Distortion on CD

Reply from: Buck Turgidson
Date: 18 Feb, 13:04
I copied some files from a 20-year old CD and converted them to mp3, and
burnt them to a CD. Upon playback, there is some distortion.

Could this be the mp3 conversion process causing this? I use a tool called
"Audio MP3 Sound Recorder" which captures the soundcard stream, and then
converts it to mp3.

The conversion works fine on some things, i.e. it is not consistent.

Or, could it be some sort of copy protection?

Thanks for any help.

It certainly could be the mp3 encoding. What settings are you using?

Thanks. I switched to Lame, and it is much better. I do get some drop-outs
on the CD, though. Could that be the burn speed? The mp3 sounds file
playing it from the HDD.

Why are you using 'Audio REcorder', which is for capturing live streams, rather than
just ripping the CD to hard drive, then converting to mp3?

Probably from the mp3 conversion, but the original CD could be degraded but
effectively concealed on audio playback.

But whatever did you convert them to mp3 for in the first place ?

I think you lack a basic understanding of the conversion process. If you're
using your soundcard, you might as just play the cd out of your clock radio
and record it as an MP3 using your iPhone microphone as far as quality goes.
You're using the crappy soundcard's digital to analog converter (which
undoubtedly came with your PC) to convert a perfectly clean digital signal
to analog, then capturing the analog signal and using the equally shitty
analog to digital converter in the same cheap-ass soundcard to convert it
back to digital, THEN AND ONLY THEN converting the data to MP3, which was
all you needed to do in the first place.

A soundcard is basically a combination digital-to-analog converter and an
analog-to-digital converter. Unless you're converting digital to analog
(which you're not) or analog to digital (you're not) the process should have
ABSOLUTELY NOTHING to do with your soundcard.

What you want is a utility, and there are literally hundreds of free ones
out there, to simply convert the WAV file to MP3 using a few lines of code
and your PC's CPU. that's it. Go find one.

BTW, LAME *IS* an MP3 encoder.
