Phaser
A Phaser is a somewhat mellower version of the Flanger. Like the Flanger, a Phaser works on the principle of
mixing two identical audio sources together. However, unlike a Flanger, the timing difference between the two
audio sources is very small. The result is that some of the frequencies in the song will be removed or “cancelled
out.” Some people describe this sound as a “wind tunnel” effect.
Enable Button
This button will turn the effect on and off.
Amount Knob and Routing Button
Like the Flanger effect above, the Phaser works best with the Routing button set to Insert mode. This allows
you to completely replace the original audio signal with the phased version (by turning this knob fully clock-
wise) in order to emphasize the effect.
Frequency (Freq)/LFO Knob and Button
The function of the Frequency Tweak knob is determined by the state of the LFO button:
When the LFO button is off, the Phaser will be in Manual mode. The Frequency knob will then control
the phase of the effect.
If the LFO button is on, the Phaser will be in Automatic mode. In this mode, the phase will be adjusted
automatically. The name of the Frequency knob will change to LFO. The LFO knob will then set the rate
of the automatic adjustment—turning the knob clockwise will increase the modulation rate.
Dual-Filter
Audio filters prevent particular frequency ranges within an audio signal from passing through the effect. Torq
features three of the most popular types: Low-Pass, High-Pass, and Band-Pass. The names of these filters de-
scribe what they do. A Low-Pass filter, for example, will only allow low frequencies (bass tones) to pass
through—it will remove the high-frequency (treble) content from the audio signal. A High-Pass filter works
the other way: it allows the treble to pass through while bass is removed. A Band-Pass filter is essentially a
High- and Low-Pass filter put together: it will remove high and low frequencies from the audio signal, only al-
lowing a narrow band of frequencies to pass.
The most important parameter for a filter is its Cutoff Frequency. It determines the frequency where a filter
will begin to stop frequencies. For example, when using a Low-Pass filter with a cutoff frequency of 1kHz, fre-
quencies below 1kHz will pass through the filter unaffected while the frequencies above 1kHz are reduced or
removed. While there are other parameters that also affect the behavior of a filter, Cutoff Frequency is the pa-
rameter that you’ll be controlling in Torq.
Enable button
This button will switch the Dual-Filter on and off.
The effect will still work in Send mode, but it will be less pronounced.
