Hi there,
I've been a lurker here for a while. I have no expertise in the contrabass clarinet; I play bass clarinet (rather poorly) but I adore the sound of the contra.

Your post inspired me to experiment with my Logic software.  I posted an mp3 which features three brief sound clips.  The first is a snippet of the original recording of Quincy Jones's "One More Time" from the "Walk Don't Run" soundtrack; it features the contrabass clarinet.  The second is the same clip transposed down an octave with Logic's "harmonic correction" parameter turned on.  The third is also transposed down an octave, but with the harmonic correction turned off.  The whole thing is about 20 seconds long, you can access it here:

I'd love to hear what people think!

There was an LP years ago, but I don't recall if it had any low clarinet tracks...

Which link didn't work for me, somehow...

Subject: [CB] Reproducing Octos

This list is about sharing, and there have been many postings about the possibility of recording the rarest and lowest instruments to "share the sound".  As with the design of the octo-contrabss instruments, the design of a reproduction chain for this sound is at the limits of the state of the art.

Even the perception of extended frequencies is rare.  I have gathered anecdotal evidence and performed informal experiments indicating that bass hearing is developmentally stunted by the bass distortions of speakers.  People who listen predominantly to acoustic instruments (real music) are never fooled by reproduction, whereas the public at large has proclaimed that recordings are indistinguishable from the original event in every medium starting with the Edison phonograph.  Consequently, there is little market for designing accurate speakers since anyone conditioned to music reproduction will not perceive the improvement.

The shortcomings of bass speakers are, first: there is a low frequency cutoff below which the output falls rapidly.  Conventional speakers are designed for a lower limit around G1.  "Subwoofers" designed for Home Theater (computer subs are a mis-nomer) can usually manage a low B.  The only production speaker that extends into octo territory is the ServoDrive Contra, a beast of a subwoofer that costs as much as a second hand contraalto. 

Secondly, anywhere near the cutoff frequency time is radically distorted.  This is exacerbated by normal methods of extending the low frequency of speakers including equalization, passive radiators, vents and worst of all the triple-tuned Bose Wave system.  This means that when reproducing any bass instrument with a sharp attack, the sound of the speaker will overwhelm the rhythm, or the Boombox Effect.

To make matters worse, the recording end of the equation is nearly always modified to reduce the effect of these speaker distortions by simply eliminating the bottom octaves.  Classic microphones, consoles and media all cutoff bass in the same octave as speakers.  Normal production and engineering move the cutoff point still higher (around E2), as documented by Greiner and Eggers in a survey of recordings circa 1989.

So what can be done?  A small goup of engineers are pursuing the bass potential of digital reproduction.  There are new microphone designs from Earthworks (QTC1,) Sennheiser (MKH20) and AKG (C480B/CK62) and headphones from Sennheiser (HD590), Beyerdynamic (DT931) and Ultrasone (most models) that cover octo-contrabass range with precision.  For about $2,000 you can put together a mono reproduction system, and $3,000-$5,000 for stereo including a CD recorder or computer with interface. 

These recordings can be distributed with no loss of bass over the internet and playback systems are a bargain, using a $200-$500 headphone and nearly any headphone amp - except maybe the one that comes in your computer.

I will gladly record any contrabass activity in the Greater New York area, having collected  the above mentioned into travel cases.  The only caveat is that there is substantial low frequency noise anywhere near vehicular traffic, even miles from train tracks and highways in some cases.

p.s. Do not let any recording engineer tell you that his cardioid microphones are better, or even as good as the omnidirectional models listed.  Bass is always stunted by directionality.  Further, no Neumann model has the octo bass response of these either.
