SIG 4+

This is the best app I have seen for breaking in new headphones.
I have used it on headphones ranging from $30 to $500 devices and it always makes them sound better.
While the program presents a host of very good options for breaking in headphones I find the Pink Noise generatior to be the best.
And the output graphical levels help ensure I keep the sound at a safe level.
But what really drove me to write this review is the awesome support I received from the developer.
When Catalina was released I experienced some issues due to Catalina's security theater.
I contacted the developer and received an immediate response.
Within an hour of the first email I was back up and running with SIG.
That kind of support I did not expect for a $1.99 USD application.
Other developers should take note and see how customer service is supposed to work.
Thanks again to the developer for both the application and the great support with my issue.

Always looking for tools that aide in commisioning room systems. Use SIG and a few other tools in a semi automated way of getting info in and out of Zoom. Quick on updates and respoonsive developer!

My tinnitus came back. If you suffer from tinnitus you'll know how depressing this is. This app enabled me to find the frequency of my tinnitus and give me some relief while I was working.

I found on YouTube that the closest frequency was 9.8Khz. I entered 9800 into the frequency (click on the frequency number and you can enter this exact number) & reduced the volume to a comfortable level - for me 57%. While the ringing was still there, it was much more comfortable & I could concentrate on my work. I'm hoping over time I can keep reducing the volume and my tinitus fade.

Definately worth the small cost for the app. Thank you for making this simple app available to tinnitus sufferers! 🙏
