Biquad filter

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

Options:

  • Type list: Filtering algorithm the node is implementing

Parameters:

As every parameter got different meaning depand on filtering algorithm type check parameters' hint in live version for better description.

  • Frequency
  • Detune
  • Q
  • Gain

Code:

Input-output type:

  • Input & Output

Convoler

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

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

Code:

Input-output type:

  • Input & Output

Crossfade

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.

Parameters:

  • Ratio: Crossfade ratio between input one and two. 0 is full first, 100 is full second

Code:

Input-output type:

  • Input & Output

Delay

Records audio signal and then reproduces at a time delay

Parameters:

  • Delay time: Number of seconds by which the signal will be delayed

Code:

Input-output type:

  • Input & Output

Dynamics compressor

Reduces the volume of loud sounds or amplifies quiet sounds, thus reducing or compressing an audio signal's dynamic range

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

Code:

Input-output type:

  • Input & Output

Envelope

Describes how a sound changes over time. When connected to parameter it works like a looper

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

Code:

Input-output type:

  • Output (parameter only)

Equalizer

Adjusting the volume of different frequency bands within an audio signal

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

Code:

Input-output type:

  • Input & Output

Gain

Increases audio signal strength

Parameters:

  • Gain: Multiplication of sound volume

Code:

Input-output type:

  • Input & Output

Stereo panner

Pans an audio stream left or right

Parameters:

  • Pan: Amount of panning to apply. Full left pan is -1 and full right pan is 1

Code:

Input-output type:

  • Input & Output
