Levels preferences

The level settings can be found in the preferences menu. Here you can adjust the response time and the level range. The preferences menu offers three response modes: impulse (35 ms), fast (125 ms) and slow (1 s).

For an uncalibrated device a level of 0 dB is the full scale maximum. However if you calibrated your device to a defined level of your hardware environment you might observe values above that range if clipping occurs (in that case you should decrease the gain/level of your hardware and calibrate again).

Levels menu

The peaks are indicated by horizontal lines, which inertially adapt to the current level over time (making them easily readable).

Calibration

If you want to properly calibrate your multichannel apps to match with your audio hardware, you have to provide a reference signal of a known level on each channel. You should then set the reference, for example -18 dB, with the reference slider and the app will do all the magic for you if you press the “calibrate” button below. If the level difference between the app and your hardware is much too high the slider range will not suffice. In that case increase the level/gain of your hardware.

MC Levels calibration

You can also adjust the calibration sliders manually, although that is not recommended. If you are using the internal microphone of your device, calibration is not needed and should be reset to default.

Audiobus

All our multichannel Apps (i.e. MC Oscilloscope, MC Levels) are fully Audiobus compatible!

Audiobus is a great way to connect apps and send audio from one to another. You may find it very useful to analyse the audio output of some of your favourite Audiobus compatible apps with the help of our instruments.

All you need to do is start the Audiobus app and select a TwiddleFactor multichannel app as an output and the app that you would like to monitor as input source.

Please find more information about Audiobus here.
