⚠️ This implementation has not yet been fuzzed. Don't use it with untrusted input.

⚠️ The format is likely to change in the coming weeks. Once it is finalized, a detailed specification will be published. Note that files encoded with a current development versions will likely not work (or produce horrible sounds) when decoded in a slightly older or newer version.

⚠️ If you are experimenting with QOA, please be very careful, especially when wearing headphones. You may unexpectedly produce garbage output that can damage your ears. I had more than a few close calls.
