    Audio DSP with AEC 12-in/8-out analog and 2x2 USB Note: when the CPU displays more than a 100 this will turn red, this time the resource cannot be uploaded to the host and needs to be re-edited to reduce processing power. This can be done by deactivating some modules or by choosing a less demanding module.

  • Page 31: Automixer

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB 2.3.8.2 AutoMixer In the AutoMixer tab all input channels are shown with a respective fader control and mute option and routing option. Clicking on ”AutoMixer” button for a certain channel will route the audio through the automixer. Users can select between a gainsharing Automixer or a gating Automixer.
  • Page 32 Audio DSP with AEC 12-in/8-out analog and 2x2 USB Gain(db): Determines the desired target gain for the output of the automixer module. Slope: Sets the aggression of the gain sharing- Low Slope settings cause the module to act just like a conventional mixer. High slope causes the inputs to attenuate more deeply for inactive sources, very much like a gate module.
  • Page 33 Audio DSP with AEC 12-in/8-out analog and 2x2 USB Gating Automixer: A more traditional automixer. A gating automixer uses noise gates to only allow active channels to pass through and prevent inactive channels to contribute to the overall mix. Gain(dB): Determines the desired target gain for the output of the automixer module. Hold(ms): Sets the amount of time a channel remains open after the signal on that channel falls below the Noise Threshold.

  • Page 34: Aec (Acoustic Echo Cancellation)

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB Priority: Adjusts the level of priority for the selected channel. This value feeds into the automixer engine and may influence the automatic gain adjustments decisions. Mute: Mute the selected channel. The Mute function on the channel is after the input to the automixer engines.

  • Page 35: Ans (Automatic Noise Suppression)

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB 2.3.8.4 ANS (Automatic Noise Suppression) The Automatic Noise Suppression can remove noise from the audio when detected. Because of an algorithm that distinguishes human voice from other sounds, such as constant background noise, it can detect the noise and subtract it from the audio signal.

  • Page 40: Expander (Inputs)

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB 2.3.9.2 Expander (Inputs) The Expander module is a helpful dynamic processing tool to increase the dynamic range of an audio signal. An expander engages when the signal drops below a defined threshold. An expander can be seen as a Noise Gate but with more nuanced settings.

  • Page 41: Compressor (Inputs)

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB 2.3.9.3 Compressor (Inputs) A compressor reduces the amount of dynamic range in an audio signal. Dynamic range is the difference between the loudest and the quietest part of a signal. A compressor reduces this range by attenuating the louder parts of the signal and boosting the quieter parts of the signal.

  • Page 42: Agc (Automatic Gain Control) (Inputs)

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB 2.3.9.4 AGC (Automatic Gain Control) (Inputs) Automatic Gain Control maintains the dynamic range while automatically adjusting the audio signal level. The goal of an AGC is to normalize the signal level while maintaining dynamic range.

  • Page 43: Peq (Parametric Equalizer)

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB 2.3.9.5 PEQ (Parametric Equalizer) A Parametric Equalizer is an adjustable filter to attenuate or boost a signal frequency content of an audio signal. The PEQ allows for multiple frequency bands, or filters, with adjustable parameters.

  • Page 44: Afs (Adaptive Feedback Suppression) (Inputs)

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB 2.3.9.6 AFS (Adaptive Feedback Suppression) (Inputs) The Feedback Suppression is a module on each input channel. The module detects fundamentals in the audio signal that causes feedback and adds notch filters to respected parts of the signal that causes feedback.

  • Page 45: Geq (Graphical Equalizer)

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB 2.3.9.7 GEQ (Graphical Equalizer) Like a parametric equalizer, a graphic equalizer is an adjustable filter used to shape the frequency content of a signal. Graphic equalizers, however, are much simpler. Unlike parametric equalizers, graphic equalizers have a fixed frequency and Q (bandwidth).

  • Page 46: Gate (Inputs)

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB 2.3.9.8 Gate (Inputs) The primary purpose of a Noise Gate is to attenuate signals below a set threshold and to allow normal signals to pass when the signal level is above the set threshold. The Gate also controls how quickly the signal is allowed to pass, how long the Gate remains open, and how quickly the Gate opens fully again.

  • Page 47: Ducker (Inputs)

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB 2.3.9.9 Ducker (Inputs) A Ducker is a processing module that reduces the volume of one audio source based on the presence of another. When the volume of the reference audio signal is greater than the specified threshold, the volume of the specified channel will be attenuated.

  • Page 48: Anc (Ambient Noise Compensation) (Inputs)

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB 2.3.9.10 ANC (Ambient Noise Compensation) (Inputs) ANC, or ambient noise compensation, automatically modifies the channel's level to account for background noise in the area. This is accomplished via a complex algorithm that utilizes dedicated “listening” microphone or microphones to pick up background noise and analyse it.

  • Page 49: Filter (Outputs)

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB 2.3.9.10 Filter (Outputs) Each output channel provides a band-pass filter module which consists of a high- pass filter (HPF) also referred to as a “low-cut filter” and a low-pass filter (LPF) also referred to as a “high-cut filter”.

  • Page 50: Delay (Outputs)

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB 2.3.9.11 Delay (Outputs) The delay module applies delay to a selected output channel. Its main purpose is to adjust time alignment. Milliseconds, Meters and Feet: These parameters are interlinked, the display the same delay time measured in three distinct units.

  • Page 51: Output Setting

    Audio DSP with AEC 12-in/8-out analog and 2x2 USB Threshold(db): If a signal pass above the set threshold the Limiter will be engaged.
