Convert MP3 file to WAV in Mac Mini

Why would you ever want to do that? Not only will it not create a "better" sounding file, as has been pointed out, it may actually sound worse. Essentially the software is having to make an educated guess at filling in all the blanks, as it were. It's kind of like trying to up-rez a low resolution jpeg off the Internet-it can be done but you'll likely be introducing all sorts of distortions. You can certainly go the other direction and convert WAV to MP3 but can't imagine any reason to do what you've asked.

Yes, it is possible to convert like Sfar describes- using "Convert to xxxx ..." but like Jax2 says: why would you?

the mp3 is an audio format which has removed data to make it smaller. converting it to another format WAV or AIFF or AAC or Apple lossless will not recover that data, how could it? the removed data (mp3) is gone gone gone.

best to set the desired format and re-import the music from CD or purchase higher quality online music.

Thanks All, beside wav, what formats is the best in comparision to wav. To my ears, wav is sonicly better than mp3.

besides wav, to save space you might try flac or aac. i'm not really familiar with macs so maybe somebody can chime in regarding the appropriate formats.

houston,

Formats:

WAV and AIFF should sound identical to the orightincal CD. both are 1 to 1 copies of original (if CD). in iTunes, AIFF has the advantage of linking cover art -where WAV will not allow that.
.
"Apple lossless" will be nearly identical to the original but will be about 60-70% file size.
.
AAC is a compressed so data is thrown away. In a system that is very detailed the 320kbps setting soundsvery good. the 128bps sounds OK.
