- Does anyone know how common the use of emphasis is on CD's?
-
- I'm in the process of building a DAC, but before I build in the extra
- circuitry to switch the emphasis in and out, I'd like to know if it will ever
- get used.
-
- Hunting through old copies of the AES journal suggests that emphasis
- was needed to compensate for low quality 14 bit AD/DA converters. I've
- read suggestions elsewhere that emphasis was only used on a few early CD's.
- Unfortunatel my present player seems to do the de-emph digitally, so
- short of bread-boarding an spdif reciever with an emphasis detector I've
- no way of going through my CD collection to see if anything uses it.
- Thanks in advance,
- Graham B
