Is this a DVSI licensed and publically available closed source module or something "unofficial" or not generally available to the world at large ? It has obviously long been possible to recode some reverse engineered DSP chip based IMBE implemenation into C++ source code for Wintel/Unix/BSD use, but this would not be free of license and patent issues... and could not be made part of an open sourced project or product without a DVSI deal (and it appears they don't see this as in their interest).Reverse engineering - at least for two common IMBE variants (P25 and MA/COM's ProVoice) - isn't necessary. Both algorithms are published by DVSI through the TIA.
One of WinRadio's more recent offerings includes a software codec option for P25. It's a $99 download - probably DRM'd to your radio's serial number.
