How We Designed Audacity 4
Why Hacker News recommends it
HN commenters cite it as an insider case study of how a legacy open source app can be redesigned, especially in threads on Audacity releases, FOSS usability and technical debt.

What it is
Tantacrul (Martin Keary), head of design at Muse Group, walks through the multi-year research and design process behind Audacity 4. He covers who Audacity is for, its technical debt, the gradual overhaul of Audacity 3, the new architecture, productivity improvements and rebranding.

There is a lot of good news in open source audio these days. Also see this video presenting the work done and planned for the future version 4 of Audacity: [this video]

I highly recommend this video [1] by the Head of Software at Muse who had a big part in the development of Audacity 4.0. Some great insights and really fun to watch! [1] [this video]

> Free audio editing software that requires hours of learning to be useful for simple tasks. To be fair, the Audacity UX designer made a massive video about the next UX redesign and how he tried to get rid of "modes" and the "Audacity says no" problem: [this video] So this problem should get better in the future. Good UX (doesn't necessarily have to have a flashy UI, but just a good UX) in free software is often lacking or an afterthought.

Audacity had a 5 year plan on removing technical debt and overhauling the UI [this video] (1 hour long video) Will this be merged into Tenacity or are they going further apart?

Well said. It seems to me, many FOSS projects suffer from long time contributors which are extremely conservative and don't like any kind of change. Hence every new or improved feature becomes merely a setting (which barely anybody will discover) which is not enabled by default. The UX does only worsen this way because old cruft coexists with its replacement, settings grow fast, the combinatorial explosion of all feature combinations produces tons of bugs and new users will always be turned off by the first use experience. To make the necessary overhaul, someone with the "power to decide" is needed, which is somewhat incompatible with unpaid open source development. I think this video about

Should watch the pre release video [this video] If what they're saying is true, this project is very much a pile of tech debt. They need to migrate whatever they can early before continuing work on the audio engine.
