Frekvens is a frequency shifter and delay effect. Unlike a pitch shifter all frequencies are shifted linearly and then fed back into itself using the stereo delay unit. The frequency shifting is achieved with single sideband modulation using a hilbert transform and an infinite impulse response filter for fast computations. Frekvens also comes with a high and low pass filter and a lfo for modulating the delay play head. - frequency shifter - high, low pass filter - stereo delay - core midi cc input - audiobus - inter app audio - audio unit extension - save, load
Multiband Haas Effect
This audio plugin enhances stereo width by applying micro-delays to specific frequency bands. It creates a spacious sound while preserving bass impact and avoiding artificial treble. Adjust crossover frequencies and delay settings for each band to achieve desired stereo expansion.
- Multiband stereo width enhancement
- Adjustable crossover frequencies
- Independent Haas delay per band
- Preserves bass impact
- Avoids artificial treble
- Mono to stereo conversion

Haas effect is a micro-delay applied to either the left or right channel of audio (but not both). This simple effect creates a realistic and natural-sounding increase in the width of the stereo field that still sounds good when mixed back to mono. It is the most simple and effective way to take a mono input and make it sound like stereo. But Haas effect has some problems. First, it can create phase cancellation problems in the bass frequencies, causing them to loose volume. Second, it can sound a bit artificial at high frequencies. This multi-band Haas effect plugin is a simple way to get the stereo width you need in the midrange frequencies without loosing the impact of the bass or making the treble sound phasey. You select any number from one to four bands, each with its own separate Haas delay setting and adjustable crossover frequencies. This makes mono audio sound wide and spacious while preserving the original tone and spectrum transparently.

Verdict
The clearest difference is rating: frekvens at 4.8 against Multiband Haas Effect's 4.0. frekvens also leads on price ($2.99 vs $5.99) and ratings volume (21 vs 5). Multiband Haas Effect's advantage is review sentiment (100% vs 83%) and update cadence (every 3 weeks vs every 2 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
