Nice app!

Wish I could go above 100 hz to test front speakers cutoff. Would be easy feature to add.

Updates after 10 years! Super!

After 10 years this is still updated. It’s a bit specialised but good use case is testing out bass response for audio systems - even home audio. This does that it says and has a nice back to the future feel. Thanks Devs! Keep on updating!

Not working

Found my rattle

Got this to find a rattle in my system. Found it at about 70 Hz. It was the TV base on top of my sound base. This will be an easy fix with some buffer material. Great app.
