joerg Posted April 1, 2013 Share Posted April 1, 2013 Hello, Besides the DAQ-interface one of the parameters I have to use will come from a DSP-style routine that runs inside the PC, using data input from sound card. Essentially it is the output of a software demodulator. This software can hand off to the Windows Audio-I/O environment which was originally intended to feed into Winamp. Basically what pretty much all audio applications can read from. Can DAQFactory read in this data? Regards, Joerg Link to comment Share on other sites More sharing options...
AzeoTech Posted April 1, 2013 Share Posted April 1, 2013 Possibly, but only from an external driver. You'd have to use extern() to pull the function in. Link to comment Share on other sites More sharing options...
joerg Posted April 1, 2013 Author Share Posted April 1, 2013 Thanks. I thought extern() was only for constants, not data streams. But anyhow, being a mostly analog hardware guy that would go above my programming abilities and I'd have to use a SW programmer for that. Long term it might be worthwhile to add this link into Windows "WAVE". An example happened at one of my clients. We had to measure mechanical resonances and noises in a production environment. This is typically don't with piezo couplers and then via the sound card. Link to comment Share on other sites More sharing options...
BeeHay Posted May 2, 2013 Share Posted May 2, 2013 I have been thinking of attempting to read-in a "sound wave"... Dropping Geo-phones around a drilling rig location and "listening" to the ground would be cool... Link to comment Share on other sites More sharing options...
AzeoTech Posted May 2, 2013 Share Posted May 2, 2013 You can do this with a streaming LabJack. The sound card actually is surprisingly noisy compared to a real DAQ device like a LabJack. Link to comment Share on other sites More sharing options...
