DOLBY S: HELP ME I'm in deep trouble

    Hi everybody,

    we recorded a few months ago some songs with an analog recorder with Dolby S.

    We mixed yesterday but realized later that the dolby switch was turned OFF while we mixed (that explain the hiss) So now we ended up with mixes with hiss and hi end boost.

    Do you think we can fix this properly at the mastering? Is someone know what are the frequencies boosted by the dolby s?

    We had a similar discussion in the Mastering Forum a little while ago about Dolby B.

    Unfortunately, Dolby S is no simple EQ curve; ratehr is is a whole family of level-dependent curves.

    Here's a spec sheet from Dolby on Dolby S.

    Good luck.

    I would say you're screwed. If you like the way the mixes sound besides the noise, you can alway denoise it, assuming you compensated for the other things in the mix.

    yeah we like the mixes apart from the noise because we compensated while mixing. The thing that bug me is the noise and some annoying hi frequencies...

    Is it easy at mastering to reduce the noise/hiss without affecting too much the music?

    Sure, it's pretty easy depending on what they are using. If they are using one of the restoration plugs, make sure you leave the noise at the top or tail of the song so they can fingerprint it.

    do yourself a favor and remix....

    i cannot see a way of compensating for something as heavy as dolby s....

    it's modulating the signal all over the place.... if it were a static boost of a freqency it is no problem compensating..... but compensating for dolby s would require a dolby s circuit!! or maybe a dynamic eq/comp on each channel......

    i'm amzed that you didn't discover it in the process....

    I guess it would be too weird to play the 2 mix through the Dolby S 422 decoder, or even a Dolby SR decoder.

    Sounds like a remix, school of hard knocks, is in order. You'll probably like the mixes better anyway with the Dolby engaged, it should be easier... consider the bad mixes as good practice.

    good luck
