WAV comparaison software

Hello,

I'm trying to find a way to compare two WAV files of the same sound
Could you help me know if there is any differences between them ?
Is-there any way to analyse these differences ?

You can use foobar with Binary Comparator plugin.

Try Audio DiffMaker:

"Audio DiffMaker is a freeware tool set intended to help determine the absolute difference between two audio recordings, while neglecting differences due to level difference, time synchronization, or simple linear frequency responses."

Thanks 

But i don't know what to do of the difference track... (.wav)

The only data on the .TXT file :
parameters: -2,417sec, 1,123dB (L),  1,122dB ®..Corr Depth: 62,0 dB (L), 62,9 dB ®

I've recorded with an old USB soundcard "As This Moment Slips Away" from the Joshua Redman The Bad Plus record.
And compared it with the original lossless file from Qobuz...

The error rate of the recorded file seem inferior to the world best CD players (approx 2% of reading errors)... do you find this interpretation right or not ?

Length mismatch : 6:52.399002 vs 6:52.606735, 18186796 vs 18195957 samples.
Compared 18186796 samples, discarded last 9161 samples from the longer file.
Differences found within the compared range: 36363286 values, starting at 0:00.000000, peak: 1.8229675 at 6:10.187029, 1ch

If the "record" you recorded from is a phonograph record, or any other analogue recording, you will get different data every time you record. Record it 100 different times and the probability is very low that any two will match each other, probably vanishingly small. Therefore, if you want to make any comparison to some purchased or otherwise obtained digital version, the only comparison that makes any sense is how it sound to you.

Thx for reply,
I try to understand a little more...
You are right, i've just compared two .WAV files extracted with EAC (accurate rip) of the same song of the same album... but two different CDs.

Tracks extracted from two different CDs are a different thing than multiple digital recordings from analogue sources. The two CDs could be the same and you could get exactly the same result from both.

The CDs could also be different, even though they are of the same album. The CDs may have been created on different manufacturing equipment, from different digital masters, or even be different masterings of the same music. Any of these might mean that the digital data is a little bit or a lot different.

If the two CDs are from the same digital master, produced in the same CD production run, they may contain identical data with identical offsets, etc. and you could, actually should, get identical extractions. If you don't, the extraction process, due to the condition of the CDs or due to variances in the CD drive(s) used to extract them, may result in small data differences.

With analogue source, even though you use the same LP or cassette, or whatever analogue media, for each recording you make, there will be significant differences each time the source is played because of mechanical tolerances in the TT motor, the tonearm bearings, the platter bearings, the phono cartridge, the power supply, wear of the source media, etc. Since the input signal to the ADC is different each time, the digital output will be different each time; multiple recordings will never exactly match each other. They may sound identical to a human, however, if the equipment is good enough.

Thanks for these precious informations 

The last comparaison was between the same album but with a 25 years old one and a new one.
There is no scratches at all but the substrate don't like growing old at all... only 25years    a vinyl or a HDD is a better solution to keep your music alive IMHO.

I've performed a test (with a perfect new CD) on all my computers CD readers (pioneer BDR/W, Samsung DVDR/W, Philips, Plextor SCSI... laptop ,noname...  ) there are no differences at all, the tracks are perfectly identical even with the cheapest old player.

All my homemade vinyl recordings are far from perfection... they are still magical even digitized and mp3-ized.

Probably you are comparing differing masterings of the same album. It's unlikely they'd actually sell the same CD for 25 years.

Yes, the waveform is a tad different... and not the same length.

If you actually want to compare different masterings rather than the same file, you don't need software, just your ears.  Listen to both, pick the mastering you like best.

You read my mind.
But i need some data (even bad interpreted  ) to be totally convinced !

I don't know what data you expect to find.  No software can tell you what you'll like better.

Sorry, it was a joke
