Did you ever want to listen to your favorite songs from the past three years? How about having your top five artists in one playlist? Kaign’s filters are here to make that and more happen, in the most convenient way: 1st filter - All songs with at least 4 stars released after 2014 2nd filter - All songs from a list of artists names. Kaign features a visual filters editor which lets you create the above filters quickly and intuitively. Once applied to your library, Kaign filters returns a playlist of songs matching your criteria. You could start listening to the playlist right away or save it as a dynamic playlist, which will get updated as you add and/or remove songs from your library that match its criteria. Because Kaign filters are not linked to any music provider, they are completely portable and sharable. You can share any filter you’ve created with your entourage via email or AirDrop. Once received on any apple device (iPad, iPhone, Mac) which has Kaign installed, the filter will automatically open and is ready to be saved and used. The usability of Kaign filters is almost unlimited. You can combine more than one filter both inclusively or exclusively on any Music library (Apple and Spotify currently supported) as Kaign relies on meta tags to apply filters. These meta tags could be in any language available in Unicode. Simply, you can filter by genres, titles and artists’ names in English, Korean, Japanese, Punjab, Russian, Persian, Romanian, Afrikaans, Arabic, Latin, German, Italian, Spanish, French, Tasmanian, Mandarin, Polish, Bulgarian, Croatian, Serbian, Dutch, etc. We are working hard to translate the Kaign interface in as many languages as we can.

Dub Filter is a filter plugin modeled after King Tubby’s iconic Big Knob, a passive high-pass filter with eleven frequency steps from 70Hz to 7.5KHz. This filter defined the sound of the entire "roots" era of Jamaican music. On top of the main stepped Frequency knob and the Impedance (resonance), the filter also offers control over its behavior including Magnetism, Character, Dynamics, and Artefacts controls. We have also included two modulation sources, LFO and Envelope Follower, to enhance the creative possibilities of the plugin, from rhythmic pulsations to organic filter movements. Available as Standalone and AUv3.

Verdict
The clearest difference is price: Kaign at Free against Dub Filter's $14.99. Kaign also leads on update cadence (every 2 months vs every 15 months). Dub Filter's advantage is in-app purchases (none vs 7) and ratings volume (6 vs 1). On rating, review sentiment, ads and device support there is nothing between them.
