Biquad filter

Description:
  • Second order IIR filter. It is high enough order to be useful on its own, and - because of coefficient sensitivities in higher order filters - the biquad is often used as the basic building block for more complex filters
Input-output type:
  • Input & Output
Options:
  • Type list: Filtering algorithm the node is implementing
As every parameter got different meaning depand on filtering algorithm type check parameters' hint in live version for better description.
Parameters:
  • Frequency
  • Detune
  • Q
  • Gain

Convoler

Description:
  • Takes the sonic properties of a real world object (acoustic space, analogue gear etc) and applys those to a given signal to mimic the sound of the original device/space
Input-output type:
  • Input & Output
Options:
  • IR list: Different types of preloaded IR
  • Normalizer: Apply a fixed amount of gain to audio so that the highest peak is set at the highest acceptable recording level

Crossfade

Description:
  • Makes smooth transition between the two inputs. If more inputs will be added first one will be dropped and replaced by second. The new input will become second track.
Input-output type:
  • Input & Output
Parameters:
  • Ratio: Crossfade ratio between input one and two. 0 is full first, 100 is full second

Delay

Description:
  • Records audio signal and then reproduces at a time delay
Input-output type:
  • Input & Output
Parameters:
  • Delay time: Number of seconds by which the signal will be delayed

Dynamics compressor

Description:
  • Reduces the volume of loud sounds or amplifies quiet sounds, thus reducing or compressing an audio signal's dynamic range
Input-output type:
  • Input & Output
Parameters:
  • Threshold: The level at which a dynamics processing unit will begin to change the gain of the incoming signal
  • Knee: Determines how abruptly or gradually compression begins once the sound level crosses the threshold
  • Ratio: The amount of gain reduction. Input level over this amount dB will be reduced by 1dB over the threshold
  • Attack: The point where the sound begins and increases in volume to its peak
  • Release: The rate at which the volume drops to zero as the sound stops playing

Envelope

Description:
  • Describes how a sound changes over time. When connected to parameter it works like a looper
Input-output type:
  • Output (parameter only)
Parameters:
  • Delay: Number of second by which envelope start will be delayed
  • Attack: Time taken for initial run-up of level from nil to peak, beginning when the key is pressed
  • Decay: Time taken for the subsequent run down from the attack level to the designated sustain level
  • Sustain: Level during the main sequence of the sound's duration, until the key is released
  • Hold: Number of second by which sound will be played on the sustain level
  • Release: Time taken for the level to decay from the sustain level to zero after the key is released

Equalizer

Description:
  • Adjusting the volume of different frequency bands within an audio signal
Input-output type:
  • Input & Output
Parameters:
  • XXXHZ: Boost or an attenuation of frequency XXXHz
  • Band width: Controls the width of the frequency band. The greater the value, the larger the frequency band

Gain

Description:
  • Increases audio signal strength
Input-output type:
  • Input & Output
Parameters:
  • Gain: Multiplication of sound volume

Stereo panner

Description:
  • Pans an audio stream left or right
Input-output type:
  • Input & Output
Parameters:
  • Pan: Amount of panning to apply. Full left pan is -1 and full right pan is 1
