Analogue or Digital

[Ray Stainer]

I need to know how the route and/or functions of the digital signals from
CD-Rom(s) to the external Speakers or headphone socket.
At present I get varying effects while trying to diagnose the differences depending on the type of source format.
My system works perfectly with all other audio eg. *.wav, *.mid etc..from any source other than my D: or E: drives.

hi

we need to know more about your system specs, as well as what is or isn't- happening (exactly)

Unless you use the SPD/IF connector (if so equipped) on your CD-ROM drive, the sound output through the speaker and headphone jacks is analog. Internally it's digital, but the sound card's RAMDAC converts it to analog before it gets to the jack. Hope I understood your question correctly. http://www.PCGuide.com/ubb/biggrin.gif

Well... The end result is ALWAYS analog. Speakers CAN NOT move in anyworld other than the analog world. Sound travels in waves that are produced by, in the case of speakers, a diaphragm moving from point A to point B which equates a sine wave... ie, analog.

Now... How things evolve in the recording process, I could go on forever. If you're talking about the perceived differences between analog media and digital media, that's an entire world of bebate in and of itself. The topics of said debate include but are not limited to sample frequencies, bit depth, solid state (resistors) vs. valve amplification (tubes), RMS, peak power for amplification... Do the advantages and conveniences of the digital media outweigh the sonic characteristics of analog?, 'bit loss' in the recording and duplication processes, etc, etc, etc...

As far as the conversion of digital information to analog information... The CD has all of the audio information stored on it in digital form (Ones and Zeros). This signal is then converted via a D/A converter into an analog signal and amplified before being slammed into the voice coil of the speakers.

I don't understand precisely what you are looking for here. Are you trying to 'diagnose' the different sound characteristics/quality of each type of file (.wav, .mp3,. aif, .mid, etc) from different sources (D:, C http://www.PCGuide.com/ubb/smile.gif? The difference between the sound depending on the source should be nil. However, there are VAST differences in sound quality with respect to the type of file.

I know I was just kind of 'throwing paint on the wall' there, but if I missed something, lemme know.
