Little Spacey

Hello,

I am attempting to replicate a certain Tangerine Dream sequenced synth sound that I am told uses BBD delay. Is there anyone who can tell me how BBD delay is different than a typical tape delay software plugin?

Thanks.

A bucket brigade delay (or BBD) is a type of device rather than the name of a particular one.

Here is a link to a description:

http://en.wikipedia.org/wiki/Bucket-brigade_device.

Being an analog device the fidelity of the signal degraded especially with longer delay times.

and multiple repeats. They were also limited in frequency response and could be a bit noisy.

(at least in the real world :-) ), but sounded less clinical than the digital delays which followed.

I hope this is helpful.

BBDs can also add analog aliasing to the delay line, just an interesting little tidbit since I always associate aliasing with digital. Essentially a BBD is a sort of analog sampler that holds a short amount of audio in a huge line of components (capacitors, transistors, something or other) with each one passing it onto the next until it reaches an output.
