    for Impulse users (sltiverb, acoustic mirror..etc)

    I forgot to post about this after NAMM


    I\'m pretty excited about this, after what Ernest did with GOS impulses.

    great news King.

    I\'m also looking forward to this. I think Ernest\'s work is of high quality.

    Ernest has put a great deal of work into these impulses, and they are of the highest quality.

    These should be definitive products for anyone interested in room simulation. Ernest knows more about this subject than anyone else on the planet.

    This is the \"next generation\" I suppose. I step up from soft reverbs like ren verb?

    If these are better than those that came with the last GOS update, I can\'t wait ......

    hehe, no offense tho, this will probably be the best you can get in the world of impulses... [img]images/icons/smile.gif[/img]
    <font size=\"2\" face=\"Verdana, Arial\">Ah... the voice of reason at last!

    Having said that, I agree that they will probably be the best there is as far as impulses go.

    Hi All

    Thanks for the nice comments much appreciated.

    The sample length of each reverberation impulse (RI) varies - the
    shortest Classical Hall at 44.1khz/16bit is 485kb; the 192khz/24 bit
    impulse is 6 mb. Most of the 176khz/24 bit reverb impulses are typically
    between 8-12 mb. The 44.1khz/16 bit RI\'s fall in the
    600K to 2 mb range.

    Considerable amounts of time, design, testing, energy, skill and capital were
    elemental in the development of this product. Here is a brief outline of the
    process - but please keep in mind that most of these stages include
    proprietary technologies that I have continuously evolved since the mid

    First, the reverb impulses are not \"starter\'s pistol\" samples recorded in a
    hall. This and several other methods have been used to generate
    an acoustic recording of the RI of the space in question.

    In the next step after the recording process, each RI is analyzed with custom
    software designed to reveal the \"key ambient components\" of the hall. Often,
    several RI\'s of the same acoustic space need to be analyzed before the
    \"correct acoustic signature\" is revealed. Intense processing time can be
    required in this phase for just one \"true\" acoustic RI signature. The final
    stage reconstructs the RI in 64 bit floating point architecture with
    conversion into the SDII and Wav 16/24 formats. (Please note that the same
    RI at different sampling rates has to be recompiled from scratch and its
    waveform optimized for the best sound at the given sampling rate.) If you
    listen to the same RI at 44khz, 48khz, 88.2khz, 96khz, 176khz and 192khz,
    all will sound similar but each will have its own unique and subtle sonic

    Processing/rendering was all performed on a 867MHz dual processor Power Mac G4
    using OS X and System 9.22. This machine is about 4 times faster analyzing
    and reconstructing RI than my PowerMac 9600 with a G3 300MHz accelerator
    card. The signal processing for this and all my other sampling CD\'s since
    1993 has been custom proprietary scripts developed using DSP Designer which
    works inside Apple\'s MPW environment . One round of calculations (110 RI\'s)
    took a number of \"round-the-clock\" weeks, at which point all data was
    recalculated again 3 additional times to derive the best possible, most
    accurate sounding RI.

    The production of these Reverberation Impulses are the culmination of years of
    research, and as anyone who is involved in the field of research knows,
    return rarely equals the time invested.
