There is a way to...

post #1 of 8
Thread Starter 
REALLY tell the quality of an MP3 song beside the kbps ??

Like a program...application...analysis...number...someth ing

the question came from my music library....some 320kbps songs sound superb....but others sound very low...muddy...

so there is a number or data or something to determine the real quality of an mp3 song ??

thanks

no matter what a mp3 is a compressed version of a song.
wav/flac is a higher quality file.

generally a larger mp3 file will be better quality, and kbps too.
if the song you get sounds muddy someone stripped it down (so say got a 96kpbs) and then is trying to add layers again by labelling it 320kbps.

Exactly this. Congratulations on your first rep.

You should know since you ripped it from a CD, right?

This is correct. FLAC is also compressed. Flac is lossless were mp3 is lossy. Its not the compression that makes the mp3 lower quality its the data the mp3 decides to delete before compressing the file down. So a 60mb wav = a 10mb file after data is removed = 6mb mp3 after compression and flac 60mb wav = 40mb flac after compression.

Generally is the key word here.

A file could have been upconverted thus making the file larger with blank space, yet keeping the lower bit rate audio.


Also for programs there are a tons. The only ones I have used have been for wav formats. Just look for audio analyzers. Either way as a general rule you will see when analyzing the file, that lower bitrate songs will have the higher and lower frequency ranges cut off.

it depends on the mastering and production as well.
