norm~norm~ is an audio signal normalizer that adjusts the input signal's level to a specified decibel full scale (dBFS) value.
duck~ The duck~ object is an audio dynamics processor that automatically reduces the volume of an input signal when a separate control signal exceeds a defined threshold.
compress~ The compress~ object is an audio compressor that attenuates an input signal when its amplitude exceeds a specified threshold.
vca.m~ The vca.m~ object functions as a mono Voltage Controlled Amplifier (VCA), allowing dynamic control over an audio signal's level via a Control Voltage (CV) input.
clip~ The cyclone/clip~ object constrains an input audio signal to a specified minimum and maximum range.
fluid.bufthresh The fluid.bufthresh object processes a source buffer by replacing all values below a specified threshold with zero.
expand~expand~ is an audio expander that attenuates an input signal when its level falls below a specified threshold.
level~ The level~ object adjusts the gain of an incoming signal in decibels (dB).
drown~ The drown~ object performs spectral noise floor manipulation on audio signals using FFT.
noisegate~noisegate~ is a noise gate abstraction that passes audio signals only when their RMS value exceeds a specified threshold (in dBFS).
dbgain~ The dbgain~ object adjusts the gain of an audio signal in decibels.
limiter~ The limiter~ object in Pure Data functions as an audio dynamics processor, preventing signals from exceeding a specified output level to avoid clipping.
pvcompand~pvcompand~ is a spectral compander that either expands or compresses the dynamic range of audio signals in the frequency domain.
flunson The flunson object rescales audio amplitudes according to the Fletcher-Munson curves.
