Hi everyone! I wonder if you have any recommendation for crates or frameworks regarding signal processing in Rust (audio and radio frequency), in particular for complex I/Q streams ? This would include tasks like: resampling filters fourier analysis fast convolution And possibly things that build…

[image] jbe: at least a good FFT library (and maybe a resampling library) might be helpful as a starting point. Try rustfft .

For interfacing RF hardware, I will likely use the soapysdr crate. I have made mixed experiences with SoapySDR in the past (weird behavior when initializing certain hardware, unclear use of certain API calls, etc.), but I don't think there's many alternatives if you want to be somewhat hardware ind…

I think you're looking for this: [image] cpal Low-level cross-platform audio I/O library in pure Rust I've seen this used in my dependencies before, and it makes all the right noises (pun intended) in the readme, but it was just a simple search for audio , so…

I haven't tried it myself yet so I can't attest to its completeness, but FutureSDR is aiming to be a general framework like GNU Radio but in Rust.

[image] simonbuchan: I think you're looking for this: [ cpal ]. Thank you, I will take a look. Writing a short stub, it seems to compile on FreeBSD too. :smiley: [image] kpreid: I haven't tried it myself yet so I can't attest to its completeness, but FutureSDR is aiming to be a general fr…

[image] kpreid: I haven't tried it myself yet so I can't attest to its completeness, but FutureSDR is aiming to be a general framework like GNU Radio but in Rust. I didn't look deeper into FutureSDR yet, but I was able to successfully receive radio transmissions (commercial FM broadcast and …

[image] jbe: Only thing that I'm missing in rustfft is some specialized transforms, e.g. for real-valued signals microfft might work for optimizing on real-valued signals.

I wrote a small benchmark to compare rustfft (0.6.1) and microfft (0.5.0) . [dependencies] rustfft = "6.0.1" microfft = "0.5.0" rand = "0.8.5" num-complex = "0.4.2" use num_complex::Complex32; use rand::{ distributions::{self, Distribution as _}, thread_rng, Rng, }; use std::f32::consts::T…

You should in general use something like criterion - Rust to verify you're seeing a real effect, but that's a big enough gap there's little doubt!
