Hi all,
I'm a big fan of classical music and have recently got interested in quadraphonics, I've built up quite a collection of SQ classical records mostly on the UK EMI label in the ASD 3xxx series as their readily available in the UK.
I've not seen much on QQ about decoding classical ambient recordings so wanted to ask about other peoples experiences with it.
The 2 systems I'm using are the Audition 3.0.1 SQ Final public Script and a home made analogue CBS/Motorola IC gain-riding Logic Decoder.
Comparing the 2 decoding systems I have I'm finding the reverse of what I'm expecting and what I've been reading about on the forums, Thats the Logic decoding is giving a much better concert hall ambiance than the scripts are. I though I must be doing something wrong, I have a couple of SQ Rock/Pop records, DSOTM & AGs Angel Clair so I compared the 2 methods of decoding these, Here as expected the AA script if far and away superior in every way, Its sounds just like the discrete mixes (barring some minor artefacts) and Logic Decoder sounds poor, poor channel separation, poor smeared imaging, noticeable gain pumping - as expected.
So back to the classical, Decodes with the AA scripts just sound wrong, the rear channel ambiance is way to brutal, its sounds unnatural like a delayed reflection of the front channels and in no way sounds like concert hall ambiance. With the 70s logic decoder it just sounds right with no gain pumping or artefacts, in fact I thought the logic was not working so turned it off and the ambiance sounded flatter so the logic is doing its job just emphasising the ambiance where required.
What are other peoples experiences with classical, Could it be EMI have engineered their recordings specifically to work with the CBS logic decoders? They were made in the mid to late 70s after all.
