AutoEQ for speaker and headphone

[pierre]

Hello everyone,

i wrote a software that can equalise your headphone or speakers (anechoic and in-room). The software is open source and will remain so.
I am looking for feedback on what would be useful to you.

What can it do today?

• the software is available as a CLI (a command line tool that geek will like) and an App that most people will prefer
• data acquisition:
  • loading a text file with freq/response and a target file
  • loading data for headphone with a target curve
  • loading data from spinorama.org (if a speaker is in the database, you have access to it from the app)
  • acquire the in-room data from your microphone
• optimise and find an eq that optimise for either being close to a target or improving a score (Olive scores for speakers / Headphone)
• configure the EQ how you want
• Listening
  • you can swap between with / without EQ quickly to see if you like the eq or not; you can also edit the eq dynamically).

What could it do?

• scan your head and compute your HRTF (kind of working)
• extend the in-room part and do it for complex setup (easy)
• show you how a measured speaker will sound in your room (almost working)
• more complicated: tell you where to put your speakers in your room to get good sound
• your idea?

How to use?

• currently only tested on MacOS (Windows, Linux not far on the way)
• you can compile it ... should be easy [autoEQ](https://github.com/pierreaubert/autoeq)
• you can compile the app not that easy [autoEQ App](https://github.com/pierreaubert/autoeq-app) but doable
• why cannot I download an app? it will come soon. I need access to a linux and windows computer to build the other versions and I need a dev account to build on macOS.

How does it looks like today?

Optimisation running

Toons of graphs to understand what's happening, you also see the player with a spectrum analyser
and a mini view of the current EQ. A/B is with the on/off button. The wheel in-between allow to configure
the eq.

FAQ:

• why not a web app: it could be a webapp; it currently is very fast because it is a native app but I may be wrong; i will build a WASM version and see if it is fast enough.
• why build an app like that? there are many already. Yes sure. I wanted to learn Rust and that's the project for it.

I will update when the app are working and easy to test.
Feedback welcome.

UUh - I want to be a beta tester! Would you provide me with an executable?

They are coming. First two are Linux x86 and Mac with an ARM processor.
You can download here: https://github.com/pierreaubert/autoeq/releases/tag/v0.4.44

Windows versions are coming real soon now.

- I did struggle with MacOS security and it took forever to get it to work.
- If someone wants a version for a Intel Mac, let me know.
- For Windows, i am still fighting the system but I am close now both on X86 and ARM.

What to expect: the software can do a few things but it is still in experimental phase. What I really would like to understand is what would be useful to you all.

Hey, so I took an hour or so to test.

For an alpha a really cool state! It probably does not make sense to for what has not been working. Awesome name and logo. No crashes!

So for my use case... I would like to insert a few measurements (woofer, mids, tweeter) and be able to correct them as a "team" and auralize them together. Visual overlays would be great to evaluate X-Over. I am looking forward to the auralization feature! I tried to import im CSVs from REW, but that did not work.

Can you compile for Win 11, too?

for N measurements, that's coming.
for auralizaition not yet.

Can you compile for Win 11, too?

yes but that's painfull and I need to find a better way. I am very close and yet still not there. Should be here next week if I have some time to work on it. I have setup a small lab with a machine for each OS instead of me trying to understand what the hell is happening on GH or in Docker. I am also working on the iPad version.

What framework are you using? Qt?

What framework are you using? Qt?

I wish, that would be easy. I want to learn rust so rust it is. Framework is Tauri (so all rust for the backend with a Typescript frontend). I will get ride of the frontend and also do it in Rust with gpui when it is stable. I put a minimum of logic in the frontend to make it easy.

Sounds legit and future-proof. I have „starred“ and „watch“ the project on GitHub.

I made some progress, they are not visible in the app but
- you can optimise crossovers
- you can play a sweep and the software record each speakers in turn so you have nothing else to do

next steps:
- integrated the upmixer into the player
- wire all the features into the UI
- make a version per platform
