VirSyn Intros Bark Analyzer, Filter & Compressor For iOS

VirSyn has introduced Bark – a critical band analyzer, filter and compressor for iOS.

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.

Features:

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 frequenc-dependent 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.

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.
