That gives me an idea ... For some time I've been toying with the idea of writing a utility that reads audio in blocks based on UTC timings and saves to a .WAV file . It woudl form part of a long term plan for playing with writing data mode software, using a similar timing protocol to WSJT, ie blocks of data timed on the minute, or 30s or whatever. Using blocks like this makes the software an awful lot simpler to write than trying use real time, continuous streaming audio. I was originally just going to save the audio to a mono .wav, but it would be easy enough to filter, decimate and downconvert to baseband. That way would allow a standalone prog for receiving EbNaut instead of a custom setting in Spectrum Lab The idea of using a .WAV file for storing baseband IQ data has a certain appeal, and one I hadn't thought of, even though stereo I/Q is used in real time for all the Softrock-type SDRs out there..
