Sidechain Compressor Plugin vs BLEASS Spectral Resonator
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Sidechain Compressor Plugin
This audio plugin enables side-chain compression for music production, creating rhythmic pumping effects. It offers true side-chaining in compatible DAWs and a unique sudo side-chain method for broader compatibility.
- Standard compressor features
- Real calibrated VU and reduction meters
- Real-time visual graphing
- True sidechain in AUM
- Sudo sidechain with MASTER/SLAVE
- 3 available busses
- Mono/Stereo modes

This is an AUv3 compatible stereo compressor plugin which is intended for use inside your favourite DAW/HOST such as AUM, Cubasis, Auria, Meteor, AUM or GarageBand etc. So lets start by answering the question what is side chaining? Side chaining is a technique used in a lot of modern dance music which involves using the volume level of one sound source to control another. You can hear plenty of examples of this in modern Trance/Dubstep music where sound engineers use the impact of a bass drum to duck a sustained string sound, creating space in the mix. This can be heard as a rythmic pumping sound which gives your music drive and energy. This compressor is quite unique since it was designed to get around the limitations of AUv3 plugins on iOS and the lack of multi-audio routing inside DAW apps. Until recently it wasn't possible to do true side chaining using AUv3, but now AUM has recently integrated support for multiple inputs and outputs per AUv3 plugin, it opens up a whole new world of possibilities. This is great for AUM users, but this still leaves users of other DAW's in the dark. This is where this app has you covered as it provides a method of sudo side-chaining by allowing you to attach two instances of this plugin to multiple sources and route audio between them to achieve a sudo sidechain. This works by ensuring two instances of the plugin are loaded as insert effects, one being the MASTER and the other a SLAVE. The slave sends audio to the master by means of one of 3 available busses. True side chaining can be achieved in AUM. Simple set the SideChain Mode to 'Normal' and install an instance of the plugin on the channel you want to control. Then using the new 'Multiple Audio Unit Instances' option in AUM you can add a redirection of the controlling source to send to the same bus the plugin is listening to. It's that simple. In this case you need to set both instances to either Bus 2 or 3, since Bus 1 is the original audio. Features: ○ Standard Compressor features. ○ Real calibrated VU and reduction meters ○ Real-time visual graphing of parameters. ○ Real sidechain in AUM. ○ Sudo side chain using MASTER and SLAVE for others. ○ 3 available busses. ○ Mono / Stereo modes. ○ Integrated help.

By converting audio into the spectral domain, BLEASS Spectral Resonator can shift, blur, filter, and restructure the frequency content of any sound before generating resonances. When blended with the source signal, this adds a controllable layer of pitch and timbre. Used fully wet, it produces rich and complex spectral textures. Resonances can be generated from an internal four-voice tone generator or directly from incoming MIDI notes. With up to eight voices of polyphony, glide, pitch bend, and up to 256 harmonics per voice, BLEASS Spectral Resonator can be played from MIDI to create tuned harmonic resonances and evolving spectral textures. Intuitive controls provide detailed manipulation of the resonator behaviour, including unison, detuning, harmonic stretching, density, damping, decay, and harmonic filtering. Harmonics can be restricted to even or odd series, while spectral shifting and blurring further reshape the resulting resonances. A spectral-domain filter lets you select the frequency range used to excite the resonators. The interactive 3D spectrogram visualises resonator activity over time while also providing direct control over the spectral filter. BLEASS Spectral Resonator also includes Freeze and Kill controls for holding or clearing active resonances. Designed to combine deep spectral processing with an accessible interface, it opens new possibilities for harmonic, rhythmic, and dynamic sound design, including inharmonic or atonal material such as drums. BLEASS Spectral Resonator is also available for Desktop. Find more information here: http://www.bleass.com/spectral-resonator
