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...

Would love to have it working on macOS 26 as a plugin for Logic Pro and GarageBand. ### 4/5 — Please bring this to macOS *2025-06-21* One of your best effects. Would love to have it working on macOS as a plugin for Logic Pro and GarageBand. ### 2/5 — Halfway works *2025-05-03* Updated: it stopped working on the iPad as well as the iPhone. Purchased this because it says it is a universal app. It does work on the iPad flawlessly. It does not work on iPhone at all and causes extreme distortion and immediate crashes currently as of April 2025. Probably because of the recent iOS updates. Hope it gets at update! ### 2/5 — Halfway works *2025-04-26* Purchased this because it says it is a universal app. It does work on the iPad flawlessly.

Hope it gets at update! ### 4/5 — Bark Filter loads as an AU into GarageBand on macOS… *2024-10-30* ...but not into Logic Pro as an AU on macOS. It has been a year since my original post describing this problem. Could you please look into this matter? Fails validation and this is confirmed in Logic Pro’s Plug-In Manager. Thank you, Harry. ### 4/5 — Bark Filter loads as an AU into GarageBand on macOS *2023-10-13* ...but not into Logic Pro as an AU on macOS. Could you please look into this? Thanks! ### 3/5 — Great on iPadOS, not working with Logic Pro on macOS *2023-09-04* It’s a great app, but still doesn’t work on macOS in Logic Pro as an AU. Please look into this. Won’t even show up as a plug-in. ### 5/5 — woof! *2023-05-16* el dawgo! 😎 ### 5/5 — Secret sauce *2023-05-10* Use the Triple Band preset on your tracks, thank me later. ### 5/5 — Great for One Shot Mastering *2022-12-25* Got this tip from a forum and it’s working great for me, for my recorded electronic dance music jams at least: select preset „triple band“, enable the limiter on the right side, run the audio with AUM through it - done, it‘s loud and mastered. I‘m lazy and don’t want to spend time on mastering and still get acceptable results - this here gives me exactly that. Let’s hope it will continue to work in the future too. For now: great! ## Frequently asked questions about Bark Filter ### What is Bark Filter used for? Bark Filter is an audio effect processor that functions as a multi-band compressor and analyzer.
