MacHoe Tip: Convert .amr to .mp3

If you have Samsung D900 or a new mobile phone chances are you record audio to an .amr file which stands for Adaptive Multi Rate.

AMR is an advanced voice codec for GSM, a voice codec translates sound into digital data and vice-versa.

AMR gains efficiency by being “adaptive”. Unlike older standards, AMR automatically operates in different modes depending on signal conditions, and continuously adjusts to match the sounds being transmitted.

AMR is used automatically whenever both the phone and the base station (tower) support it. Nearly all new GSM phones support AMR.

Now to convert .amr to .mp3 you need iTunes and Quicktime, if your on a Mac chances are you already have both app. First you need to open the .amr file with Quicktime and save it as .mp4 if your mobile phone supports .mp4 then you dont need to convert it to MP3, to convert .mp4 to .mp3 open the MP4 file in iTunes, on your iTunes Library right click on the file and select “create an MP3 version”, now you have an mp3 file just locate it by right clicking on the file name and choose “show in finder”.

    Really Useful!
    I had .amr recordings from an old phone. There wasn’t an option to save as .mp4 (Quicktime v10.0 on Mac OS 10.6), but there was an option to save in iphone format .m4v, which I could then ‘add to library’ in itunes and save as .mp3. Perfect way to save recordings of my children singing for prosperity!
    Thanks!

    iTunes, Media Player and Roxio did not (would not) recognize my BlackBerry AMR files. I tried SWITCH. It was easy and it worked perfectly with default settings. It was FREE too! :mrgreen:

    Hello all, I came across SWITCH. That works really well.

    Thanks for this, but I don’t have Quicktime Pro, and it seems I need the PRO version to save as an mp4 file…or am I wrong…

      I see.. didn’t know i was using Quicktime pro, it seems that installing PRO Applications automatically upgrades it to PRO.
