I was using ARSS to convert audio to spectrograms then back. However, my files https://drive.google.com/open?id=1X24eUOzOGa5uBUHFTtrSmzptIQTz-93l are all echoey. How do I reduce the echo/reverb using ffmpeg or anything command line interface(for python scripting)? Note: I can upload originals if necessary
I have tried altering ARSS setting, mainly the brightness, however, 2.25 is the highest I can push it without introducing static, which would be even harder to remove, on top of the echo.
