GSDSP Quantum Distortion vs BLEASS Multiband Compressor
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
GSDSP Quantum Distortion
Explore four distinct distortion effects—Saturation, BitCrush, Ring Modulation, and Downsampling—blended and controlled via an intuitive XY pad. Shape harmonics, reduce digital resolution, introduce inharmonic motion, and create classic digital degradation for unique audio textures.
- Four distortion algorithms (Saturation, BitCrush, Ring Modulation, Downsampling)
- Intuitive XY pad for blending effects
- Custom waveshaping saturation
- BitWarp for tonal variation
- Tunable oscillator for ring modulation
- Adjustable downsampling rate and jitter
- AUv3 audio effect plugin

Four complementary distortion algorithms — Saturation, BitCrush, Ring Modulation, and Downsampling — blended and shaped through an intuitive XY pad. Saturation Shape harmonics using Quantum Distortion’s custom waveshaping saturation. Adjust Drive to set the intensity from subtle warmth to strong coloration, and use Asymmetry to introduce controlled even-harmonic emphasis of vintage tube characteristics. BitCrush Reduce digital resolution using BitCrush and reshape the crushed signal with BitWarp, which bends the quantization curve for additional tonal variation. This combination allows precise control over both the amount of reduction and the character of the resulting digital artifacts. Ring Modulation Introduce inharmonic motion using ring modulation, generated by multiplying the input with a tunable oscillator. Adjust frequency and amount in real time to create anything from light metallic shading to dense, shifting sidebands. Downsampling Lower the sample rate using Downsampling, reducing temporal resolution for classic digital degradation effects. Set the rate down to 200 Hz or introduce Jitter for controlled randomness, adding instability and movement to the downsampled signal. XY Pad Blending Navigate between the four distortion algorithms using the XY pad, allowing smooth transitions or static blends across the processing modes. The background updates to reflect the current region, providing clear visual feedback while exploring hybrid distortion shapes and interactions. Quantum Distortion is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).

BLEASS Multiband Compressor is the perfect tool for injecting loudness, power and punch into your mixes, stems and tracks. Whether you are creating music on-the-move on your iPad, producing your masterpiece in the studio, or doing both, BLEASS Multiband Compressor dispenses detailed precision control over your music's dynamics. One of the secret weapons of professional mix and mastering engineers, multiband dynamics processors have various advantages over conventional broadband processors. By separating your audio into three frequency bands, and processing each independently, BLEASS Multiband Compressor ensures that loud passages and transients in one frequency range do not impact on how the other bands behave. This eliminates the "volume pumping" effect often exhibited by broadband compressors, making BLEASS Multiband Compressor the perfect tool for processing drum kits, synths, pianos and – of course – full mixes and stems. The plugin works brilliantly with other sources too, from solo instruments to vocals and spoken voice. Unusually for a multiband processor, each of BLEASS Multiband Compressor's three bands features a dual stage dynamics processor. This consists of an Above stage that senses for and processes signals whose level exceeds the Above threshold, and a Below stage that senses for and processes signals that are quieter than the Below threshold. Additionally, each stage can operate as either a compressor or, by dialing in Ratio values below 1:1, an expander. Altogether this makes for phenomenally versatile control over the volume and loudness of your mixes, stems and parts. Another innovative feature of BLEASS Multiband Compressor is its flexible sidechain system. This allows you to choose which bands will key from the input signal in the normal way, and which will key from a filtered and/or external signal. This is ideal for corrective work such as controlling resonances, sibilances and other unwanted artefacts, but is also a fabulous creative tool, allowing for stylish ducking effects and ultra-deep dynamics control. Rounding things off, the plugin provides comprehensive output level and dry / wet balance control, along with a soft clipping feature that ensures overly-hot signals don't become nasty and harsh, but instead take on a classic valve-like saturation character. BLEASS Multiband Compressor stands out for its great sound, innovative features, versatile dynamics control, and exceptional efficiency. More information on https://www.bleass.com/multibandcompressor
