Panda3D 1.3.0 can now make use of FMOD-EX's Audio Effects.

Currently the effects available are...

Panda3D ID	Effect
DSPChorus	Chorus
DSPCompressor	Compression
DSPDistortion	Distortion
DSPEcho	Echo [Delay]
DSPFlange	Flange
DSPHighpass	Highpass Filter
DSPItecho	Echo [For Mod/Tracker Files]
DSPItlowpass	Lowpass Filter [For Mod/Tracker Files]
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].

</td>

echo = base.sfxManagerList[0].createDsp(base.sfxManagerList[0].DSPEcho)

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.

</td>

mySound.addDsp(echo)

and you are ready to go.

Some Useful DSP commands.

At the interactive prompt to get the parameters of a DSP type...

</td>

dspEffect.listParameterInfo()

This will list all the DSP parameters and their possible values you can edit.

You edit parameters in your code with the following.

</td>

dspEffect.setParameter("nameOfParameter", value)

The name of Parameter must be in Quotes.

You can retrieve the current parameter with...

</td>

dspEffect.getParameter("nameOfParameter")

You can turn a paramter on or off with...

</td>

dspEffect.setBypass(n)

Where n is a BOOL

You can reset an effect completely to its default values with...

</td>

dspEffect.reset(n)

And if you need to detach an effect from a sound use...

</td>

mySound.removeDsp(effect)

You can also attach an effect to all the sounds under a Audio Manager with the following...

</td>

base.sfxManagerList[n].addDsp(effect)

NOTE!!! An effect attached to a Manager will affect ALL THE SOUNDS under that manager.

Otherwise the same commands for DSP apply.
