I digitaliz my LP’ s (vinyl) to cd. First I used WAF. That makes 60 minutes of music on cd for every 60 minutes music on LP.
I try now to be more efficient by comprimeren of information to MP3. To my surprise its is still 60 minutes of music on LP is 60 minutes on cd Or my burning software. I expected less minutes.
How is that possible? Do I misunderstand MP3? What do I wrong?
Or do I have more than 80 minutes voor my cd?[/QUOTE]
a minute is a minute,
What changes is the ammount of bits the different digital formats take up on disc space.
When you convert LP to uncompressed “Date” Microsoft PCM/WAV format a CD will hold 702Mb of “data” or music in CDDA format which has a play time of 79min52seconds.
On the other hand if you burn the music to a CD-R as mp3 at a data rate of 320Kbits/sec the CD-R will hold 4.5times as much music (in terms of play time) compared to CDDA format.
If you convert your music to 160Kbit/sec mp3’s the CD-R will hold nine times as much music.
This is the effect of “compression”
