Contraptions Guide

This section includes Help Files for each of AudioMulch's contraptions. Below is a comprehensive list of the contraptions, grouped by category, and a brief explanation of what each contraption does. To find out more information about any contraption, click on the links in the list.

Note: To directly access a contraption's Help File page while using the program, click on the ? button on the title bar of the contraption's Property Editor.

Input/Output

*FilePlayer
Plays one or more multichannel sound files with multitrack synchronization.
*FileRecorder
Records one or more multichannel sound files with multitrack synchronization.
SoundIn
Inputs live sound from the audio interface or plays a sound file.
SoundOut
Outputs sound to the audio interface. Optionally, records sound to a file.
AuxIn / AuxOut
Additional live audio interface inputs and outputs for multichannel and surround sound.
MidiIn / MidiOut
Inputs or outputs live MIDI to or from a MIDI interface or other software application. (For use with VST and Audio Unit plugins).
FilePlayer
Plays a stereo sound file.
FileRecorder
Records a stereo sound file.

Signal Generators

Arpeggiator
A synthesizer and tone generator that plays arpeggios.
Bassline
Synthesizes and sequences a melody or chops up and filters a sound input.
LoopPlayer
Plays a looped sound file synchronized to the beat or stretches a loop for pitch and time distortion effects.
Drums
Plays back samples sequenced in repetitive patterns, sometimes used as a drum machine.
BubbleBlower
Randomly chops up and scrambles sound files to create fractured or smooth textures (granular synthesis).
RissetTones
Synthesizes a continuously ascending or descending tone.
10Harmonics
Synthesizes a harmonic tone by controlling the amplitude of the first 10 harmonics (additive synthesis).
TestGen
Generates tones: a sine wave or noise.

Effects

PulseComb
Creates a pulse-like chopping of sound input and a pitch-shifting effect.
DLGranulator
Randomly chops up and scrambles live sound to create fractured or smooth textures (granular synthesis).
SDelay
Applies stereo delays, repetitive echo and stereo ping-pong effects.
CanonLooper
Captures sound and loops it in multiple layers to create musical canons (rounds).
LiveLooper
Captures and controls up to 16 tracks of looping sound.
DigiGrunge
Applies digital distortion effects (bit depth reduction, sample rate decimation).
Shaper
Adds distortion with direct control over distortion harmonics (Chebychev waveshaping).
SSpat
Creates the illusion of sound moving in space in looped paths using panning and doppler shift.
NastyReverb
A digital reverb effect.
Flanger
Creates a sweeping, whooshing filter effect with a metallic, ringing sound.
Phaser
Creates a sweeping, whooshing filter effect with a hollow, resonant sound.
FrequencyShifter
Shifts harmonics to create metallic sounds, or sweeping phaser-like effects when used with subtle settings and feedback.
RingAM
Adds shifted frequencies, and can produce metallic sounds (ring and amplitude modulation).
SChorus
Creates a sweeping, detuned thickening and stereo-widening chorus effect.

Filters

Nebuliser
Randomly chops up and scrambles live sound with random filtering to create watery sounds (filtered granular synthesis).
SouthPole
Applies resonant filtering and amplitude-chopping effects controlled by rhythmic patterns or sound input (envelope following and pattern controlled ADSR filtering and amplitude gating).
RissetFilters
Applies continuously ascending or descending sweeping bandpass filters - a filtering version of RissetTones.
*ParaEQ
Equalizer filter boosts or cuts certain frequencies (parametric with high and low shelf, and two sweepable mid bands). (M=Mono, S=Stereo).
5Combs
Filters sounds through tuned comb filters that sound like resonating strings.

Dynamics

*Limiter
Limits the peak level of a sound to avoid harsh clipping distortion.
*Compressor
Controls the level of a sound to reduce dynamic range or shape transients.
*NoiseGate
Allows loud sounds to pass while suppressing quiet ones (or vice-versa).

Mixers

Matrix
Switches and combines different input channels to different outputs.
Crossfader
Smoothly mixes and fades from one stereo input to another.
Frosscader
Smoothly fades a stereo input between two different stereo outputs.
Invert
Inverts the polarity of an audio input (useful for stereo wide illusion and other tricks).
*Gain
Volume control knob for one or more channels (M=Mono (1), S=Stereo (2), Q=Quad (4), O=Oct (8)).
M*Mixer
Mono mixers with volume control for each input.
P*Mixer
Stereo mixers with mono inputs and a pan control for each input.
S*Mixer
Stereo mixers with volume control for each stereo input pair.

Buses

M*Bus
Mixes mono signals without volume control. Useful as a patch-point for complex patches. (Provided for backward compatibility).
S*Bus
Mixes stereo signals without volume control. Useful as a patch-point for complex patches. (Provided for backward compatibility).

Plugins

As well as its own contraptions, AudioMulch supports the industry standard VST (Virtual Studio Technology) and VSTi (also known as VST2) plugin formats, and on Macintosh, Apple's Audio Unit plugin format. This gives you access to a large number of third-party effects and instruments to expand AudioMulch.

VST Plugins
Third-party plugins you install on your computer to provide additional effects and instruments.
Audio Unit Plugins (Macintosh only)
Third-party plugins you install on your computer to provide additional effects and instruments.
