Completely re-worked both to make it more compatible with and stable on OS X but also to generally increase flexibility and ease of use. Editing is now much faster and efficient as effects based on filters are now implemented directly on the data rather than on the frequency spectrum of the data as in version 1. This means that in most cases the application of a filter takes no more than a few seconds even for a large file .The editor is also more flexible as you can keep multiple files open for editing, while you record and mix.
