like many others, you sent me email asking for a copy of the IGP software being mailed to you, or asking for the address of a site to ftp an IGP executable from.
This isn't your fault (it isn't my fault, either), but actually,
I'm the author of a library that implements the audio compression standard GSM 06.10. IGP uses that library. The IGP author released a text via Clarinet (I haven't checked the Dr. Dobb's article) that says that a "software implementation" could be obtained from me; they forgot to say that what I have is the software for GSM, not the software for IGP (which I didn't know about until two days ago.)
I have by now asked Sing Li from microWonders Inc (the company actually responsible for IGP) to provide a binary, who declined, writing

So, if you're not a developer and experimenter---sorry.
You can get the IGP source code via ftp from
site ftp.mv.com in the directory /pub/ddj/1994.internet-special as file igp.zipThat source code also contains a binary version of the GSM library, as file gsm.lib, and a copy of the GSM source code for DOS, as file gsm.zip.
site ftp.mv.com in the directory /pub/ddj/1994.12 as file gsm-105.zip
You can get GSM source code for UNIX from
site ftp.cs.tu-berlin.de in the directory /pub/local/kbs/tubmik/gsm file gsm-1.0.5.tar.Z
The current patchlevel is 5. Use the archie client to find sites closer to you; ftp.cs.tu-berlin.de is difficult to access at times. If you write me an email telling me that you want the GSM source code (not "IGP" or "the speech compression source code" or "the executable"), I will email it to you as a uuencoded, gzip'ed tar-file.
and DEC's ftpmail gateway will tell you how. (I haven't verified this. If all else fails, get back to me and I'll send you the files via email; but please be as specific as you can as to what you want.)
Thank you very much for your patience; I wish you good luck in actually obtaining the program.
