MODULIZER PRO DSP1224P

Ultra Ambience

Room reverb consists of early reflections followed by the actual reverb. Unlike the VIRTUALIZERPRO

which emulates both components, this effect simulates only the first 15 early reflections. Since our

hearing uses these reflections to determine the room size, they can be used to generate a subtle and

impressive kind of compression of the audio material, without modifying the signal with long reverb tails.

This effect is particularly suited for vocals and also for drum instruments.

The parameters:

VARIATION: Pre-delay: determines the predelay time between original signal and first reflections (0-

200 ms).

EDITA: Size: adjusts the room size.

EDITB: Wall Damp: this parameter controls the damping factor of the walls.

EDITC: Stereo Width: adjusts the stereo width of the early reflections.

EDITD: Reflections: sets the number of early reflections (1-15).

+ Ambience is a very popular effect for vocal sounds, as it provides voices with a warm and rich

sound and brings them to the foreground when mixing.

Voice Canceler

This effect is particularly suited for karaoke or the rehearsal of lead vocals. The Voice Canceler elimi-

nates mono (midrange) vocal tracks from stereo recordings. The low-frequency range, which in most

cases is also recorded in mono, remains unaffected. Backing vocals which tend to be recorded in stereo

will remain unaffected. Signals with a lot of stereo information (e.g. chorus effects etc.) will not be

eliminated completely.

The parameters:

VARIATION: Bass Frequency: this parameter controls the maximum frequency of bass components

to be retained in the mix signal.

EDITA: Gain: adjusts the level of the output signal by +/-6dB.

EDITB: Bass Pan: adjusts the panorama of the low-frequency range.

EDITC: Treble Pan: controls the stereo balance of the mix signal.

Compressor/Limiter

In broadcasting and recording studios signal levels often exceed the headroom of signal-processing

devices and must therefore be reduced in their dynamics to avoid distortion. This is done with compres-

sors or limiters. Although these devices perform similar functions they differ in one essential aspect:

Limiters limit signals abruptly above a certain threshold, while compressors provide a smooth control

process over a wider range. The limiter monitors the signal continuously and reduces its dynamics as

soon as it surpasses the threshold. Any signal level exceeding the threshold is immediately cut back to

a safe value. Compressors, too, monitor the program material and work with a threshold. However, they

dont control the signal abruptly as limiters do, but continuously. Once the signal has exceeded the

threshold it is smoothly reduced in level, independently of the amount of excess level. The compressor

side-chain implemented in the DSP1224P has a soft-knee characteristic.
