I'm the author and maintainer of a number of free, open-source music applications and libraries, of which the most widely-used is probably Sonic Visualiser (website, repo). I'm currently dividing my time between open-source and some proprietary commercial projects.

If you make use of Sonic Visualiser or any of my other free applications, particularly in a commercial context, you might like to consider sponsoring me. I will treat sponsorship income as an incentive (or excuse!) to allocate time to maintenance effort for this work.

• Please do not sponsor me if you are a student or on a low income! Sonic Visualiser is a free application and I would hate for anyone to feel any obligation to pay for it in order to make use of it.

• If you have specific development requirements or would like a commercial support arrangement, consider instead approaching my company Particular Programs Ltd.
