About Superpowered Extension

The Superpowered Extension provides the following audio nodes for a Switchboard SDK audio graph:

AutomaticVocalPitchCorrectionNodeAutomatically adjusts the pitch of vocals to the nearest correct note, ensuring a more accurate and in-tune singing performance.
BitcrusherNodeReduces the audio quality by lowering the bit depth, creating a distinct, gritty, and retro digital sound effect.
ClipperNodeKeeps the amplitude of the audio signal below a maximum level.
CompressorNodeBalances the audio dynamics by reducing the volume of loud sounds and amplifying quieter ones, ensuring a more consistent overall level.
DelayNodeAdds a repeated version of the sound after a short delay, creating an echo-like effect that adds depth and space to the vocals.
EchoNodeCreates a series of reflections of the sound, simulating the effect of sound echoing in a large space, adding depth and resonance.
FilterNodeAlters the frequency content of the sound, allowing certain frequencies to pass through while reducing others, shaping the tonal quality.
FlangerNodeCreates a swirling or swooshing sound by mixing the original audio with a delayed version of itself, resulting in a dynamic and spacey effect.
GateNodePeriodic attenuation of the audio signal.
GuitarDistortionNodeMimics the sound of amplified electric musical instruments.
LimiterNodeBoosts the perceived volume while keeping the maximum level below a limit.
PitchShiftNodeShift the pitch of the sound effect in a ±2 octave range.
ReverbNodeMimics the natural reverberation of sound in a room or hall, adding a sense of space and atmosphere to the vocals.
RollNodeRepeats a small segment of the sound rapidly, creating a stutter or tremolo effect, adding a rhythmic texture to the audio.
SpatializerNodeEnhances the stereo effect by spreading the sound across the stereo field, creating a more immersive and three-dimensional experience.
ThreeBandEQNodeClassic three-band equalizer.
WhooshNodeAdds a sweeping or rushing sound effect, reminiscent of a gust of wind or fast movement, to create a dynamic auditory transition.
