Upgrade from 128 to 320 kb/sec

Solved

Hello,
I have a question about audio formats.
I wanted to know if compressed music can be "decompressed," for example, if we can go from a .mp3 format at 128 kb/sec to a .wave format or to a .mp3 format at 320 kb/sec, and whether there would be a loss of quality over repeated compression and decompression?
Or is it like a zip file? The uncompressed content remains the same?
If so, could you recommend a free software to "play" with these formats?
Thank you.

Configuration: Windows 7
Chrome

    Hello

    So, an mp3 file at 128 kbps can be converted ('decompressed') to 320 kbps, however, the quality of the '320' will remain the same as that of the '128'

    The loss of quality already occurred during the initial conversion to 128

    Similarly, converting from '128' to 'wav' can be done, but the quality will remain that of '128'.

    In fact, the initial losses during the encoding of 'wav' to mp3 are permanent

    Here's a free software to 'play' with all these formats:
