Mike Storey and His Plate Reverb (Video)

"Reverberation is the persistence of sound in a particular space after the original sound is produced," says Wikipedia. More often than not, in studio recordings reverb is added digitally; virtually every FOSS or proprietary sound-editing program has a built-in reverb utility. But what if you're the sort of purist who prefers the analog sound of vinyl records to the digital sound of MP3s or CDs? What if you're the kind of musician who records at the original Sun Studio in Memphis to get that original rock and roll sound? That may be overly picky for most musicians, but there are some who would rather sound like Johnny Cash than Flavor Flav, and they're the ones who are going to insist on real analog reverb instead of twiddling a setting in Audacity. There are many types of analog reverbs, of course. One of the purest types, preferred by many audio purists, is the adjustable plate reverb, and Jim Cunnigham's Ecoplate is considered by many to be the best plate reverb ever -- which brings us to Mike Storey, who wanted an Ecoplate-type plate reverb so badly that he spent eight months building one. He'll run your audio files through it for a (highly negotiable) fee, and maybe give you a bit of advice if you want to build your own, although his biggest piece of advice for you (at the end of the video) to think long and hard before you become a home-brew reverberator, with or without advice and components from Jim Cunningham.

      (b) Vinyl doesn't reliably reproduce high frequencies anyways! Typical vinyl recordings had everything above ~15 kHz rolled off. The mastering gear which cut master blanks often couldn't handle higher frequencies, and standard playback equipment couldn't have reproduced those frequencies if they were present anyways.

      Even below the typical mastering process cutoff, vinyl SNR suffers at high frequencies due to the RIAA equalization curve. The reason for the curve is that you can't cut full amplitude HF into a record. It won't play back because needle mass is too high to track large amplitude high frequency grooves properly. The solution applied by the industry was to attenuate high frequencies during mastering, then apply the inverse function in the preamp during playback. The RIAA came up with a standard for this attenuation curve, hence "RIAA equalization curve". (Since analog gear is imperfect at best there was no way to guarantee that mastering and playback gear all had identical curves, so it also introduces a significant source of non-flat frequency response. And as I said, it hurts HF SNR.)

      Not exactly. Audio CDs are fundamentally digital, which means that you are representing a smooth curve with a (non-infinite) series of square blocks. It'll never be perfect no matter what you do. The only sound you can record digitally with perfection is from a digital source... which you will note is typically looked down on in most kinds of music (at least, most music that you would consider listening to on vinyl), and for good reason. Music is almost always fundamentally analog, so recording it using an analog technique makes a lot of sense, from a purist point of view.

      This is wrong in so many ways I don't know where to begin.

      Using the same twisted logic I could make the argument that a vinyl record can only truly reproduce the sounds of musical instruments that use a diamond needle thrust into a piece of plastic. We should only take pictures of people with cameras made out of human flesh.

      Making a "series of square blocks" reproduce a sine wave is easy if the blocks are small enough and you smooth the resulting waveform beyond the limits of the human ear to hear the difference.

I can't say for sure, there can be multiple sufficient reasons. Spatial cues seem sensitive to timing. The better the clock and jitter reduction in a digital system (including initial sampling) the less such cues are perturbed. Other areas that make a real difference are avoiding triggering error correction algorithms and better voltage controllers and power supplies to avoid compressed dynamics. Analog systems have different challenges, isolation from vibration, especially fed back from the speakers, which is destructive of spatial cues, is a big one.

    Plate reverb is synthetic reverb. It is done, literally, by making a large metal plate vibrate. These days it is very rarely done as an actual physical thing since it can be simulated very well digitally, and with more flexibility.

    However, any time you have a new technology, there are always "purists" who claim that it ruins everything and want to do it the old fashion way, hence there are places with real plate reverb units.

    Actual room reverb or ambiance is captured just as function of recording in that space. The micing techniques you use (like what kind of pickup, how close to the musicians and so on) controls the amount. It can also be added later to quite a high degree of realism by taking an impulse of the room and using digital convolution on the audio signal. Still not quite the same as an actual recording in the space for various reasons, but close.

    In terms of studios with famous ambiance, East West has one of the better ones out there. They bought the Cello Studios in California and there are some very good sounding rooms there. On account of that, many acts hire out the space to record in. It is also where they record their own samples, of course.

    As far as getting awesome plate reverb, there'll be some who will say that a pair of well-tuned and maintained mono tube EMT 140 units ganged together as a stereo effect is pretty much unbeatable. But the maintenance and tuning is a real lost art that very few techs remember. Also equally worthy of mention is the EMT 240 gold-foil plate, which has a sound of it own and has arguably been used on so many records that it is a necessary part of a producer's arsenal to get certain vintage sounds.

    Although looked on as black sheeps by many fancy mix engineers, spring reverbs like the ones used back in the day at King Tubby's and Lee Scratch Perry's studios in Jamaica are something that just cannot be emulated with software, and have become such an integral part of the sound of Reggae that some pundits might find it a bit disingenuous to say that Ecoplates are that superior. Just as much, many producers used to splash AKG BX-10 and BX-20 spring reverb on many a track to the point that that sound became an important part of pop music in the late 60's and 70's.

    So I'd venture to say that for anyone reading this who hasn't had experience with the gear mentioned those pronouncements about Ecoplate being so incredible should clearly be taken as a matter of someone's taste, aesthetic and cultural biases, rather than as fact.

    I did not even bother going into the high-end digital reverb category, with serious contenders from Quantec, Bricasti, EMT, Sony, Lexicon, TC Electronics and other brands, many of which have found favor with all of today's price-is-no-object top mix engineers.

    Just the same way a Neumann U-47 microphone can sound pretty bad when not used properly if either of its irreplaceable VF-14m tube inside or its gold-foil capsule have gone to the dogs, this is yet another illustration of what an inexact science audio production really is.

    As always, use your ears!

    Was there a need to list both types of software? Or is there another type of software, that has sound-editing programs that doesn't include this?
    Or was this just another way to toss "FOSS" out there?

    Plate and spring reverb units will produce different output a good ear can hear depending on where the unit is located. I.e a norther high altitude location will have a sound that is different than a sea level equator location. There are issues with gravity waves as well.

  39. There are no good digital plate emulations. by Anonymous Coward · · Score: 0

    There are no good plate reverb emulations yet, so the real thing is the only way to get that sound.

    Modelling a metal plate is way beyond today's available DSP power to do as a real time process. I have run simulations, but they take about 15 hours to process three seconds of audio (at a 22Khz sample rate). The difficulty is that it's very hard to reduce the number of nodes the model uses before it stops sounding like a plate.

    The same problems are inherent in modelling cymbals, which is why no one does that either.

    You can use convolution to emulate a single snapshot of a plate, but it sounds about as realistic as a drum machine cymbal, which is also a single snapshot. One the plate or cymbal is played several times in succession, it's obvious from the lack of model complexity and energy build up that it's a sample.

    Some companies (like UAD) try and get around this by using a combination of a modulated algorithmic 'plate' reverb for the tail, combined with convolution for the initial attack, but it tends to sound just like that, and still doesn't respond like a real plate.

    Just send him a dirac impulse, and create a 'Mike Storey's plate reverb' plugin for audacity. It's not rocket science.
