How can I convert WMA files to MP3 on a Mac?

I’d suggest Any Video Converter. A pretty great program for the PC, and while I haven’t tried the Mac version I can’t imagine it would be any worse.

Edit: Free version, by the way. I don’t think there’s any reason to get pro.

Edit: ... Not sure why i thought that was video files. Give me a sec, I’m sure I know a converter somewhere for audio.

Last Edit, Really: Okay, I would suggest Audacity, which is a good audio editing program in it’s own right, but you can open a WMA and then save as an .mp3, you just have to make sure to grab the LAME encoder and go through the LAME FAQ for audacity to set up the mp3 codec. Sorry about that mistake. Good luck!

Well, honestly I wouldn’t even bother. Unless, of course, you care nothing about sound quality. WMA, MP3, AAC, OGG, and a number of other formats are what is known as Lossy formats.. essentially the idea behind lossy formats are that they assume that there are certain parts in an audio stream that the human ear cannot detect (e.g., very high and very low frequencies) and so to save on file size, removes these pieces of the audio based on the format’s specific algorithm. When you start with a high bitrate source, like a CD, then convert it into a lossy format it sounds pretty good most of the time. But, then, if you would convert a lossy to another lossy, you would be starting with an already lowered bitrate, which would degrade further as you convert. Not only this, but WMA and MP3 use different ways of determining what can be cut from the file.. converting one from the other will only make your file sound grainy or even garbled.

Another way to look at it would be as if you were to make a photo copy from an original (i.e., your WMA) then make a copy from that copy (i.e., the mp3 you want). It wouldn’t nearly be as nice as if you were to make a fresh copy from the original.

If you have a lot of music, I’m sorry to break the news of this to you, but I would just re-rip it from your collection. Or, optionally, re-download everything with bittorrent as most files that are available are already in mp3.

I’m not one to know much on this topic, but if you really want to go against what @excitatory said, you could just open each WMA file in iTunes and make them into MP3s right there.

And good answer for a new guy, BTW
