Hi guys
I am doing some troubleshooting at MCP about CPD and need to listen the recoding I have done. However these recordings are g729 ones. So, MCP has some tool or Genesys or any you may know to listen/convert?
I tried some online tools and didn't work.
Thanks

I know that Genesys PS employees had such a tool some years ago (don't know if they still do, but I assume they do). If you have a contact with them, try asking for it.

have you tried smzip ?

I have used SOX in the past.

Can you please detail? Can't find references to SMZIP being able to play wav files
-
Use Goldwave, it's free and easy to use.

Gold wave doesn't support g729 by default. I need the codec ;)

For what I have researched, the patents for Annex A and Annex B of g729 have expired. There is an open source project called bcg729... I will try to play with it to create a tool for conversion (though this might take some time until I finish).

Hi Cav,
SMZIP utility i think you can use to change codecs.
I don't see option to attach the tool here.
Please let me know how can i send it or attach it?
-
Can you share the download URL? Or send it to cavagnaro.jc@gmail.com ;)
Thanks

No clue on how to use that SMzip :P I tried many ways and ended up damaging the original WAV file...
What I ended up doing was to modify the MCP option cpd.record.fileext to mp3, so now I have nice and small MP3 files with AMD recording.
Cheers!
BTW:
If you could post some sample on how to use the SMzip would be nice :D
-
Hi Cav,
Here are the steps. :
1) Copy the .wav file in as the same folder as smzip.
2) go to CMD and type this:
Type smzip -ac <comma separated codec names> filename.zip <.wav file name >
for eg if filename is 1111.wav then
smzip -ac g729 1111.zip 1111.wav
It will generate the file in the same path.
Please note:
only 8 KHz mono sound is supported.
Hope it helps :) .

I still got an error:

SMzip media preparation utility 7.6.009.09
------------------------------------------
WAVfile(10.wav) incorrect type 0x133 (blk.align=10)
ERROR: could not open 10.wav

Still would like a simple way to do this...will keep testing later as probably some day will need a real G729 encoder
-
Emailed you. Also have decoders for SRTP and AMR-WB/AMR-NB somewhere buried in code for another project.

I was able to use this one as g729 decoder. It has an encoder, but I didnt have the chance to test it yet:
http://www.codecpro.com/LicenseG729.php
it is recomended by freepbx docs for decoding g729 captures:
https://wiki.freepbx.org/display/PC/How+to+decode+and+playback+G.729+audio+streams
(you need Visual C++ Redist 2012 x86 32bits installed)
