DC vs Multiband

DC-9 Overdrive is a circuit modeled overdrive plug-in that emulates the famous Ibanez® TS9 Tube Screamer. The DSP algorithms in DC-9 take into account the entire schematic, using the latest modeling techniques. This gives you an authentic analog sound that matches the character of the physical circuit. DC-9 is an Audio Unit Extension (AUv3) that works inside host apps. Just open up your favorite host that supports Audio Units and add it as an effect. The controls expand when touched so they can be easily seen while tweaking. DC-9 brings the distinctive warm overdrive crunch to your favorite iOS DAW. Compatible with GarageBand, Cubasis, Auria, BeatMaker, AudioBus, AUM, Modstep, and more. DC-9 gets its name from the Diode Clipper circuit used to create the distortion. Accurate modeling of the clipper by circuit simulation gives DC-9 an edge over the common distortion plug- in. The effect was carefully tuned using A/B comparisons to the original stop box. Blamsoft brings their experience creating top notch plug-ins for the desktop to iOS. The same algorithm is found in the popular Rack Extension for Propellerhead Reason. You get a desktop quality algorithm at an iOS friendly price. Tap Developer Website for sound examples. Note: Second screenshot shows the effect of touching a control.

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.
