quil VS cpal

We’re pleased to announce Quil version 4.3.1323, the first general release of Quil in four years! You can find the jar at Clojars and the release notes at Github. Thanks to Clojurists Together for sponsoring this work! :)

The quick run speed is great for shortening the feedback loop. I've had great experiences with Lisp-style environments for that reason, and the language is much higher level than Rust while still offering good performance. I've mainly used Quil, the Clojure wrapper around processing: https://github.com/quil/quil

I can't seem to find any clear information on this, only bit and pieces on the repo https://github.com/quil/quil. It doesn't seem to get any updates and Processing 4 and Java 9, seems to brake. SO the project is dead right?

Quil[0] repo has either a homage to _why, or _why has contributed the intro.

Maybe. I thought of using quil for my web enablement needs, but decided that with how few people know Clojurescript, I wouldn't be able to truly share the code in practice.

but if all your trying to do is get something running real quick using quil https://github.com/quil/quil/wiki/Installing

debugging this nightmare bc its blocking my hobby project. by far the most fucked up issue ive encountered since i started rust.

There is a cross-platform audio library for Rust: cpal https://github.com/rustaudio/cpal

cpal crate should work fine for this use case, though it might be unnecessarily low-level for your use case.

I had to do something similar to this a while back. I used cpal.

Working on a live performance software that would let our band have live real-time practices over the internet. Top priority is minimum latency, so I'm trying to hook it up through ASIO. Not much luck yet. I've tried cpal, but I've run into numerous known random bugs (and some versions don't compile for me). At least I confirmed that I can push the audio through a TCP socket successfully.

With https://github.com/RustAudio/cpal you can access the microphone in a cross platform way, but you’ll get values of range [-1,1] out only. To calculate absolute decibels you would need to calibrate for your specific microphone with a known source.

source of example

you need to use a "loopback" device, as shown here - https://github.com/RustAudio/cpal/pull/478 (note, ive only tested this on windows - if its not supported on linux you could always plug your sound card output into its line-in/mic jack)
