Bass processor

[Matttcattt]

I remember reading in a thread about a bass processor (correct term?) that replicated the bass (i think it was 20-40Hz) into the sub frequency range (i think it was 10-20Hz).

Does something like this exist, or did i dream it?

Thanks,

Matthew

Commonly known in muso circles as an "Octaver" much favoured
by guitarists who don't like bass players and frustrated guitarists
playing bass incapable of resisting "widdling" up the neck.

(can you guess I play bass and can't play guitar ?)

Basically requires a single note input in the basic versions,
the more advanced versions support polyphony , i.e. chords.

As far as I know an accurate half octave generator does not
exist - i.e. you can't use one for bass signals in a hi-fi system,
but I presume in a HT context with some judicious filtering
you could get away with it at extremely low frequencies.

I forget the name of the company (maybe ADC?) but they made what was called a "sub-harmonic synthesizer." It was 2 channel and built for home use. They show up on ebay from time to time.

That has been my experience, too, but it could be simply because no one (that I know of) has tried all that dilligently to do a good job.

I've wished for years that a decent-sounding clock divider / half-octave generator did exist, as there are many recordings that could benefit from this.

I believe that there are TDM plug-ins that could be used to accomplish a similar function if you are (re)mastering a digital recording on a PC.

Or maybe a sampler synchronized to play one octave below would do the trick, with the output passed through a high-cut filter and mixed back into the main output.

The DBX 120 was somewhat polyphonic by using six bandpass-filters and six dividers foollowed by filtering again. This is still quite coarse. Irf you want to do it with a finer resolution this would mean quite some effort.
It would be possible however to do such things in the digital domain (the way harmonizers work).

Hello sreten,

I play bass as well, and I also have an octaver. It's really cool on some tracks, although it does limit your range somewhat, when playing lower than C on the A string tracking isn't as good as I would want it to be. I hear the newer units are better at this though (I have an old Boss stompbox octaver).
Couldn't agree with you more on guitarists

which is the best/would you suggest?

Most of these devices work by fooling the perceptual system rather than creating more bass...

They synthesise artificial harmonics of the original bass notes, add them to the signal, and then your ears and brain fill in the missing bass notes, making the Bass seem louder and clearer. After all, the last thing you want in live sound is to create more low bottom end that needs more big heavy amps and speakers, when you can just play with peoples's heads.

The original, (analogue, I think), Sabine and BSS units were pretty good, and should be available dead cheap S/H these days.
