Have you tried setting up a FIFO that each program opens and treats as a WAV file?

Audio processing question

by Andy Stewart

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)

Chuck Anderson <cra(a)WPI.EDU> writes: > We have a lot to cover, so we'll be starting right at 7! I really wanted to be there. Last Saturday (5 days ago) I fell and twisted my ankle. It's been sore, but I limped to the coffee shop yesterday, I figured I could limp to the WLUG meeting. But first I had a 4pm routine doctor appointment, I showed him my foot, he said you should get an X-ray. No problem, just to be sure, they can do it in an hour. The X-ray techniciane said: "I'm not a doctor, so I can't tell you anything official, but you should go to the emergency room. I'll send the X-rays there." So the bottom line is I got home about 9:30 with a cast on my broken foot. I think I'll stay here. See you next time. -- Keith
