Ahh! The Absolute sound. Funny how many classical-genre records are on that list. Same goes for DVD-A. An alternate explanation to this apart from just being an old audiophile fart, is this keyboard right next to me: the Korg M1. Along with the Yamaha DX7 (*), one of the most popular keyboards in the 80’s, the Korg M1 is actually a PCM based keyboard. I can’t remember the resolution but I doubt it’s 24/96.
are all nearly all digital synthesizers.the sound generation algorithm is based on FM synthesis, but the end result is a PCM bitstream that is sent to D/A converter.
the early gen synths only had 12-14 bits D/A - current generation synths of course have 24 bit D/A.
but modern synths also used sound generation algorithms based on PCM sampling.
Wow, you just surpassed my knowledge of these synths. I owned the DX7 a long time ago but it was a real bitch to create new sounds. It’s much easier with the predefined PCM-samples on the Korg. Do you know the Korg M1 sample rate? I only remember that a friend of mine was impressed by the more than CD resolution.
if it's "better than CD" then probably 48/16a lot of the early wavetable synths were terrible - sampling rates of 32/12 were common - and that's before they compressed the wavetable to fit into limited ROM space
the beauty of FM synthesis was that you didn't have to allocate huge ROM space to store wavetables for your sounds and you can create quite complex sounds using 4 or 8 operators
the downside was it's pretty nonintuitive to create a sound (as you found out) and after a while you start recognising an "FM" sound because every band had a DX7 ... and they were all using factory presets :-)
Lars,
My point to Oscar is that if you critically examine what is available in MC in SACD the much-vaunted software advantage over DVD-A pretty much disappears.
