Toneboosters has released Morphit, a headphone correction and simulation plug-in for Mac OS X and Windows.
Here's what they say:
Every headphone has its own, characteristic sound. Did you ever consider how the specific sonic attributes of your cans change your mixing results? Do you ever wonder how your mix would sound on different headphones?
Virtually every existing headphone introduces unwanted changes to the audio. TB Morphit helps to reduce these unwanted effects by improving the response of supported headphones. Moreover, it can simulate the sound of any of the other supported headphones. Hear how your mix translates from one set to another. Monitor how your mix will sound for your audience. This is especially important since several market studies have indicated that the majority of audio content is actually consumed over headphones. For this purpose, Morphit does not only include more than 100 popular studio headphones, but also includes stock ear buds. For faint-hearted headphone enthusiasts, TB Morphit includes free-field and diffuse-field equalization modes and customizable target functions.
Morphit is available in VST, VST3 (Windows) and VST, VST3 and Audio Unit (OSX) plugins. Demo versions can be obtained at: www.toneboosters.com/download
