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:

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.

I am an audio guy (mixing and writing music for years) and have used both sonarworks reference 4 and IK multimedia Arc system in studio when they are not acoustically treated. I used sonarworks more for headphone mixing on the go with my laptop but I am doing more iPad music production now and this plugin is AWESOME!!!!!! I have all of fabfilter plugins on my iPad but I think I just found a new plugin manufacturer. I just bought the TB Dual VCF filter. If it is as good as it looks, this company is my new go to at a fraction of the cost. How did I miss you all!!! I love how the plugin not only corrects my headphone but will simulate what my mix sounds like in different scenarios which is mandatory to ensure it translates well! Thanks and keep it coming.

This is amazing to have on iOS.

ToneBoosters is offering something that no one else on iOS does. The list of headphones is extensive. And it works well. It would be nice maybe to create user profiles for obscure headphones. My three main cans are supported though!
