), the ISoundEffects may not be used any more.

fDepth Percentage by which the delay time is modulated by the low-frequency oscillator, in hundredths of a percentage point. Minimal Value:0, Maximal Value:100.0f;
fFeedback Percentage of output signal to feed back into the effect's input. Minimal Value:-99, Maximal Value:99.0f;
fFrequency Frequency of the LFO. Minimal Value:0, Maximal Value:10.0f;
sinusWaveForm True for sinus wave form, false for triangle.
fDelay Number of milliseconds the input is delayed before it is played back. Minimal Value:0, Maximal Value:20.0f;
lPhase Phase differential between left and right LFOs. Possible values: -180, -90, 0, 90, 180
Returns:
Returns true if successful.

) [pure virtual]

Enables the Distortion sound effect or adjusts its values.

Distortion is achieved by adding harmonics to the signal in such a way that, If this sound effect is already enabled, calling this only modifies the parameters of the active effect. as the level increases, the top of the waveform becomes squared off or clipped.

Parameters:

fEdge Percentage of distortion intensity. Minimal Value:0, Maximal Value:100;
fPostEQCenterFrequency Center frequency of harmonic content addition. Minimal Value:100, Maximal Value:8000;

bool  triangleWaveForm = true,
ik_f32  fDelay = 2,
ik_s32  lPhase = 0 
) [pure virtual]

Enables the Flanger sound effect or adjusts its values.

Flange is an echo effect in which the delay between the original signal and its echo is very short and varies over time. The result is sometimes referred to as a sweeping sound. The term flange originated with the practice of grabbing the flanges of a tape reel to change the speed. If this sound effect is already enabled, calling this only modifies the parameters of the active effect.

Parameters:
fWetDryMix Ratio of wet (processed) signal to dry (unprocessed) signal. Minimal Value:0, Maximal Value:100.0f;
fDepth Percentage by which the delay time is modulated by the low-frequency oscillator, in hundredths of a percentage point. Minimal Value:0, Maximal Value:100.0f;
fFeedback Percentage of output signal to feed back into the effect's input. Minimal Value:-99, Maximal Value:99.0f;
fFrequency Frequency of the LFO. Minimal Value:0, Maximal Value:10.0f;
triangleWaveForm True for triangle wave form, false for square.
fDelay Number of milliseconds the input is delayed before it is played back. Minimal Value:0, Maximal Value:20.0f;
lPhase Phase differential between left and right LFOs. Possible values: -180, -90, 0, 90, 180
Returns:
Returns true if successful.
