Tube Limiter

The Tube Limiter in Omnisphere is both a limiter and compressor and is an ideal tool for pumping things up in a musical way. It was modeled on the warm sound of the famous Fairchild™ 670 tube limiters of the 1960s with a fixed internal compression ratio and a slower, smoother response than other compressors. It works great as a stereo buss compressor/limiter as well as well for individual instruments.

• LIMIT
  Engages and disengages an additional “brick wall” limiter at the output. The compression controls continue to work regardless of whether the brick wall limiter is engaged or not.

• THRESHOLD
  Sets the audio level at which the unit starts to compress the signal. If the input signal is below the Threshold level, the unit does not apply any compression. Once the level crosses the Threshold, then the compression begins to affect the signal.
  Range: 0 ~ 60 dB

• GAIN
  A make-up gain stage that adjusts the overall output to compensate for compression level reduction.
  Range: 0 ~ 24 dB

• PEAK / RMS
  Allows the choice of PEAK Limiting or RMS compression curves. Peak limiting detects audio transients that are louder than the set Threshold level and applies compression to control those Peaks at whatever level you’ve set. RMS compression detects an audio signal’s average level and applies compression to the overall signal. This helps make the entire audio signal louder. With RMS, there is no specific ceiling for the audio as there is with Peak limiting.

• ATTACK
  Adjusts the amount of time until compression starts once the audio has gone above the Threshold level.
  Range: 0.1ms ~ 400 ms

• RELEASE
  Adjusts the amount of time until compression stops once the audio has gone under the Threshold level.
  Range: 10ms ~ 5000ms
