I've downloaded some mp3's which i would like to use for a mp3 cd. The bitrate of the mp3's differ but i would like to use one bitrate for those mp3's. The question is: Does it make sense to upgrade the bitrate (for example from 128 to 256) e.g. does the quality of the mp3 realy improve? Because i've read to following on the internet:
"Upgrading an MP3 to a higher bitrate is impossible. The only solution is to re-encode from the original source."
No, encoding an MP3 is like recording an audio source (the Wav file, or the CD). Using a higher bitrate is therefore like making a copy of your previous MP3. At best, it could be as bad, but some quality is eventually lost again. So it will sound inferior.
I'm redoing all of my music CD's to CD's of reputable manufacturers (ritek, etc).
Personally, I download my mp3's and convert them to .wma format 192kbps then back to .mp3 @ 320 kbps. This really brings out the quality of the songs. Louder without distortion, clearer, crisp audio, all that good stuff you expect from an official CD.
