aXGate – Ambisonic Gate/Expander

17.5056.00 excl. VAT

The aXGate is an Ambisonic noise gate and downwards expander. Any processing applied to Higher Order Ambisonics signals has to be handled carefully to ensure that the spatial balance of the sound scene is not disturbed. The aXGate lets you apply a noise gate to your tracks or busses without harming the delicate spatial balance of the Ambisonic signals.

Features and Parameters
The aXGate has the following parameters:

  • Input gain – boost or cut the input gain.
  • Output make-up gain – adjust the output level to compensate for a reduction in overall level due to compression.
  • Threshold – the threshold level above which a signal will have compression applied
  • Ratio – controls the amount of compression applied when signals go above the Threshold
  • Knee width – control how smoothly the compressor goes from uncompressed to compressed as signal level increases. Zero knee width is a hard knee.
  • Attack time – the time in milliseconds for the compressor to become fully active once the signal goes above the Threshold.
  • Release time – the time in milliseconds for the compressor to stop acting on the signal once it falls below the Threshold.
  • RMS or peak detection – control whether it is the signals peak or average levels that are used to determine if the level is above the Threshold.
  • Gain Reduction display – shows the amount of gain reduction applied over time. The range can be adjusted by right clicking and selecting a new range.
  • Ambisonic Order Detection: processing automatically matches the order of the input signal to optimise CPU usage when working with lower orders than the maximum available to the plugin.

Input: Any Ambisonic channel format with the W channel on the first input.
Output: The same as the output.

Plugin Formats:

  • AAX (64 bit) for Windows – Requires Pro Tools Ultimate or Studio.
  • AAX (Apple Silicon/Intel) for Mac – Requires Pro Tools Ultimate or Studio.
  • VST3 (64 bit) for Windows.
  • VST3 (Apple Silicon/Intel) for OSX.

Available Versions: The aXGate is available with 3 levels of spatial resolution, with different maximum Ambisonic orders:

  • a1Gate – gate first-order Ambisonic signals.
  • a3Gate – gate up-to third-order Ambisonic signals.
  • a7Gate – gate up-to seventh-order Ambisonic signals.
Seventh order Ambisonics requires a massive 64 channels for each track! Not all DAWs can handle this so please download the demo version to test if your DAW and workflow is compatible with this product – you might only need the first-order or third-order version!
