RX Final Mix is a real-time plug-in for controlling your peaks and giving your mixes and sub-mixes a smooth sonic balance. The newest member of the RX family of post production tools, RX Final Mix plug-in is built specifically for audio post production professionals and video editors.
The Dynamic EQ feature of the Equalizer module is essentially an EQ with the ballistics of a compressor. You can control Gain, Frequency, Q, and the shape of the up to eight nodes.
Surround sound, program-dependent EQ provides intelligent dynamic control over EQ adjustments. Each node can operate in a dynamic mode, in which the shape and depth of the EQ curve will change and adapt in response to the audio it’s adjusting. This allows an EQ adjustment to behave differently in different scenarios—for example a large explosion, a sudden gunshot, or a dialogue sibilance reduction.
A user-definable threshold sets the point at which the dynamic ballistics begin to kick in. The incoming frequencies located at the EQ node/band is used to trigger the amount of EQ applied. The further it falls above or below the threshold, the greater the adjustment will be. The attack and release times for the trajectory of this dynamic behavior scale in accordance to the type of audio passing through. For example, it will react differently to a sibilant dialogue area as it would a low-frequency LFE burst.
Accentuate sections of the spectrum with the Dynamic EQ – Expand mode. For example, add more impact to effects like explosions with a dynamic low shelf. When the amount of low-end energy hits the defined Threshold, the shelf can boost. But when the amount of energy is below the Threshold, the low shelf isn’t touching the mix.
Three user-definable characters (Clear, Smooth, Thick) allow for more direct control over the adaptive, transparent nature of the limiting algorithm, which is tuned specifically for post production type audio. The True Peak, BS.1770-⅔ compliant limiter provides intelligent digital loudness maximization of the signal, while ensuring there are no True Peak overflows to keep your mixes compliant to delivery specs.
The processor is designed for neutral or transparent limiting. It does so by analyzing the incoming source material and leveraging a psycho-acoustically pleasing algorithm, reacting quickly to transients and reacting more slowly to steady, lower frequency tones. In doing so, it is optimized to preserve transients and present them more clearly in the output signal, even when aggressive limiting is taking place.
Stem and Master Bus Processing
RX Final Mix provides up to 7.1 surround support with control over LFE channel processing, for use on both stems and master busses. If you’re delivering discrete stems, you may wish to use the frequency control and True Peak limiting of RX Final Mix on those stems. However, when using RX Final Mix on your master bus, this post-stem processing will change the relationship between the stems and the master, meaning that the stems sum will no longer equal the mix. As such, we’d recommend not using RX Final Mix on the master bus if you’re delivering stems. If you’re delivering a final stereo or surround mix without stems, RX Final Mix contains specific master bus presets designed to prepare your mix for optimum sound quality, and even specific playback scenarios such as video streaming.
