SpanDSP is a low-level signal processing library that modulates and demodulates signals commonly used in telephony, such as the "noise" generated by a fax modem or DTMF touchpad.
This doesn't add complete support for building for Arm64 with Visual C++, but it does let you include a SpanDSP package built with MinGW in a Visual C++ project.
