I shall be using LAME & EAC to rip my audio cds. http://mp3.radified.com/

But for mp3's that I have downloaded I would like to test them for quality.
Is there any audio analysis programs that you can recommend that I can run
my mp3 through to ensure they are upto standard and fix if possible.
I recall sometime ago a "spectral analysis" program for this sorta thing.

Im looking for a more "technical wizard" sort of apporoach to this rather than
me listening to them to ensure they're upto standard.

Cheers, Yasmin

you can't "fix" an mp3 file you downloaded, or any mp3 file in that matter.
mp3 is a lossy compression technique, whatever details that is lost is gone. its simply deleleted, removed, and no program can "fix" or "recover" that lost portion.

as for checking whether the mp3 is up to par, IMO, your ears would be the judge of that. no program can tell you how your music sounds, afterall, in the end you are hearing it

The short version: try the spectral analyzer in Cool Edit Pro (http://www.pcworld.com/downloads/fil...id,2920,00.asp) or EAC (http://www.exactaudiocopy.de/), or use your ears.

Do some ABX testing and try to find when the compression becomes transparent to you (cannot tell from original).

Hi Daroid

good links! I'll check them out.
I wanted a program that can give me a visual analysis of what is missing in
the file. So i can redownload the file from another source or recopy from
another audio source such as eg cd as an alternative to vinyl

Spectral analysis is only good for determining whether there is a lowpass or not. If you have an MP3 with no lowpass applied, you are guaranteed to have inferior quality (especially true for lower bitrates).

To be honest your ears are probably better for judging quality than any readily available spectral analysis tools. Basic tools can show you how the sound has changed, but they cannot show whether you will hear the differences or not. It's a bit subjective as well, for example some people are more sensitive to high frequencies so low pass filtering will sound worse for them. Personally I'd second what breez says about doing ABX testing.
