Wow that is huge!

I hope to see a cookbook HowTo on that.

> FIR filters can now be exported in C array format

Which DSPs use those?

I've seen IRS, BIN, TXT / CSV / YAML

WAV of course - is that "the" standard in the XKCD sense?

Are there others?

This is indeed pretty exotic. There’s this project:

DSPiy - Home

Le site du DSPiy, filtre actif numérique à base de DSP. Né sur le forum HCFR, le DSPiy est un filtre actif numérique paramétrable pour faire du filtrage et de la correction d'enceintes audio. 2 canaux en entrée et 6 sorties, avec une qualité audiophile.

www.dspiy.be

And a French user asked me if this format was available, so I implemented it. It wasn’t much work.

Uh oh, DSPiy name collision!

Hello, I just caught an unfortunate bug: the usb library I was using did not link statically into the bundle. It was working on my machines but the compiled bundle was crashing.

The crash is now fixed with v1.3.6 and the library is now statically compiled inside the app bundle.

If you experienced this crash on Mac, please re-download LinFIR from the website: https://linfir.demaudio.com/

The corresponding Windows update will be live in about an hour.

Sorry for the inconvenience.
