ToneBoosters Morphit is an AUv3 plugin for headphones correction and simulation and removes any unwanted coloration from your headphones! Enable accurate monitoring and calibration, mix with studio reference equalization, and improve the accuracy of your headphones. Used and trusted by thousands of studios worldwide, and now available on your mobile device! The ToneBoosters Morphit 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, AUM, or others. ToneBoosters Morphit will appear in the list of Audio Unit extensions for effect plug-ins. How to use Morphit as AUv3 plugin for headphones correction: 1. Connect your headphones to your iOS device (using the headphones jack, using BlueTooth, or using an adapter as supplied by Apple). You can use any of the many supported headphones listed here: www.toneboosters.com/tb_morphit_v1.html 2. Start your favourite AUv3 host app (Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others) and add TB Morphit as Audio Unit insert effect to a track or output bus. See below on how to use Audio Units in various host apps. 3. Select the headphones you are using from the list of supported headphones provided within the TB Morphit app. That's it - all audio going through the Audio Unit plugin is optimised for your headphones. Key features: - The same professional sound as the acclaimed desktop version - Hundreds of headphones supported! - Unique feature: allow morphing of the amount of correction from 0 to 200% - Unique feature: allow simulation of any of the supported headphones and see how your mix translates - Unique feature: personalize the headphones target curve - Unique feature: use Harman calibration / target curves - Unique feature: data/measurement visualization mode - No external hardware required; works with any of the supported headphones models - Undo/redo, and A/B comparison - Color themes for the user interface - Max screen support in Garageband - Optimised for iPad and compatible with iPhone and iPod Touch See if your headphones are supported: www.toneboosters.com/tb_morhpit_v1.html What you should know: - Licenses acquired for this platform are not compatible with other platforms. - Audio Unit (AUv3) extensions require an iPad mini 2, iPad 4 or later models.
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.
