Hi all, There are vorbis streams available on VLF by Paul Nicholson and Wolf/DL4YHF and a few more known people from the scene. As far as i know these are in vorbis format, like my MF/VLF stream. Wha
Hi Stefan, I don't really know the answer but here's a guess: If I remember right, your MF receiver gets the signal from the antenna through a mechanical filter. The passband is some 8 or 10 kHz wide
Hi Stefan, LF ! For the suitability of "(ogg) vorbis" format as a transport for antenna (or IF) signals please consider reading the articles at english or german Wikipedia about the technical details
Hi Tobias, Stefan and all, Indeed, but despite what Tobias said the Vorbis encoder / decoder leaves extremely weak signal intact, which are *many* dBs below the human hearing threshold. At least with
I tested weak signal detection. Measuring carrier S/N after a range of compression types and quality settings. Test carrier: 400 Hz; Noise: Additive white Gaussian; Bandwidth: 16.666 mHz (60 seconds)
Hello Paul, Thanks, that could be most useful here. Interesting to see the little loss at q=0.5 / q=0.8 but the much lower data rate. I'm also running VBR but q=1 so far, and got 215 kbps. I'm going
