17.5056.00 excl. VAT

The aXCompressor is an Ambisonic dynamic range compressor available in first-, third- and seventh-order variations. The aXCompressor is specifically designed to allow compression of Ambisonic signals without destroying the delicate spatial balance encoded in the B-format tracks.

The aXCompressor has the following features and parameters for controlling the compression of your Ambisonic signals:

  • 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 aXCompressor is available with 3 levels of spatial resolution, with different maximum Ambisonic orders:

  • a1Compressor – compress first-order Ambisonic signals.
  • a3Compressor – compress up-to third-order Ambisonic signals.
  • a7Compressor – compress 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!
