"-i 80088.wav" just gives FFmpeg the input file name. It does not tell FFmpeg anything about what audio format is in the WAV. Later FFmpeg can figure that out for G.729 wrapped in WAV. Older FFmpeg can't, even though it supports decoding ...

Use this command instead in FFmpeg 3.x.x: ffmpeg -i source.g729 dest.wav Now I'll be damned. That works! I still can't quite understand how but it actually works! It's not exactly how I wanted it to work (just load the file into audacity ...

... is clearly a man and woman talking in a non-English language. That sounds like what I hear from the online-converted PCM file. I was simply using ffmpeg from the CLI with a "ffmpeg -f g729 -i source.g729 dest.wav" That is where you are going wrong. That makes FFmpeg think it's a native ...

ffmpeg -encoders | grep -i "g\." That's a bash script. As said I'm on Windows I can run that command in cmd.exe on Windows. It's probably because I have the GNU tools for Windows. but since I always have cygwin ...

Which FFmpeg version is that? Did you get the latest from http://ffmpeg.zeranoe.com/builds/ ? I tried both with this one http://ffmpeg.zeranoe.com/builds/win32/shared/ffmpeg-3.3.1-win32-shared.zip and also this one too http://ffmpeg.zeranoe.com/builds/win64/shared/ffmpeg-3.3.1-win64-shared.zip ...

in fact ffmpeg did open G.729A wrapped in a WAV but the output of its conversion was corrupted. That isn't exactly what you said the first time. You said "unable to load". Wait, I made i unclear with that statement. ...

... rules and don't need higher privileges to do so. So I just downloaded and extracted audacity 2.1.3 from the zip, set it up to English and to use ffmpeg 2.2.2. Tried to open the G.729 but I get the same error. So I guess it's got nothing to do with the portable version. in fact ffmpeg did open ...

how would I unwrap the G.729 out of the WAV? You might be able to do it with FFmpeg at the command-line (-acodec copy) if it can sufficiently understand the file to accept that command, but the problem in any case is that FFmpeg 2.2.2 can't encode G.729. So if ...

As you can see, there's some distortion, but yes I can hear a conversation.
