Great resource! For those interested in learning the fundamentals of audio programming, I highly recommend starting with Rust. the cpal library in Rust is excellent for developing cross-platform desktop applications. I'm currently maintaining this library: https://github.com/chaosprint/asak https://github.com/chaosprint/asak It's a cross-platform audio recording/playback CLI tool with TUI. The source code is very simple to read. PRs are welcomed and I really hope Linux users can help to test and review new PRs :) When developing Glicol(https://glicol.org https://glicol.org), I documented my experience of "fighting" with real-time audio in the browser in this paper: https://webaudioconf.com/_data/papers/pdf/2021/2021_8.pdf https://webaudioconf.com/_data/papers/pdf/2021/2021_8.pdf Throughout the process, Paul Adenot's work was immensely helpful. I highly recommend his blog: https://blog.paul.cx/post/profiling-firefox-real-time-media-workloads/ https://blog.paul.cx/post/profiling-firefox-real-time-media-... I am currently writing a wasm audio module system, and hope to publish it here soon.

Is it still the case that cpal doesn't support "synchronous" duplex audio where the program inputs audio from a source and outputs it to a sink (either with feedback or outputting unrelated audio), with an integer number of periods (as little as 2) of software-level latency if you copy source buffers to the sink? Last time I used it, each stream is opened in input or output mode and opening both does not run with any guaranteed timing relation.

Is there a good "toolbox" style cli for audio? Like pitch shifting and time stretching etc

I have mixed feelings on cpal: on the one hand, it's been really wonderful to have a library that just works on different platforms. On the other hand, it's an absolute pain in the butt for doing anything simple. I really wish it would have a simple interface for when I'm only worried about floating point data (I ended up creating my own library to wrap cpal's idiosyncrasies for my mixed midi/audio node program: https://github.com/smj-edison/clocked https://github.com/smj-edison/clocked).
