Hi all,

I'm in the market for an audio analyser that can do more than my poor FFT from my Siglent scope. Not really skilled yet in the area, but I need the usual things like FFT, THD measurements, etc.

I have gone through the whole thread with interest and intend to build it from Pete's PCB and panels. However, I'm working with a Linux laptop (Ubuntu) so instead of building a desktop PC an cluttering my lab with it, I would rather use an external USB sound card and ideally some Linux software. I don't mind paying for the software, but Virtualbox emulation is a pain and if I can go native I'll be happier.

Anyone has experienced USB sound cards and linux software ?

Regards,
Charles

Arta works OK in wine (direct access to alsa soundcard), I use it in my Headless Amplifier Measurement Workstation . Also Visual Analyzer 32bit Visual Analyser seems to work OK in wine, I will try to use it instead of Arta on my workstation because it offers scope view.

Test & Measurement interface for Soundcard
We recently finished the Interface for Soundcard...I say WE because my nine year old son populated at least 75% of the PCB (with me hovering over his shoulder of course). It's hard to be patient and not grab the iron out of his hands. Anyway, the device works as advertised, was pretty simple to build, and all parts were quite easy to acquire (mostly copy and paste from the BOM to DigiKey and Mouser. I had a hard time debugging it at first as one of the pins on an IC was out of it's socket. This a great tool and I appreciate the hard work Peter put into it...Thank You. I could attach pics (to prove it really happened), but I think you guys already know what it looks like. Thanks Again!!!
