Play and encode audio in reverse?

Question

Using tools available to Trusty Tahr how can I play audio files in reverse (play them backwards)? I would also like to know of tools that will allow me to save or create such reversed audio files...

From GUI with Audacity -

Reversing audio can be done using Audacity Effect > Reverse. After reversing we can choose to just playback or to export in any codec supported.

From CLI with Sox -

On the command line we can reverse audio with sox option reverse:

sox input.wav output.wav reverse ## for conversion
play input.wav output.wav reverse ## for playback

Thank you for this which deals with encoding. For 'reverse playback' of unmodified I have only seen so far playback from within Audacity itself (after the Reverse effect is used) and the `play` utility of sox which will work as: `play input.wav reverse`. Feel free to add these and any others you know of to your answer... There must be more! – andrew.46 Apr 11 '16 at 08:23
