If you want to see what really happened, import both files into Audacity, use a filter to invert one of the files, and slide it around until they are 1:1 (it's off slightly IIRC) and then hit "Play" or downmix to a single track. If both tracks are aligned correctly, you will hear the discarded portions of the original WAV file during the MP3 conversion.
In the two files music starts with a slight delay from one another, and it seems I don't manage to slide them so to eliminate that delay... Any suggestion?
Trial and error - zoom in as far as you can, hit play, realize that it's off slightly, shift using the Time Shift Tool (looks like <----> in the toolbar) very very slightly, repeat. It takes some time, but I've done this comparing FFmpeg's encoding using the libfdk_aac encoder vs the aac encoder.
Now I managed to synchronize them... but all happens is that they play together now... Where's the comparison...? On the first of the two, I applied the `invert' effect. Rodolfo
