DSPLowpass | Lowpass Filter
DSPNormalize | Noramlize
DSPParameq | Parametric EQ
DSPPitchshift | Pitchshifter
DSPReverb | Reverb
## To use an effect do the following. First create and effect object [we will create an echo for example].
echo = base.sfxManagerList[0].createDsp(base.sfxManagerList[0].DSPEcho)
</td> The effects are constants in the sound manager classes which is why you need to specify "base.sfxManagerList[n].<effect>". Where N is the respective audio manager [0 for Sound, 1 for Music] and <effect> is the respective effect as listed in the table above. Once you have your DSP object you can attach it to a sound.
mySound.addDsp(echo)
</td> and you are ready to go. ## Some Useful DSP commands. At the interactive prompt to get the parameters of a DSP type...
dspEffect.listParameterInfo()
</td> This will list all the DSP parameters and their possible values you can edit. You edit parameters in your code with the following.
dspEffect.setParameter("nameOfParameter", value)
</td> The name of Parameter must be in Quotes. You can retrieve the current parameter with...
dspEffect.getParameter("nameOfParameter")
</td> You can turn a paramter on or off with...
dspEffect.setBypass(n)
</td> Where n is a BOOL You can reset an effect completely to its default values with...
dspEffect.reset(n)
</td> And if you need to detach an effect from a sound use...
mySound.removeDsp(effect)
</td> You can also attach an effect to all the sounds under a Audio Manager with the following...
base.sfxManagerList[n].addDsp(effect)
</td> NOTE!!! An effect attached to a Manager will affect ALL THE SOUNDS under that manager. Otherwise the same commands for DSP apply.
