Silq Equalizer User Manual



There is two type of screens in SilQ Equalizer. One to 'draw' the EQ curve and 4 screens with faders. A suggested workflow is to use the draw screen to draw the EQ curve for fast results, followed by working out the details on the fader screens.

Both type of screens supports stereoing which means that the left and right channel can be adjusted individually.

The Draw Screen

The draw screen contains the entire audible frequency spectre presenting the EQ curve for both left and right channel in 32 bands.

To change the EQ, simply swipe a finger on the desired frequency area. This way it is possible to 'draw' the EQ curve.

The levels from MIN to MAX is adjustable with three different scales. Click one of the scale buttons to change the scale

NOTE: The EQ curve will auto scale to reflect the range on the current state. This means that if one of the faders/mid frequencies is outside the previous scale, the scaling will change to make room for the 'peaks'.

The Fader Screens

There is 4 screens showing faders to adjust EQ between -20dB and 20dB. Each screen represents frequency bands (bass/lower mid/upper mid/treble). The faders at the top tweaks left channel and those below tweaks right channel. The faders for each frequncy is linked as default. Read further about stereoing below.


SilQ Equalizer can add different EQ to left and right channel. In total there is 64 faders for you to tweak on!

As default the right and left sliders are linked together. To enable stereo eq, press the blue link/unlink button between the left and right slider. Each of these represent the center frequency and slider over and below. You can also use the global link/unlink button for this
In the draw screen you will see that the color of the right channel curve becomes green when left/right is unlinked.

Selecting frequency band

The entire frequency specter is diveded into 4 bands – bass/low mid/upper mid/treble. Use the selectors at the top of the main screen to switch between these bands. These frequency bands are indicated in the draw screen by vertical lines with labels on the tsop.

If you want to mask out and only listen to one of these bands, use the bandpass buttons on the right side. When active, the faders for the selected band is visible and the rest is disabled/not available. Click the same bandbass button again to deactivate bandbass mode.

State/preset saving and recording

The current state of all the frequency sliders will be stored when SilQ Equalizer exits or goes to background mode. When launching, SilQ Equalizer will always start with all frequencies set to '0'.

To save the current settings into your own preset, use the SAVE button on the right side of the screen. Figure out a name for your preset and save.

Record the sound that you hear by tapping RECORD. Press again to stop the recording. A counter inside the RECORD button will tell you the time elapsed and confirm saving when the recording stops.

NOTE that state saving in this context does not mean the same as State Saving in Audiobus which is not supported in SilQ Equalizer.

Bypassing and muting

The output sound is muted as default to avoid feedback when not connected to other apps like Audiobus, AUM or Cubasis. This is indicated by a red color on the MUTE button. Press the MUTE button to switch between muted and un-muted.
Bypass the EQing by pressing BYPASS. Switch back by pressing again. The BYPASS button will change color related to current status. When bypass is active it is not possible to change EQ settings.

Loading user presets and recordings

Press LOAD to open the preset an recordings menu. To listen to a recording, simply press the wanted one and it will start playing. A little icon will show the playing status:

Select factory or user presets by tapping on the wanted one. User presets and recordings can be deleted by sliding from right to left on the desired one:


SilQ Equalizer supports Audiobus as an effect app. Through the Audiobus panel in other apps, you can also start/stop recording within SilQ Equalizer:

Inter-App Audio

When connected to a host app with Inter-App Audio (such as AUM), a transport/switch panel will appear. This contains the icon for the host app to switch back to it. Also, there is controls to start/stop/rewind and record in the host app.

Music Player

To play a song (and do EQing) from your iTunes Library, simply press the media player button. A familiar view will pop up, enables you to pick a song. Playback will start once selected and controls to pause/play and stop will appear under the media player button. The album cover art will appear under the controls

NOTE that copy protected music inside the iTunes Library is not available for SilQ Equalizer and that recording inside SilQ Equalizer is disabled when playing sound from the iTunes Library.
