Converting Mono MP3 To Simulated Stereo on Linux

If I have a mono MP3 file, is there a way to use ffmpeg or other tool
on Linux to convert it to simulated stereo? (Note, I have Ubuntu.)

Example of simulated stereo:

1. Copy the mono file twice and feed it into L and R channels.

2. By a couple microseconds, delay the playing of the R channel so that
it starts later.

3. Take the L channel and change the reverb ever so slightly.

4. Take an EQ to the L channel as well as the R channel and change it
so that the sound is slightly fuller and exactly the same on the L and
R channels. Then, ever so slightly, change the R channel and alter the
EQ in the lows, mid, and high just a tiny bit, but not too much.


I'm hoping for some kind of way to do this at command line or in a
script.
