Can't make AMR file for iPhone

[tedtv]

Ok, for two days I've googled how to make AMR audio files for my iPhone voicemail and every program that is recommended, for the mac, when downloaded does not have the AMR option for saving. I just downloaded ffmpegX and AMR is listed, but you can not export into the AMR format. This is frustrating for such a simple thing that I want to do. How do I get the ability in ffmpegx to turn my mp3 sound file into an AMR sound file?

Moving you to our ffmpegx section.

Hi
It's easy enough to convert those files to amr with Linux using ffmpeg.
But there's also a program called mobile media converter that will do it.
The program is Mobile Media Converter (v.1.6.1)
From here:-http://www.miksoft.net/mobileMediaConverter.htm

It's easy enough to convert those files to amr with Linux using ffmpeg.

ffmpegX comes with its own copy of ffmpeg, which you could use from the Mac OS X Terminal. You already seem to know it was compiled with AMR capabilities (I couldn't find that, but my test succeeded). Not all pre-compiled ffmpeg binaries from other Mac applications have this option enabled.

The general syntax is

ffmpeg -i input.wav -ar 8000 -ac 1 -ab 12.2k output.amr

-i input.wav specifies the input file. It can be any audio file that ffmpeg can decode.
-ar 8000 specifies the sampling rate of 8000 Hz
-ac 1 specifies the number of channels: "1" for mono.
-ab 12.2k specifies the bitrate of 12.2 kbps
output.amr specifies the output filename. In this syntax, ffmpeg takes the format from the suffix '.amr' .

Substitute ffmpeg and input file and output file with the full path to each file, e.g.:

/Applications/ffmpegX.app/Contents/Resources/ffmpeg -i /Users/tedtv/Desktop/voicemail4.mp3 -ac 1 -ar 8000 -ab 12.2k /Users/tedtv/Desktop/voicemail4.amr

(This example command line assumes your computer user name is 'tedtv' and ffmpegX.app is in /Applications (as it should be). Modify accordingly (in e.g. TextEdit) then copy to the main window in Terminal and hit 'Enter'.)

@Case
My ffmpeg has amr enabled.

ron@ubuntu:~$ ffmpeg

And so has yours.
But maybe the OP has a version of ffmpeg that doesn't have it.

Thanks to all for helping me out. It's all working now. Finally! Yes!
