Spectral editing in Edison
This demonstrates how to do basic spectral editing in Edison.
Warning: this isn't supposed to sound good nor to be a practical example, and I don't even believe myself that spectral editing is very useful to repair audio, especially not by working on plain rectangles. But I made this to show that it's also doable in Edison.
So, be more creative in the EQ tool, don't do too abrupt cuts, and use it as a creative tool.
