Title: .amr files on Amiga?
Post by: AmigaMance on March 07, 2007, 07:55:38 AM

  Hi.
 Anyone knows if there is a way to play amr files on an Amiga, or to just convert them to another format?

 I'll take this as a "no" :-)

On the PC I use a program from Miksoft to convert AMR to WAV.    IIRC he includes the source code for the process.  I considered trying to compile on Amiga but have not had the time.  Maybe someone else can?

You might give mplayer a shot if you have OS 4 or Morphos. Or is there a 3.x version I do not know of?

@LoadWB
 Let's hope so.

@Colani1200
 There is no OS3.x version but i can run MOS and this format is not supported by the MOS port. I don't know if the OS4 port supports it.

Here are the steps I did to decode the .amr files:

- Download 26104-520.zip (http://www.3gpp.org/ftp/Specs/2003-09/Rel-5/26_series/26104-520.zip)
- Unarchive the two zips.
- Apply quick big endian fix (http://www.iki.fi/sintonen/temp/26104-520.diff) patch
- build it:

Code: [Select]

make -f makefile.gcc decoder
- use decoder the decode the sample:

Code: [Select]

1> decoder t:test.amr t:test.raw
After this stage you have raw sample file, which can be converted to wav, mp3, or whatever you want. For wav you can use for example:

Code: [Select]

1> sox -r 8000 -w -c 1 -s t:test.raw -r 16000 -w -c 1 t:test.wav

@Piru
 Thank you but because i haven't compile a single file in my life, i need to ask 2 additional questions:
 How do i apply the patch?
 Which archive i need to download to be able to compile files on OS3.x?

Hm, perhaps someone with a working m68k gcc setup could grab the src, apply the patch and build the decoder?

(I only have ppc-morphos target in my gcc here)

 In case there are no volunteers, i have a PPC card so a WOS/PUP/MOS exec would be fine. :-)
