Re: how to export raw data to Matlab?

Steve, I don't know "Nyquist" other than in "Nyquist frequency", obviously out of context. Gale, thanks for the suggestion. From the specifications it looks like it will work. I have spent some time on how I would streamline the Audacity output. Unfortunately I write it in Word with graphics. I fou...

Re: how to export raw data to Matlab?

Thanks Steve, the file specs were incomplete. What I am looking for is two integer text export files for a stereo recording (one file for each channel) that records a stereo signal as: Filename ch 1.dat [ASCII 44100Hz, Channels: 1, Samples: 34433, Flags: 1] 297 322 341 ..... Filename Ch 2.dat [ASCII...

Re: Connecting Winamp to Audacity

Winamp is in the middle because I want to automatically let it start and stop during the weekend so I do not need to go to the laboratory. I'm sure that can be done by modifying Audacity, but that seemed more work. Yes, we had problems getting very low frequency signals into a sound card. The cheap ...

Connecting Winamp to Audacity

For a scientific school project I am trying to set up the following: I built an experimental low frequency astronomical radio that produces a stereo sound signal. I need to look at these data on a screen so I can check that it works properly and then record the data in WAV format. I am trying to do ...
