AU3FX:Push

AUv3 dynamics processor with noise gate, compressor/expander with external side-chain input, brick-wall look-ahead limiter and hard/soft clipper.

A highly tweakable stereo dynamics processor with noise gate, compressor/expander with external side-chain input, brick-wall look-ahead limiter and hard/soft clipper. AUv3 plugin.

Parameters

Noise Gate

THRESHOLD
When peak level is below this threshold, signal will be silenced.
ATTACK
How fast the noise gate should ramp up to open.
HOLD
How long the noise gate should hold when open.
RELEASE
How fast the noise gate should ramp down to close.

Side-Chain

EXT
When this toggle is active, use the external side-chain input instead of the original signal, if provided by the host.
LOW CUT
Side-chain HPF filter, if S-C FLTR toggle is enabled.
HIGH CUT
Side-chain LPF filter, if S-C FLTR toggle is enabled.
ATTACK
Envelope detector attack time. How fast the dynamic processing should engage.
RELEASE
Envelope detector release time. How fast the dynamic processing should release.
HOLD
Hold time, useful to minimize distortion with fast attack/release time and low frequency input.
LOOKAHEAD
Delays the signal but not the side-chain, so the envelope detector can react to the signal before it comes out. Adds latency to the plugin.
PEAK/RMS
Determines if the envelope detector should look at the peaks or the RMS signal.
LIN/LOG
Sets envelope detector shape to linear or logarithmic.
L/R LINK
When active, left and right channels are linked.
S-C FLTR
When active, the side-chain Low/High Cut filters are enabled.
S-C MON
Switches the output to monitor the side-chain. Useful for tweaking the side-chain filters or checking the external side-chain input.

Compressor / Expander

THRESHOLD
Compressor/expander threshold. At which levels the dynamic processor should engage.
RATIO
The compression ratio. For example, 2:1 compresses the signal so a 2 dB change on input produces a 1 dB change on output. 1:2 expands the signal so a 1 dB change on input produces a 2 dB change on output. 1:1 means no change.
KNEE
The knee radius. Smoothes the threshold point so the processing engages more gradually and less abrubt.
PUMP
When enabled, allows negative ratios. For example, 1:-1 means a 1 dB increase on input produces a 1 dB decrease on output level.
MAKEUP GAIN
Output gain to make up for any gain lost during compression.
AUTO
Automatically add gain calculated from current compression settings.
PARALLEL DRY MIX
Blends between dynamic processing (0%) and dry input signal (100%)

Limiter / Clipper

These settings determines how the output signal after the compressor/expander is processed.

LIM
Applies a brick-wall lookahead limiter, guaranteeing no output above 0 dB. When active, adds latency to the plugin.
CLIP
Applies hard-clipping.
SAT
Applies soft-clipping / saturation.
PASS
Just pass the signal through without any limiting or clipping.
LIM. LOOKAHEAD
Sets the lookahead time for the brick-wall limiter. Plugin latency is the double of this value, plus any Side-Chain Lookahead (see above).

About AU3FX

The AU3FX series is a collection of lightweight and powerful real time AudioUnit effect apps for iPhone, iPad and iPod touch. Ported from the original AUFX Inter-App Audio effects, now in AUv3 format.

Load and use them in an AUv3 capable host, such as AUM.
