Hi gang, I think I need something like the Virtual audio cable, but I'd like to know if there are other possibilities. I have two audio programs that I want to talk to each other: gqrx and Dream. gqrx is a software defined radio receiver that can save its audio as a WAV file, or it can stream audio via a UDP port. Dream is a digital radio mondiale (DRM) decoder. Digital radio mondiale is a shortwave radio broadcast in a digital format. Dream can read a WAV file, or it can read audio information from the microphone. It outputs a rather nicely sounding radio broadcast (mono or stereo depending on the broadcaster) with no static and no fading. I have succeeded in recording gqrx audio to a WAV file, and later having Dream decode it. What I want to do is listen to the DRM broadcast in real time. I was unsuccessful in getting Dream to read the WAV file while it was being written. Does anybody have any suggestions as to how this could be done? FYI: reception of DRM broadcasts requires an upper sideband radio receiver that is at least 10kHz wide, a decent antenna, and in my case, a DVB-T dongle and the gqrx software coupled with Dream. Thanks in advance for any help you may provide. Andy -- Andy Stewart (KB1OIQ) Founder: Worcester Linux Users' Group Founder: Chelmsford Linux Meetup Group President: PART of Westford, MA (WB1GOF)
