FFT Plot

Attention,fuyez cette app pour IPad iOS 9. Bug d'affichage qui alterne le noir et le gris sur un rythme stroboscopique la rendant totalement inutilisable et déclenchant des crises d'épilepsie de mon chat. Marche OK sur l'IPhone. MAJ vite...

Il faudrait juste pouvoir avoir un micro pour écouter son coeur

Très bon outil pour le prix :)

Scale ranges can’t be customized and cannot see low frequencies below 20Hz and DC value. If this were fairly clarified, which it isn’t, I would not have purchased this as it is really useless when those features are what you need.

This app does exactly what it claims to and looks great. I’ll be using it in the classroom soon to demonstrate concepts like “narrow sound frequency band”. Thanks!

I’m a BSEE (University of Washington, 1995) with experience and a bunch of patents in signal processing. This app is an outstanding tool for understanding the spectral content of an audio signal. It was clearly designed by someone with some expertise in the field, and it’s a joy to use.

Works perfectly. My only wish would be to also look at the waveform in the time domain. I use this app for testing new speakers. You will not be disappointed.

I greatly enjoy how feature full and yet simple this app is. It runs great and seems quite accurate. One thing I think is dearly missing is a way to export the signals measured to a file (like csv). Taking pictures is great for qualitative comparison but this tool would be way more valuable if it could be quantitative.

As a studio engineer who has to run live sound a few times a year, this app saves me a lot of trouble. I can ring out mics in a heartbeat and solve problems more quickly on the fly. No more sweeping for the exact frequency to notch, or for where to center the de-esser! It’s especially handy on an iPad with its larger display.

Fantastic! Apps like this are the reason we don’t need to buy a stupidly overpriced bespoke piece of gear for every little niche... unless we want to! Keep up the great work!
