Utilities

SigGen

A signal-generator with sine, pink noise and white noise outputs.

The following controls are provided:

Output selector - set the output signal to sine, pink noise or white noise.

Freq - set the frequency of the sine output from 20 Hz to 20 kHz.

Level - set the signal output level from -inf to 0 dB.

Utility

A multi-function mixing utility.

The following controls are provided:

Phase Selector - invert the phase (polarity) of the left and right channels.

Input Selector - select the input mode (see below).

Trim - adjust the input level from -20 dB to +20 dB.

Pan - set the pan position from 100L to 100R.

Level - set the output level from -inf to 0 dB.

Pan Selector - set the pan mode (see below).

Output Selector - set the output mode (see below).

The signal processing order is as follows:

1. Phase

2. Input

3. Trim

4. Pan

5. Level

6. Output

The input options are:

• Unchanged.

• Swapped left/right.

• The left channel passed to both left/right output channels (right channel ignored).

• The right channel passed to both left right output channels (left channel ignored).

• Both channels summed to a mono mix and passed to both output channels.

• L/R channels converted to mid/side (or mid/side back to L/R).

The pan options are:

• Inactive (pan control is bypassed).

• Constant Power pan-law (-3 dB cut when centre-panned).

• SSL-style pan-law (-4.5 dB cut when centre-panned).

• Linear pan-law (-6 dB cut when centre-panned).

The output options are:

• Use Mid/Side to change a stereo signal to mid/side or an already converted mid/side signal back to stereo.

• Use Hard Clip to prevent excessive output levels by restricting the signal to 0 dB.

The stereo input and output levels are shown by two sets of level meters with input on the left and output on the right.
