The Passive EQ Collection AUv3 plug-in — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the Passive EQ Collection AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of Passive EQ Collection AUv3 plug-in comes as In-App Purchase. SPECIFICATIONS: • Three classics, EQP-1A, MEQ-5 and HLF-3C, combined in one full-featured equalizer; • Standalone and AUv3 Plug-in; • Modeled vintage Equalizers; • On/Off Analog Saturation; • Undo/Redo; • A/B; • 2x/4x/8x Upsampling; • Macro controllers; • Built-in Gain Match; • Scalable GUI. The EQP-1A based on Classic Program Equalizer from the '60s, original EQ is renowned for its unique ability to boost and cut the same frequencies simultaneously, thereby creating a resonant shelf, the EQP-1A faithfully models the overbuilt transformers and complex tube amplifiers of the original hardware. Conceived and created for broadband equalization, the EQP-1A features 4 low boost/cut frequencies, 3 high-cut frequencies and 7 HF boost points, along with a bandwidth control for shaping the high boost curve. The MEQ-5 based on Classic Mid-Range Equalizer from the '70s, with two bands of midrange boost and one band of midrange dip, the MEQ-5 gets the very best out of the «power region» where guitars and vocals can make or break a mix. The MEQ-5 provides exacting control of the «power region» in program material, that frequency range from about 300 Hz to 5000 Hz in which most of the sound energy is concentrated. The ear is especially sensitive to sounds in this region. In this region, even small resonances in studio acoustics and microphone and speaker responses are very evident in their effect on the listenability of the sound. Three independent sets of controls make it possible to boost on a peak curve at 200…1000 Hz while simultaneously boosting on a peak curve at 1.5…5 kHz, while simultaneously dipping at 200…7000 Hz. The original HLF-3C hardware unit is a true passive design: there are no input/output amplifiers and it does not require any external power. As a result, there is an inherent loss of signal level when using the HLF-3C hardware. The RRS HLF-3C compensates for this inherent signal loss for simplified use in the modern era: it has unity gain upon insertion (there is no insertion loss until one or both of the cut filters is engaged). The broadband EQP-1A, the midrange MEQ-5 and the passive high/low filter HLF-3C together comprise a full range vintage EQ chain. To use Passive EQ Collection as a plug-in, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — Passive EQ Collection will appear in the list of Audio Unit extensions for effect plug-ins in the host app.
Filterjam
This app offers a multiband resonant filter for creating unique audio effects. It divides input signals into four bands, allowing for various sonic manipulations from subtle enhancements to extreme sound mangling.
- Multiband resonant filtering
- 4-band signal division
- Sum or multiply band modes
- Versatile sound shaping
- Ringmod-like effects

Filterjam is a multi-band resonant filter delivering weird ringmod-like filtered sounds. The input signal is divided into 4 bands that are then summed or multiplied together according to the selected mode. Filterjam can be very harsh or gentle, it can add brightness or depth to synth sounds, but it can also completely mangle acoustic sources.

Verdict
The clearest difference is in-app purchases: Filterjam at none against RRS Passive EQ Collection's 1. Filterjam also leads on rating (5.0 vs 4.8). RRS Passive EQ Collection's advantage is update cadence (every 2 months vs every 22 months) and review sentiment (100% vs 83%). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. RRS Passive EQ Collection sells 1 one-off in-app purchase. Filterjam asks for nothing beyond the download.
Filterjam holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 16 and 34 respectively. Written reviews complicate that: 100% of RRS Passive EQ Collection's written reviews are positive against 83% of Filterjam's, so the app with the better star average is not the one people write more warmly about.
RRS Passive EQ Collection ships an update every 2 months, Filterjam every 22 months. The most recent releases landed on October 24, 2026 and October 15, 2026 respectively.
