ProTools, an industry standard audio edit and mix software, is not accessible for visually impaired. Precisely, it was not accessible and this paper presents how was ProTools access enabled with the help of ProAccess application. ProAccess was created for this purpose and uses mach code injection techniques to load an access enabling bundle into ProTools and applies the method that was published 2 years ago. The paper also describes the relationships in between ProTools, ProAccess, and VoiceOver technology and what results we have obtained together with ProTools, timing of its learning process for a visually impaired person.
