 Replying to [comment:9 koops]:
 > 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.
