Hi all,

Does anyone here have experience with decoding Dictaphone recordings stored
in G723.1 foramt? Is there a Windows codec available to decode the files
(i.e. to be able to playback the file without using their player utility?).

You didn't try very hard. :)

try "free 723.1 decoder"

Adore's 'sip softphone' states that there is a Microsoft codec for G723.1.
it appears to be a standard part of MS-Windows.

The Asterix open-source PBX also has a G723.1 codec.

No guarantees that they'll understand Dictaphone files directly, you may
have to do some "file-format" conversion first.

The free G723.1 decoders don't handle the dicatphone wav files correctly.

I had to do some hex editing, but in the end I was able to get a playable
wav file.

I had to deconstruct the wav header manually - strip out the custom wav
header to create a RAW file, run it through a C G723.1 decoder, to finally
get a playable PCM wav file.

Now if I can only find out what is in the header :-)
