thanks.
Linmodem is surely a way to go, we also spotted this nice soft-modem that by reading the specs seems very very interesting for it's integration opportunity (connecting pty and audio i/o) and the careful timing consideration https://github.com/randyrossi/fisher-modem .
Did you ever saw / considered this?
Thanks. I didn't know it, but it also seems to only implement slower speeds and not [what I find more interesting] V.34 and/or V.90. Also, the fact that it's already multi-threading seems a bit odd to me. In the end, the modem is nothing but a process that consumes samples and produces characters in the Rx side, and the inverse for the transmit side. Having a kind of library of C functions for this (like linmodem) seems most natural to me. But hey, that's a matter of personal taste.
