Comp 609 vs Multiband

Comp 609 AUv3 plug-in — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the Comp 609 AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of Comp 609 AUv3 plug-in comes as In-App Purchase. FEATURES: • 6 Attack, 9 Recovery (Release) and 5 Ratio selections; • External Sidechain and Sidechain signal High-pass filter; • 6 operation modes: M/S, Mid-channel, Side-channel, Mono with Right-channel as Sidechain signal, 2-Mono, linked Stereo (or Mono); • Parallel compression; • 8x Oversampling and 64-bit floating point processing; • Undo/Redo; • A/B comparison; • 2x/4x/8x Upsampling; • Macro controllers; • Built-in Gain Match; • Scalable GUI. COMPRESSOR SECTION: • Threshold determines how much compression will occur. When the input signal exceeds the Threshold level, the compressor engages. A smaller value results in more compression. The available range is from -20 dBu to +12 dBu; • Attack determines how fast limiting will engage when the signal exceeds the limiter Threshold. The available values is from 1 to 6; • Recovery (Release) is the time it takes for the compressor to stop processing after the signal drops below the Threshold value. The available values are 40, 80, 100, 400, 600, 800, 1000, 1500, 2000 ms; • Ratio — this control determines the compressor ratio. The available values are 1.5:1, 2:1, 3:1, 4:1 and 6:1; • Sat. On — this toggle switch enables the Analog Saturation. The saturation has no effect unless this switch is in the «On» (down) position. MASTER SECTION: • SC-Filter — the Sidechain Filter controls the cutoff frequency of a low-cut filter on the compressor control signal Sidechain. The available range is 30 Hz to 240 Hz and Off; • Input Gain controls the signal input level to the plug-in; • The Makeup control increases the signal level out of the compressor to compensate for reduced levels as a result of compression. The available range is -20 dB to +20 dB. The Makeup control does not affect the amount of compression; • Mix — the output balance between the signal processed by the plug-in and the original dry source signal can be adjusted with the Mix control. Mix facilitates parallel compression techniques without having to create additional routings in the DAW; • Comp. In — this toggle switch enables the compressor. The compressor has no effect unless this switch is in the «In» (down) position. • Mode — compressor can operate in six modes: M/S, Mid-channel, Side-channel, Mono with Right-channel as Sidechain signal, 2-Mono, linked Stereo (or Mono). This switch determines the active mode. To use Comp 609 as a plug-in, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — Comp 609 will appear in the list of Audio Unit extensions for effect plug-ins in the host app.

Multiband splits an audio signal into separate channels: one for each of up to four frequency bands. It is useful for doing multiband processing using effects plugins that were not designed for multiband processing. For example, you could do multiband compression using two different compressor plugins, one for bass and a different one for treble frequencies. Or you could process a chorus or flanger effect on the midrange frequencies only, leaving the bass and treble clean. This plugin has two modes of operation: Multi-output and Link Group In Multi-output mode, the app takes a single channel of input and splits it into multiple output channels. Link group mode is a fallback support mode for DAW apps that don't support multi-output audio units. In Link group mode you duplicate the input track several times, once for each frequency band. Then the plugin filters out all but the selected bands on each of your duplicate tracks so that each track contains just one frequency band. It's called "Link Group" because when you duplicate the plugin across two or more tracks you can link the instances together across tracks so that the controls that set the transition frequencies between bands automatically synchronise between all the tracks in the group. HOW IS LINK GROUP MODE DIFFERENT FROM USING HIGHPASS AND LOWPASS FILTERS IN AN ORDINARY EQ TO SEPARATE THE BANDS? Whenever you play two copies of the same track simultaneously you must pay attention to phase alignment. For example, if you copy a track and invert the phase on one copy then the two copies will cancel each other out and you'll get no sound at all. Similarly, if you duplicate a track and process filters separately on each copy, when you combine the two copies back together you will usually get phase interaction at certain frequencies, causing some frequency ranges to be boosted and others attenuated. To avoid this, you would need to use crossover filters that are designed to preserve the phase relationships between each of the bands. The UI of this plugin makes it look like each band is created with a single lowpass and highpass filter pair but that is not the case. In addition to the lowpass and highpass filters we also need several phase compensation filters. Although that could be done with an ordinary EQ plugin it would be quite complicated to configure and test to ensure that no unwanted phase cancellation occurs. WHAT FILTERS DOES THIS APP USE? They are second-order Linkwitz-Riley IIR crossover filters. We use IIR filters to so that when you use many of our plugins in series for real-time performance you don't add audible latency to the signal.
