BLEASS Motion EQ vs Spatializer
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
BLEASS Motion EQ
This audio effect plugin offers a graphic equalizer with adjustable band widths for precise tone shaping. It functions as a flexible filter and includes LFOs for dynamic, rhythmic tonal movements. Each band can be routed to its own output for advanced mixing.
- Adjustable graphic equalizer bands
- Low-pass, band-pass, high-pass filtering
- LFOs for dynamic modulation
- DAW sync for rhythmic effects
- Individual band output routing
- Creative tone shaping and filtering

The plugin follows a graphic equalizer model, with the position of the three bands’ fader-style cut/boost controls also giving instant visual feedback of the EQ curve. But unlike a conventional graphic equalizer, BLEASS Motion EQ’s band widths are adjustable, making it easy to select the range of frequencies that will be affected by each band. Not only does BLEASS Motion EQ let you balance the tone of your audio, it can also work as a flexible filter too. Low-pass, band-pass and high pass filtering can be achieved by making use of the band mute controls. You can even create an all-pass filter effect by moving the high and low cutoff frequencies close together. The motion part of BLEASS Motion EQ comes in the form of a pair of LFOs (Low Frequency Oscillators). These can control the frequency cutoff point of each band, as well as the amount of cut or boost that each band applies, allowing you to create swirling, ever-shifting tonal patterns. And with the LFOs Synced to your DAW, all manner of rhythmic tonal pulses and movements are possible. The creative possibilities are taken to a new level by BLEASS Motion EQ’s ability to send each band’s signal to its own output bus (with AUM)*. This makes the plugin operate like a crossover, allowing you to route each band to its own track for further processing and mixing. More information on https://www.bleass.com/motion-eq/
Spatializer
Enhance audio with stereo widening that preserves mono compatibility and avoids phase issues. This tool synthesizes side channel information, ideal for mono sources or adding depth to existing stereo tracks without compromising the mid channel.
- Stereo widening without phase smearing
- Synthesizes side channel information
- Preserves mid channel integrity
- Flexible for mono and stereo sources
- Transparent or strong effect options
- Multiband transient shapers
- Directional RMS distribution visualization

Spatializer is a great choice if you want to widen your sounds but need to avoid: • phase smearing in the mono mix • phasing / comb filter effects (from asymmetric channel delays) • or any changes to the mid channel or mono mix The plugin's main focus is to enhance sounds that have little or no side channel information, where traditional widening approaches like mid-side processing can't be effectively used. It also offers more flexibility in case of mixed inputs, widening narrow components without boosting already existing stereo width to extreme levels that would drown out the mid channel, leading to stereo image problems. Spatializer can also be combined with other effects, for example it's excellent for augmenting large-scale reverbs by enhancing the more immediate space or effectively moving the listener closer to the virtual sound source. At large timescales, the plugin takes on some of the qualities of a reverb itself, while keeping the mid channel sharp and free of any reflections. This could either be used as a special effect in and of itself (depending on the transient characteristics of the input), or be blended together with traditional ambience or acoustic space simulation effects. FEATURES: • Synthesis of side channel information where there was none (stereoization of mono sources) • Linear phase mid channel • Capability to deliver both a neutral / transparent response as well as stronger effects • Built-in multiband transient shapers for delivering a more focused response by suppressing outlier reflections • Multiple visualization options: Directional RMS distribution, position and motion • Effects can range from close-proximity / spatial audio effects to larger acoustic space reflections • Baseline frequency response is optimized to maximize flatness, balancing the spectral density of Left, Right, Side channels The built-in selection of subtly tuned presets and the combined psychoacoustic properties of the above features give more leeway to easily experiment with kinds of source material that have traditionally presented difficulties, like tracks with prominent LF content. Due to its ability to provide transparent, subtle and high-clarity responses, as well as good spectral density characteristics, Spatializer can also be included in master bus effects chains. In multi-track setups it can be used in parallel with other positioning methods to bring more variation to the sound stage or to provide additional ways to adjust the mix.
