I also truly wish that the next fast lane version of DSDPlus will include the audio decoding of dPMR modes 1, 2 and 3. Many people on the forum have proposed to provide technical documentation and raw audio samples of the control and traffic channels for the developers to work from, me included. So far, security, the United Nations, diplomatic services, local councils, transport and the Red Cross are using dPMR in Europe and around the world.

Do any of you guys know if the great developers of DSDPlus are working on implementing audio decoding of dPMR in an upcoming fast lane release?

They may need raw audio samples and documentation. Often people offer the items and then don't follow through by posting them. If it is a protocol that is not available live to a developer there may not be much need or incentive to go looking for such information.
You could make a raw recording file and then use a service like Zippyshare to upload it to. You could post a link here or try to email the link or files to the email address used for purchasing DSDPlus subscription.

There are some dPMR docs out there, but I don't think they detail the voice data, like how it's interleaved or error corrected. Also, doesn't dPMR support more than just DVSI's AMBE? Has anyone come up with technical details on the other dPMR vocoders?

A lot of info on this 275 pages .pdf
Maybe not enough data regarding voice error correction , but the frame structures are very well explained;
At least channel data decoding (such as RAN, TG s, RID ) could be added to DSD ?
It would be a first step ...

Also in a few days, someone will lend me an Idas dpmr radio, so i can make all the samples required;
Thank you
