> How can I calculate the PSNR?
In this case, I don't think you can: You would need a reference file to
able to compare which output is closer to the original.
You could use `tests/tiny_psnr` from your FFmpeg tree to compare the
output files and show that they are nearly identical.
Note that I believe contrary to FFmpeg neither sox nor Audacity contain
native mp2 decoders, both use a third-party library.
