(You can reload the EQ-A AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of EQ-A AUv3 plug-in comes as In-App Purchase. The EQ-A based on Classic British EQ from the '70s. With a surprisingly wide range of tonal variations, the EQ-A is an invaluable and professional audio tool with great flexibility and excellent sonic ability. Features: • Standalone and AUv3 plug-in; • Precise port of Rack Extensions plug-in; • Modeled vintage EQ; • Four bands of classic British equalization (the mid frequency EQ sections are «peaking», while the high and low frequency sections are «shelving»); • Each band offers 4 selected frequency centers; • 15 dB of boost/cut per band; • Three high pass filters at 18 dB per octave and three low pass filters at 12 dB per octave; • Stereo (Mono), Mid or Side EQ modes; • Saturation On/Off-button; • The main of the EQ section allows four frequencies at any one time, switchable to one of four frequencies: Low Filter (Shelf): 50, 80, 100, 150 Hz; Low-Mid Filter (Bell): 250, 500, 1k, 2k Hz; High-Mid Filter (Bell): 3k, 5k, 7k, 9k Hz; High Filter (Shelf): 8k, 10k, 12k, 15k Hz; • Undo/Redo; • A/B comparison; • 2x/4x/8x Upsampling; • Macro controllers; • Built-in Gain Match; • Scalable GUI. A series of three high pass filters at 18 dB per octave and three low pass filters at 12 dB per octave are arranged at the ends of the EQ section. They are unique in that the switches can be pushed in simultaneously, offering distinct cut filter combinations with unusual filter curves. The EQ-A extends the features of the original hardware and joins the flexibility of the digital world to the character of the analog processing. Allows you to choose between equalizer modes (Stereo, Mid, Side) and remove analogue saturation from the processing circuit to deliver pure digital sound.

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 EQ's 1. Filterjam also leads on rating (5.0 vs 4.8). EQ's advantage is update cadence (every 2 weeks vs every 22 months) and iOS requirement (10.0 vs 14.0). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. EQ 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 — 22 and 34 respectively. Written reviews complicate that: 90% of EQ'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.
EQ ships an update every 2 weeks, Filterjam every 22 months. Both last shipped on October 1, 2026.
