Web Radio Programme Broadcasting Quadraphonic Material

13 Aug

This may be old news to some of you, but there is an interesting radio broadcast on the internet that broadcasts quadraphonic material. The station broadcasts in mp3, so i’m not sure how well it decodes, i’m recording it as i type as a test, but it may be an interesting project for those so equipped

The radio station is here: http://radiomaxmusic.com

The program is broadcast twice on Sundays, at 9am and 9pm USA ET and is called “VINYL RESTING PLACE WITH WILLIE B

He broadcasts mainly in QS, which allows him to use 4-channel tapes he has, just listened to some unreleased quad mixes of ‘Paul Revere and The Raiders”

Hopefully you’ll be able to catch the repeat at 9pm USA ET.

Would be nice to hear of your views etc  🙂

    Last weekend I recorded the entire VRP with Willie B show. The program is presented in mp3 format at 44,100 Hz / 192 kbps. Interestingly they were taking CD-4 demodulated material and encoding that to QS. They also had some SQ encoded material near the end of the show. I put the recorded QS portion through a Sansui QS-1 decoder. Surprisingly there was some separation, acceptable for an internet radio program, but nothing to write home about.

    It’s interesting that there is even a net radio program offering quad encoded material. I do wonder who their intended audience is and how long it will last. I intend to record it again on Sunday and give that another pass through the encoder. It’s a fun experiment.

    O.D.

    Probably nobody knows more about matrix systems than you. Which is why, even though I prefer SQ and QS vinyl sources as my main quadraphonic listening material, you stressed the importance of high resolution digital sources as having superior phase accuracy when being decoded, which I totally agree with.

    Anyway, speaking of potential phase issues, aren’t mp3’s notorious for that? Hopefully this person is using the highest encoded bitrate in their broadcasts, at least.

    But, I shouldn’t complain. It’s good to see somebody trying to do this again. Seeing how relatively rare quadraphonic radio broadcasts by the BBC and American FM stations were in the old days, this is a good thing

      Your correct, mp3 can be the cause of corruption of the encoded matrix information. I’ve not yet managed to check the quality of the broadcasts, but one thing i did find whilst listening to it was the effect of the rear channels appearing beyond the speakers whilst listening to the QS segment and some small degree of ‘something behind me’ whilst listening the the SQ Paul Revere and The Raiders album.

      This could point to the possibility that there isn’t much additional processing by the station and the mp3 encoder is just doing a straight conversion with no additional tweaks possible to reduce bandwidth use.

    So is he live encoding his four track tapes to QS?

    Personally I can’t do anything with this. The only live decoders I have are Dolby Pro Logic, Dolby Pro Logic II, DTS and Dolby Digital. It should be possible to live stream DTS but no-one ever does that I’ve found.

      I suspect he records the shows before hand. I do wonder why the DTS idea hasn’t been used, even at the lowest bitrate available it would be better than mp3.

    Very interesting indeed. Will give a listen to the encore presentation at 9PM to hear what it is all about. Thank you for clueing us in.
