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... Features: • Multi band dynamic range compressor with up to 27 bands • Variable number of compressor bands (1..27) • Threshold/Ratio Attack/Release and Makeup Gain • Linear phase precision filters for maximal transparency • Real time pre/post processing calibrated spectrum analyser • AudioUnit for AUv3 compatible hosts. • Inter-app audio compatible effect. • Audiobus 3 compatible with state saving. • Low latency live usage with mic and headphones. • Audio recorder

WebSDR is an Audio Unit Plugin that plays audio from Software Defined Radio (SDR) streams. It allows you to incorporate the sound of live radio into a live music performance. WHAT IS SOFTWARE DEFINED RADIO? A software defined radio is a device with an antenna that connects to a computer and allows it to receive live radio broadcasts. It features a wide variety of protocols; in addition to standard AM and FM modes found in most consumer radios it typically includes modes for LSB, USB, CW and other settings used to listen in on the CB radios used by taxi drives, marine weather stations, air traffic control towers, amateur radio enthusiasts and many other types of radio broadcasts. The signals you can access using this app are not your own local radio stations; rather they are the radio stations in the vicinity of a collection of free servers, many of them operated by universities. These servers are positioned in many different countries around the world so using this plugin you can listen in on a variety of radio signals in a wide variety of languages and cultures. WHAT DO PEOPLE USE THIS PLUGIN FOR? The crackly sound of an old-style AM broadcast or a conversation between taxi drivers on a CB radio is a musical flavour that can not be replicated with other plugins. If you are looking for some really unique and interesting material to include in your performances or mixes, this plugin will supply. LIMITATIONS This plugin requires Javascript in order to play sound. Unfortunately that means that the UI must be open the entire time you are using it. When the UI is closed Javascript stops running, similar to the way a website stops playing audio when you close a tab in your browser. NOTE: THIS IS AN AUDIO UNIT PLUGIN. IT RUNS INSIDE A HOST APP SUCH AS GarageBand.
