MultiDynamics 7 is a powerful multiband dynamics processor useful for mastering, track processing, sound design, and noise reduction. MultiDynamics offers up to 6 bands with independent compression or expansion/gating per band.

Multiband dynamics processing combines equalization and dynamics processing techniques, but is more powerful than a static equalizer or a single-band dynamics processor. Below are some of the possible ways to use MultiDynamics 7:

Frequency-dependent dynamics.
. One simple application of multiband dynamics is to apply compression or expansion to a specific frequency range. For example, you may want to compress the vocals in a mix without affecting the low frequencies (bass, kick drum) or high frequencies (snare drum, cymbals). This is easily achieved by creating a midrange band that covers the vocal range and setting it to compress.

Level-dependent EQ.
You can also think of multiband dynamics as an equalizer that depends on the input sound level. For example, you may want to brighten the sound of a hi-hat, but only when the drums are played softly. This can be achieved by setting a high-frequency band to increase the gain when the input is below the threshold. This is more powerful than using a shelving equalizer that would change the tonal balance equally at all levels.

Noise reduction.
Another powerful feature of MultiDynamics 7 is noise reduction. For this, several gate bands are used whose thresholds are set just above the ambient noise level. MultiDynamics 7 excels at noise reduction and does not suffer from the typical artifacts of FFT-based noise reducers.

Ducking.
You can use MultiDynamics 7 to duck the music behind the narration, so that the foreground dialogue remains intelligible when mixed with the background music. The use of a multiband processor allows you to attenuate the music only in the frequency ranges where there is dialogue energy, which achieves a more transparent effect.

Some of the new features of MultiDynamics 7:
New interface with a dark theme.
It now supports extensive sidechain capability. Each dynamics band can be controlled from the input signal or from an external sidechain input. You can also specify a broadband or filtered band signal, or select the input signal or the external signal filtered by an independent sidechain equalizer. Therefore, you can control a frequency band based on the signal of another frequency band.
The new Learn feature automatically adjusts the band thresholds to the detected peak or RMS levels.
A peak limiter has been added to the output processing.
Input meters and an input gain control have been added.
User-selectable display ranges for dynamic gain and input levels.
New metering section with options for peak, peak and RMS, RMS, and K-system meters.
Real-time spectrum display with many options.
