Stereo Delay vs BLEASS Multiband Compressor
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Stereo Delay
This audio unit plugin creates natural-sounding stereo delays with unique panning that expands stereo width without sounding repetitive. It features filters and a mixing matrix for dynamic echo placement, ideal for adding depth to music.
- Unique stereo panning matrix
- Natural, moving stereo echo
- Low-cut and hi-cut filters
- Feedback control
- LFO controlled pan
- Requires host app

Blue Mangoo Stereo Delay is designed to be the go-to app a for simple, musically tasteful delay effect. The most unique feature is the way it handles panning of delayed echoes in the stereo field. Most stereo delays set different delay times for the left and right channels, resulting in the famous ping-pong effect. The problem with the ping-pong stereo delay sound is that it's too extreme, and our ears quickly tire of hearing the same pattern of left-then-right delay repeated hundreds of times. This plugin does it differently. Instead of setting delay taps at different times panned hard left or right, it always keeps the same delay time setting for both the left and right channels, but it has a unique mixing matrix controlling the feedback between the left and right channels so that each time the echo repeats, it appears in a new place in the stereo field. This is different from a simple panning delay, because older echoes and newer ones can simultaneously appear at different positions in the stereo field. The result is a very natural stereo echo that expands the stereo width of the sound but doesn't sound repetitive or electronic. It's constantly moving and changing. The wet signal output has low-cut and hi-cut filters. The hi-cut filter tones down the harshness of the delay and makes it sound like natural echoes. The low-cut is especially useful for applying delay without making things sound muddy. At extreme settings the low cut can achieve a lo-fi telephone like delay sound. The signal flow diagram is as follows: Filters => LFO controlled pan => Stereo Delay Lines => Mixing matrix => Feedback to Delay Lines The dry signal (not shown above) bypasses the entire effect. The key difference between this and other delays is the mixing matrix, which is similar to the ones used in feedback delay network reverb effects to mix between multi-channel delays without changing the volume of the sound. It is the matrix (not the LFO) that creates the illusion that the signal has moved to a different location in the stereo field each time it repeats through the delays. *** THIS IS AN AUDIO UNIT ONLY EFFECT. IT REQUIRES A HOST APP SUCH AS AUM, Audiobus, GarageBand, OR Cubasis. IT DOES NOT RUN AS A STANDALONE APP. ***

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
