Vortex Echo ITC is an app that allows you to sweep between 100ms and 600ms and randomly select a live audio/scanner stream from the list of IP streams on your Android phone.

On first use, you may receive an error message. This is because the app needs to access the device's microphone for the audio. The error message will only occur once, and you will not receive any errors after you open the app the next time.

The amount of the slider echo is controlled by the frequency of the audio. A higher frequency results in a greater amount of slider echo being produced.
