Bark Filter vs BLEASS Motion EQ

Bark Filter - Critical Band Analyser/Filter/Compressor The multi band filter in Bark takes the approach to match the reception characteristic of the gate where all sounds must pass through: the human ear. The ear behaves as if it contains a bank of filters, each filter passing frequencies within their respective critical band. Two tones apart more than the frequency dependant critical bandwidth are perceived as separate tones. For this reason Bark contains a filter bank with 27 very steep bandpass filters matching the critical bandwidth characteristic of the human ear. In fact, the human ear have also its own built in multi band compression system which are based on the critical bands. Why the name Bark ? The Bark scale is a frequency scale on which equal distances correspond with perceptually equal distances. Above about 500 Hz this scale is more or less equal to a logarithmic frequency axis. Below 500 Hz the Bark scale becomes more and more linear. Multiband compressors can act differently on different frequency bands. The advantage of multiband compression over full-bandwidth compression is that unneeded audible gain changes or "pumping" in other frequency bands is not caused by changing signal levels in a single frequency band. Bark can act both as single band compressor and with up to 27 bands in multiband mode by linking critical bands. The linear phase filter bank with its steep filter slopes can be used for unusually pronounced filter effects too...

The plugin follows a graphic equalizer model, with the position of the three bands’ fader-style cut/boost controls also giving instant visual feedback of the EQ curve. But unlike a conventional graphic equalizer, BLEASS Motion EQ’s band widths are adjustable, making it easy to select the range of frequencies that will be affected by each band. Not only does BLEASS Motion EQ let you balance the tone of your audio, it can also work as a flexible filter too. Low-pass, band-pass and high pass filtering can be achieved by making use of the band mute controls. You can even create an all-pass filter effect by moving the high and low cutoff frequencies close together. The motion part of BLEASS Motion EQ comes in the form of a pair of LFOs (Low Frequency Oscillators). These can control the frequency cutoff point of each band, as well as the amount of cut or boost that each band applies, allowing you to create swirling, ever-shifting tonal patterns. And with the LFOs Synced to your DAW, all manner of rhythmic tonal pulses and movements are possible. The creative possibilities are taken to a new level by BLEASS Motion EQ’s ability to send each band’s signal to its own output bus (with AUM)*. This makes the plugin operate like a crossover, allowing you to route each band to its own track for further processing and mixing. More information on https://www.bleass.com/motion-eq/
