Converter for amr audio files for Mac OS X?

Anyone know of any (preferably free :) ) apps for Mac to convert from AMR format to a friendlier format that Live can understand?

I can playback the amr file using quicktime or realplayer, but can't save/export it to any other format. It's a voice recording made on a Nokia mobile phone.

Thanks in advance for any suggestions!

Once you've converted the AMR make sure to either use external sample-rate conversion (SRC) or at least Live's Hi-Q if the AMR is using low sample-rates (like 8 KHz) unless you like the "special character" of Live's SRC on these.

And watch out pal, some people on this board might frown upon you for using AMR files in Live. :lol: ;)

It's a compression format used by mobile phones for recording audio (like when you use it as a dictaphone).

Cheers folks for the responses.

No, don't have quicktime pro, unfortunately, just the standard free QT.

From the webpage looks like xld can't do it either...

And yes, am ready for the barrage of abuse for daring to use such a low quality recording as input into Live! :wink:

My fallback solution is to try the Nokia Multimedia Suite on my work Dell PC and then transfer it back to my Mac running Live. But am surprised there's no mac-native app to convert directly from AMR to anything!

At least my Installation of the Nokia suite does not offer conversion to WAV (only to other lossy formats). Because of that I am using Miksoft's AMR converter, it's free and it's good.
The Mobile AMR converter is a GUI of the Sony Ericsson AMR converter, so the performance of the conversion is the same as the Sony Ericsson AMR converter.

you can also just play the file in QT and route the audio into live via soundflower. and record it there again.

Thanks folks. I did the soundflower route last night and the sound quality was really fine.

Was more convenient than converting on PC and then dragging it over to Mac.
