That looks like just the encoder, so we would need both the encoder and decoder that takes signed linear. I'll be on the look out for an option too. On Fri, Jan 2, 2015 at 4:54 PM, Thomas Auge <auge@virtues.net> wrote:
G722 can be a native bearer capability on an ISDN b-channel but thats not widely used. MP2 in your case is just establishing a data channel be it via ISDN or IP.
Yup. I'm fairly certain that's what FreeTDM does for G722, else it wouldn't make much sense to have a codec configuration option. :)
Before proceeding I would seek out a license compatible encoder/decoder library that can be used, MP2 can mean so many things their are multiple levels, options and details required to properly implement it. I highly suspect its not an afternoon event, I could be wrong if the right library is found thats license compatible.
There are a couple, T(w/o)oLame comes to mind. (http://www.twolame.org/ LGPL licensed) Any pointers as to which capabilities are needed in such a library? It seems the libraries are as outdated as the codec. :)

There are ISDN devices which establish a digital (data) ISDN connection and then use all kinds of codecs on top of that. Think FreeTDM with G722 - same thing. As far as I know FreeTDM doesn't care which codec you choose for a digital connection. G722 is just the most common use case.
MP2 is still a widely used standard in broadcast, i.e. for remote contributions.
