Alternative codec similar to Switch or ffmpeg for G729b native decoding for Linux
 

Hi,

I saw a thread similar to this from 10 years ago with no successful outcome, hope something has changed...

I need to decode huge volumes of audios (about 20k audios, 2-8 minutes long) from G729b native codec to PCM Uncompressed wav.

I currently use Switch to do it (https://www.nch.com.au/switch/index.html), it's a drag and drop tool - great functionality but as far as I know it can only be used as a UI. I end up dragging it from Linux env to decode it in Windows and then back to Linux - takes me days to do it.

Ffmpeg doesn't have the option of converting the above codec.

Can anyone recommend a command line tool similar to ffmpeg with the functionality of Switch that I can use in Linux? Or is there a work around with Switch?

Thanks in advance!

I don't know if you got that information from that ten year-old thread, but it's not currently true. FFMPEG has supported G.729b for at least (checks on google) seven years.

Thank you for prompt reply dugan. I overlooked the importance of the following detail, the format is G729.b Sipro Lab Kelvin. I found this thread:

I was hoping there is something a bit more straight forward than that...

Yeah I guess you're out of luck.
