Do a frequency analisys. If it is cut at 16/18 Khz it MAY be mp3 sourced or FM sourced.

There is also little bips between the tracks even if it is done DAO, although some people have been known to be able to get rid if this is a wave editting program.

The little blips between tracks could also be that the person didnt split the show correctly. If they just used soundforge they may not have cut it on the exact point. Im sure dead explained this in another thread but i cant be arsed to look for it.

I should make a guide. You have to form an opinion based on a number of factors, since a non-mp3 sourced recording can have both dropoffs and gaps as well. I can't go into it right now but I'll try to write something about it later on.

Are you going to write essays on geeky audio-tech stuff like StArSeEd always does?

Totally agree but then again any trader who's gonna be doing proper recording within a mega bucks program like sound forge (for whihc i use all the time), on the most part know what there doing, and thus the blip is not present.

I didnt mean any offence at all, if you imagine the boundary right at the end, which makes it very hard to edit out the blip from the wav. You are only gonna hear the blip if the track is going on to another track recorded at DAO, so all you do is paste the two tracks together within soundforge go to the exact point where the first track eneded and zoom in, you will see a break between the tracks if you delete this then the gap is removed, thus allowing you to edit the boundarie then to record the cd all you do is put it into a program like winoncd 5 power edition which will allow you to see the wav file as a whole and place the track point whereever you want. Just a useless piece of info it still doesn't get around mp3 being absolutly dog and sounding as tinnny as the guy from the wizard of oz.

No, that's not mp3 sourced.

And with regards to splitting tracks on audio sector boundaries, just view the file in samples, and make sure the number of samples is divisible by 588. If it's not, and it usually isn't, cut off the appropriate number of samples to make it divisible by 588. After that, go split your tracks in CD Wave.

WOOT! A First gen copy of YKYR ! It was the comparison from this questionable WAV snapshot:

http://fatteningass.homestead.com/files/ykyr.jpg
to this Mp3-converted-to-WAV snapshot:

http://fatteningass.homestead.com/files/ykyrmp3.jpg

that convinced me that the questionable WAV file was indeed not from Mp3. Thanks for your input BTW.

Remember that certain TV broadcasts, FM broadcasts and low-quality recordings can also have drops. Its also possible to have mp3s with no drop or very little drop, although that's pretty uncommon in my experience.

TV & FM broadcast can be crossed out. as for low-quality, nah it sounds great. I do believe i got the real deal here though. thanks.
