@ mabus627: agreed, there has sadly been a significant amount of misleading info posted wrt digital signal processing fundamentals, esp regarding sampling theory and quantization. the "24 vs 16 bit myth exploded" thread is a notable example.
Hence the link provided to Pohlman (commentary and link to free sample on books.google:
http://www.head-fi.org/forums/f133/2...ml#post6161651) for access to a technically-correct intro... one which is reasonably digestable for those who have been smart enough to avoid an EE education (me, I was deluded enough to go the BS/MS/Doctoral studies EE path, and started working in pro audio equipment dsp hardware design in the early-80s. should have stayed an actor, different type of fun).
Principles of Digital Audio (Pohlman,
Amazon.com: Principles of Digital Audio (9780071441568): Ken Pohlmann: Books) is well worth reading (and buying) for those looking to get a reasonable (and correct) foundation in concepts of signal processing, data conversion, etc. as applied in the audio world. good info on quantization error, quantization distortion and how that leads to performance metrics.
Another good option: many good resources in general on the Analog Devices website, and their Data Conversion Handbook is a fine choice (
Amazon.com: Data Conversion Handbook (Analog Devices) (9780750678414): Analog Devices Inc. Engineeri: Books -- excellent bibliographies also, great resources to many of the seminal papers of signal processing theory, quantization error, etc.)
@ Arjisme: no arguments required. scientific and engineering fact concerning sampling theory and quantization is simply that: fact.
more helpful than "argument" is to help people to learn, and directing them to actual fundamental resources gives them the tools which can be used and later revisited as reference (as opposed to burning time in the all-too-common thread rhetoric and defensive outpourings ie by those prolific posters who finally get around to admitting that they don't understand the underlying math of signal processing, or the underlying technology in converter design)
try these: Pohlman (see links above); Understanding Digital Signal Processing (Lyons,
http://www.amazon.com/Understanding-...p/0131089897); fundamental texts on sampled-data systems ie Discrete-Time Signal Processing (heavy stuff, but definitive -- Oppenheim/Schafer
Amazon.com: Discrete-Time Signal Processing (3rd Edition) (Prentice Hall Signal Processing) (9780131988422): Alan V. Oppenheim, Ronald W. Schafer: Books)
