Izotope Rx Compression Level

I typically employ parallel compression when working with signals that have clear transients, but quiet, low-level information that seems to get lost among other instruments. If I use compression “normally” as an insert effect, I’ll be able to make the soft hits more noticeable, but end up having to reduce transient peaks to do so.

By duplicating the original signal, heavily compressing the copy, then blending both together, I get to retain the original dynamics, while adding the necessary attitude that makes the whole thing seem more up-front. Since the compressed track is mixed at a lower level, I don’t overwhelm the mix with gain either. In this way, parallel compression allows me to apply extreme compression without any of the typical drawbacks.

2. Not compressing hard enough

Oct 10, 2008 Don't be misled, the declipper in iZotope RX also produces those pops if the settings are too high. Again, RX is a good tool, but you have to make sensible use it for things to work out fine. Again, as I mentioned above, I hear artifacts in the declipped sample posted above (as in some harshness in the music). The amplitude of compression noise is often proportional to the signal level, much like with a 32-bit float sample format. The noise of a 32-bit float format is always 150 dB lower than the signal, while the noise of mp3 or AAC compression is usually only 15–30 dB below the signal level.

In a parallel setup, the compression is much heavier than what you would normally use as an insert effect on a track. If we take the scenario described above, I need to dial in anywhere from 10–20 dB of gain reduction to get the sound I want.

For this in-your-face bite, I’ll start with a fairly conservative ratio (with this high level of gain reduction even low ratios sound dramatic) and pull the attack time toward the faster end of the dial, landing somewhere between 0–5 ms. Since the original signal already contains most of the impact I want, this attack setting tells the compressor to clamp down near-immediately to squash transients, avoiding an overly punchy mix. Additionally, if you’re working with short samples, a long attack won’t grab the signal in time.

Omnisphere is a hybrid synth which is probably best known as a go-to option for soundtrack composers. While there’s still a huge amount of content that will lend itself to cinematic use – dramatic strings, ominous atmospheres and the like – Spectrasonics have broadened the remit substantially for version 2, not only in terms of the styles of sound on offer, but also the synthesis options. May 11, 2018  Of course, it would be a LOT better if Spectrasonics added NKS. What Persing has done instead is set up Omnisphere to work within the limitations of what a specific hardware synth can do (finite numbers of knobs, switches, etc) rather than offering us the ability to use a controller to do practically everything that Omnisphere can do. Sep 14, 2018  Omnishere 2 can link up to the hardware of old synths. You probably already know this. If a person has a hardware moog they can use the moog patches in Omnisphere and all the controls on the hardware work the same only you are playing in Omisphere. No audio outputs. This isn't a feature everyone would use. Omnisphere 2 parameters numbers 1. In terms of sample content, not only does Omnisphere offer about five times the raw sample content in terms of size as the other two, that content has become the stuff of legend. We have long had the iconic burning piano. Version 2 adds to the lore with the musical. Aug 18, 2018  Rate! Even though the parameters don’t show up in the Control+Click list, it IS possible (and even lots of fun) to modulate Omnisphere 2’s AMP and Filter Envelopes with.

Depending on how much of the quieter information you want to be pulled up, a short to medium release will do the trick. You may even want to bump the ratio up higher to bring out some exaggerated pumping and intentional distortion—in the case of parallel compression, this isn’t always a bad thing!

Like a usual compressor, attack and release controls are set to suit the material and will change from project to project. You might want more transient energy from the compressed signal, and in this case, it makes more sense to dial in a longer attack time and shorter release time.

Once you set up parallel processing in your DAW, you will find the process of setting the right parameters quite intuitive, as the compressed copy is simply there to round out the uncompressed version, instead of shine as a standalone element.

3. Not EQing your compressed signal

To get additional control over your processed signal, there’s nothing stopping you from EQing parallel compression returns. If you want really beefy low-end, say in a drum kit, try a boost around 100 Hz to exaggerate the attack of the kick or snare. Placed before the compressor, this will drive it to clamp down harder and alter the overall tone, which can be a desired effect. Cutting or boosting with EQ after the compressor allows you to sculpt the signal further to better fit the mix.

Similarly, if you have a compressor that allows for multiband compression, like Neutron, you can split up your doubled signal into custom frequency ranges and assign different compression settings to each. You might want to bring up the lows, but have the compressor work harder on some mid and high range resonance to prevent disrupting the mix balance when blended in.

Overview

De-ess attenuates or reduces sibilance, the harsh high-frequency sounds that come from “S,” “F,” “X,” “SH,” and a soft “C.” Omnisphere 2 vst zip.

Controls

  • MODES: The De-ess module offers two processing algorithms:
    • CLASSIC MODE: Detects sibilants and attenuates them with a broadband gain envelope. Since attenuation is applied to all frequencies, this mode is less targeted than Spectral De-ess.
    • SPECTRAL MODE: Offers a more transparent, intelligent, and frequency-specific type of de-essing than Classic Mode. Spectral Mode only attenuates the high frequencies where sibilance is most active, leaving the lower frequencies untouched.

How does the Spectral De-ess processing work?

Spectral De-ess is a multiband compressor with dozens of bands. It’s able to compress the level of sibilants, shape their spectra, and avoid modulation of ambient noise. Each band can operate independently or with a link to adjacent bands (adjusted by the Spectral Shaping slider, explained below) and band thresholds can be adjusted for the desired shape of a sibilant (achieved by adjusting the Spectral Tilt slider, explained below)

  • THRESHOLD: Determines the level at which the De-ess module begins compressing sibilance. The Threshold control has two modes that determine how it reacts to incoming signal level. It is specified in decibels, relative to speech level (Relative Mode) or full scale (Absolute Mode).
    • RELATIVE MODE: Determines the level of speech and sets the threshold relatively to that level. This is the default Threshold mode, Relative mode is active when the “Absolute” checkbox below the Threshold slider is not checked.
    • ABSOLUTE MODE: Sets the threshold to a decibel level below full scale (dBFS). This mode is enabled by checking the “Absolute” checkbox below the threshold slider.
  • CUTOFF FREQUENCY: Specifies the crossover point between speech (to be preserved) and sibilance (to be reduced). The Cutoff frequency value functions as the lower boundary for sibilance detection.
  • SPECTRAL FLATTENING: Spectral Flattening determines how much the spectral shape of the sibilant is changed. A setting of 0% leaves the natural shape of the sibilance by applying uniform compression across all bands. A setting of 100% flattens the shape of the sibilant toward a specified noise profile (see Spectral Tilt).

    Understanding Spectral Flattening

    • Think of Spectral Flattening as a way to fine tune the strength of the sibilant processing. The flatter you go, the more the sibilant is reduced.
  • SPECTRAL TILT: Spectral Tilt creates a target noise profile for the sibilance. A setting of 0 creates a natural spectral decay similar to pink noise. Values below or above 0 create a profile that is heavier in low frequencies (like brown noise) or high frequencies (like white noise). Spectral Tilt is most effective when the Spectral Shaping control is set to a non-zero value.

    Understanding Spectral Tilt

    • Spectral Tilt gives you the flexibility to determine what the ideal shape of your high frequency signal could be. Moving the shape toward brown noise moves it toward a darker sound. Moving the shape toward white noise provides a brighter result. Together with flattening and threshold, you can determine how much shaping takes place.
  • SPEED: Sets the attack and release times for the processing. Attack times are program-dependent in both modes.

    • FAST: Uses quicker attack and release times.
    • SLOW: Uses longer attack and release times.

      Are you using the right speed setting?

      • Is De-ess smoothing out the transients too much?
        Settings that are too fast can reduce the high frequency signal too much in the initial transient phase and can introduce a smoothing effect that reduces useful high frequency definition. Try using Slow mode to mitigate this problem.
      • Is De-ess causing pumping in the high frequencies?
        If the settings are too slow, the processor won’t recover quickly enough, resulting in too much high frequency attentuation. Try using Fast mode to mitigate this problem.
