Audio Utilities

Signal routing, mixing, and conversion utilities for audio signals.

Level & Mixing

Gain

Amplifies or attenuates a mono audio signal.

Parameter	Range	Default	Description
Gain	dB	0 dB	Gain amount

Input: Audio In Output: Audio Out

Gain Stereo

Amplifies or attenuates a stereo audio signal.

Parameter	Range	Default	Description
Gain	dB	0 dB	Gain amount (applied to both channels)

Inputs: Audio In L, Audio In R Outputs: Audio Out L, Audio Out R

Mix 2

Mixes two audio signals together with a crossfade control.

Parameter	Range	Default	Description
Mix	0.0 - 1.0	0.5	Crossfade between A and B. 0 = A only, 1 = B only

Inputs: Audio A, Audio B Output: Mixed Audio

Audio Add

Sums two audio signals.

Inputs: Audio A, Audio B Output: A + B

Audio Multiply

Multiplies two audio signals (ring modulation effect).

Inputs: Audio A, Audio B Output: A x B

Signal Processing

Invert

Flips the polarity of the audio signal (phase invert).

Input: Audio Output: Inverted Audio

DC Offset

Adds or removes DC offset from a signal.

Parameter	Range	Default	Description
Offset	—	0.0	DC offset amount to add

Audio Clamp

Limits the signal to a specified range.

Parameter	Range	Default	Description
Min	—	-1.0	Minimum allowed value
Max	—	1.0	Maximum allowed value

Audio Abs

Absolute value of the signal (full-wave rectification).

Input: Audio Output: |Audio|

Smooth

Smooths rapid changes in a signal. Low-pass filter for control signals.

Parameter	Range	Default	Description
Time	ms	—	Smoothing time
Rise	ms	—	Rise smoothing
Fall	ms	—	Fall smoothing

Signal Gate

Passes or blocks audio based on a control signal.

Inputs: Audio, Gate (> 0 passes audio) Output: Gated Audio

---

Routing

Audio Pass

Passes audio through unchanged. Useful for organization and cable routing.

Input: Audio Output: Same Audio

Signal

Generic signal routing node.

For signal type converters (Audio to CV, CV to Audio, Audio to Data, etc.), see the Converters page.
