[sdiy] companders

[Ullrich Peter]

Another solution would be the use of HighCom Chips or Modules from Telefunken.
But this option would only be interesting for Prototypes and not for series production 
as these chips are now obsolete.

But if you can find chips or modules they do a nice job.

Eumig and Telefunken TapeDecks used these modules and worked fine.

Ciao

I don't think the 571 style compandor works very well as a noise reduction system. The Roland SBF flanger uses this method and is still rather noisy.

Eventide used DBX type II noise reduction on their H910 and H949 harmonizers and the H910 delay sounds superb for a 10 bit system. Why not pick
up a cheap DBX encoder/decoder and try running the signal through that pre/post your delay?
