How can you tell if a cd is lossless

[whatever]

I came across a few bootlegs on cd yesterday.

how can i tell if they are lossless or not

[Andrei]

i use cool edit

you have to convert 1 track from cd into *.wav

then you have to open file with cool edit and search in menu for "frequency analysis" (i think it's alt+z)

i'll post the pictures of lossless and mp3-sourced files, when i get home

(you can also use EAC, but i prefer cool edit)

[Andrei]

as i promissed :)

you have to use cool edit.

first of all extract a one track from the cd (in *.wav) with EAC (you can download it here http://www.exactaudiocopy.de/ - every good lossless trader uses this software to save the tracks from audio cd to pc)

then you have to open cool edit -> insert wav

then you have to click on: "switch to singlewaveform view"

then alalyze->frequency analysis this is what you see

Lossless CDR (http://lampix.htl-tex.ac.at/~aum2003/bsp2.jpg)

why ? well, forget "dB" on the right side, look at the Hz, you have 2000-20000 Hz (what a human ear can hear) and everywhere from 2000-20000 theres a sound

now the example of mp3 burned as audio cd (received it today from a trade :verymad: )

Mp3-Sourced CDR (http://lampix.htl-tex.ac.at/~aum2003/bsp1.jpg)

you see, it goes only till 12000 Hz (that's why mp3 are so small, the cut the 8000 Hz)

well, but there are many other examples. there are fm-broadcasts, webcasts (i think even worse, than mp3s), mini disc sourced shows (i think they go till 16000Hz) etc. the best source is DAT, it has 48,1 kHz (even better, than CD with 44,1 kHz), but don't forget, we can only hear from 2000 to 20000 Hz :)

the one example is my digital voice recording thing (don't know exact name). i made a short recording and converted it to wav and here's what frequency analysis showed

you see, it goes only till 8000 Hz

hope it helps :)

[Andrei]

i'm glad to hear that :)

i forgot to say, that cool edit isn't free, but if you want i can upload a "free" version on my server :D (it's about 10 mb)

[Watson]

wouldnt mind a wee shot of cool edit :D

[whatever]

yeah cheers that would be cool

[Andrei]

ok, will upload it tonight and post the link here

[Andrei]

and here it is :)

http://lampix.htl-tex.ac.at/~aum2003/cooledit/

just download all files to one folder and start *.exe, if you have some questions about that tool just ask me. i'm using it to detect mp3-sourced files and to record my songs :)

[Watson]

cheers bud

[whatever]

fair play andrei

[Eggbury]

sorry to be a pain in the arse but is it possible to have a link to download cool edit pro please? as the one on this thread does not work anymore

[Watson]

I will upload it later on for you mate

[Eggbury]

cheers mate, what is the best format to save a recording as then?

[Eggbury]

does anyone know the best sample rate and resolution to record music from my minidisc as?

i recorded it using both high rate and res and when i ripped it back off of the cd it looked like this:
