I'm somewhat of a relic of an audio enthusiast or audiophile. I got my start with a turntable based system I bought with money earned as a paperboy about 35 years ago. But I think I have some questions about MP3 and wav playback that others may have as well. Here they are:
1) Will a good DAC or Soundcard do anything worthwhile, $200 worth, for MP3 playback?
2) If one "plays" an 128k MP3 file, I assume the computers motherboard or soundcard will "see" a 128k signal.
Also, that those devices will convert the signal to an analog signal put out through the analog out jacks. But, what signal should I
expect as output from the spdif jack?
3) I am under the impression that "red book" CD means a 16 bit sample taken 44,100 times per second of an analog signal, is this
correct?
4) MP3 files are composed of what size samples taken how many times a second?
5) Oversampling, in theory, can not improve sound. Am I correct?
6) Radio Paradise and Cinemix streams are so called lossless streams, correct?
7) In conversion of an analog signal to an MP3 file, not all sound frequencies are treated equally, correct?
8) Playback of an MP3 file requires a codec, right? Is this software that converts the file into an analog signal? Or, software that
converts the file into another digital signal? Or, non of the above.
9) Given that outside of Radio Paradise and Cinemix, all the music I listen to is MP3 quality, would my next audio dollar be better
spent on a headphone amp or headphones rather than a DAC? BTW, I currently use DR 150 headphones
and have a set of T50RP 'phones on the way.
10) Can the difference between wav files and MP3 files be stated in terms of sample size and sampling rate?
And, if so, what is it?
Thanks ahead of time for your feedback!
