Desktop plugin developer ToneBoosters dipped their toes into iOS with an FX Pack for Audio Evolution Mobile back in 2017. Today they take the plunge with the release of TB Equalizer. This is a dynamic equalizer for AUv3 and IAA! This looks good with serious features like Mid/Side stereo processing, and Artificial Intelligence that offers content related suggestions.

TB Equalizer iTunes Description:

ToneBoosters Equalizer is a top-quality, professional, dynamic equalizer plug-in with an unrivalled workflow and a gorgeous, functional user interface.

The ToneBoosters Equalizer app captures the microphone (or external sound card) input and processes the signals in real time. To use it as a plug-in, use an AUv3-compatible host app such as Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, or others. ToneBoosters Equalizer will appear in the list of Audio Unit extensions for effect plug-ins.

Key features:

- Mastering grade, professional equalizer and spectrum analyser
- The same professional sound as the desktop version
- Up to 16 filter sections with a very wide range of filter types
- Run each section in dynamic or static mode
- Run each section with digital purity or analog character
- Oversampling and anti-aliasing modes to further improve sound quality
- Use Artificial Intelligence (AI) for content-dependent equalisation suggestions
- Audition mode to easily identify problematic frequency areas
- Automatic make up function for every section
- Zero latency mode for live operation
- Lasso function to select and move multiple filters simultaneously
- Piano display to select musical note frequencies
- Output VU meters showing peak and RMS levels simultaneously
- Undo/redo, and A/B comparison
- Color themes for the user interface
- Adjustable colours for every filter section
- Mid, side, left, right processing for stereo input for each section
- Legacy Inter-App Audio (IAA) support
- Efficient, low CPU usage

What you should know:
- Inter-App Audio (IAA) can only use one instance of this app simultaneously. We recommend to use an AUv3 host to use multiple instances.
- Inter-App Audio (IAA) will only work with a single (mono) channel without an external (stereo) input source. The AUv3 version will support up to 16 channels.
- Licenses acquired for this platform (iOS, iPadOS) are not compatible with other platforms.

Jens Guell released JAF Collection, a set of AUv3 recreations of analog filters. JAF, or Just A Filter, arrives with 30+ filters and a Phaser. Unfortunately it also arrives with a UI bug that is being worked on right now. There is also a free JAF Model One app, which lets you explore one of the ten filters in the collection.

Demos are available on the website.

JAF Collection iTunes Description:

The JAF Collection is an exciting set of digital modeled classic analog synthesizer filters (VCFs) for iOS. The emphasis of this collection of audio unit effects is professional analog sounding and optimized behavior with touchscreen usage, features that not many currently available apps and plugins do really offer.

The collection is exclusively available for the mobile iOS (version 11 and higher). The apps and the included audio units are “universal”, so they work on iPhones and iPads the same way and also have basically the same appearance and functionality.

Note: These apps are so-called “audio units” (aka plugins), which usually require hosting audio applications to operate. Although, they come with their own basic host applications, which includes for instance IAA (inter-app-audio) connectivity, like mic input and also have
inbuilt MIDI support, to use the filters out of the box, like external hardware devices, without requiring another host application.

The JAF Collection Filters can also act as a synthesizer module due to the fact, that there is an unison oscillator section (VCOs) built in for testing and for live performances. The analog modeled synthesizer has no advanced control or modulators. It just runs the oscillators continuously and can be controlled by MIDI messages.

A manual is shipped in the IAA enabled distribution app.

YouTuber Noisy Hubbub has a clever name, and an even more clever use for auGEN X in this ambient jam.
