I'm the creator of AudioStretch, and I just discovered this site via Google Alerts. I designed AudioStretch mainly for musicians, for example for transcribing music, and aimed to make it as simple and intuitive as possible. While I never thought of AudioStretch as a tool for empowering blind or low-vision users, intuitive navigation of audio files must be important for that group. So I'm wondering - if you could have an audio playback program created specially for blind or low-vision users, what features & characteristics would you want? Bigger buttons? Voice control? Bookmarks?
