Oh, crap. Okay, so I downloaded the aucdtect task manager and must admit I am lost. I am using a MAC and am not sure if I have run into compatibility issues or some other obstacle. I don't even know where to start... would someone please help me?
You don't have to shell out cash to get a decent portable media player: Check around for iRiver's H100 or H300 series DAPs, add rockbox, and have hours of listening pleasure for 45-75$USD.
Okay, so I ran the auCDtect Task Manager on my laptop PC. I downloaded Nirvana's In Utero in FLAC format and ran it through. Under the 'conclusion' header it said "CDDA 100%" and it said the same thing when I went to 'details' and looked at the spectroprogram. So, I am assuming that means the files are all authentic FLAC? Would I be correct in that assumption?
sorry, digital neophyte questions - what are the diffs amongst the file types in iTunes and which are acceptable from an audio quality (or any other) standpoint? i can import into iTunes with the following encoders: AIFF, AAC, Apple Lossless, MP3, WAV. which formats should i import my cds into iTunes with, and which should i use to put tunes onto an iMod, a nano, or to burn a cd with? thanks.

For some reason when usingauCDtect task manager, load up an album and hit play, they get to 100%, then under "Status" it says "ERROR" and under "Conclusion" it says "CDDA100%." Anyone know what's the go here? It's all highlighted red also.
is AAC good enough for something like an iMod (as opposed to a less refined set up such as a stock ipod sans amp), or would ALAC be beneficial for this application?
I would say it depends on how you use it, if it for mobile use in transports, office (background noise + impossibility to concentrate on the music), I would say certainly AAC is more than sufficient.
For critical listening, it depends on your gear and your own preferences, you could download foobar and do an easy ABX to be sure.
i came across this report whereby the reviewer compares different sources, and file conversion schemes on a good stereo. the results are interesting, especially his comments about aac vs mp3 both @ 320kbps. :

Could it be possible that players with lossless support (flac, alac, whatever) won't deliver the true lossless information? I was looking at the tech specs for the 5th generation ipod classic and under the heading "Digital Player" there was a section entitled "Supported Bit Rate" with "16-320" written next to it.
Don't even lossless files have a bit rate? If so, then doesn't that mean your lossless files won't be any better than your 320 bit rate mp3's when using the 5th generation ipod classic (and possibly other DAPs)?
Keep in mind that I am a newb and speculating of course.

I'm having the same issue with the conclusion showing as CDDA 100% but the stats showing "ERROR" and the line is highlighted in red. Did anyone solve this issue? Is this software still worth using?

Welp, I played around with it and decided that it's probably not worth using. After some testing I noticed that it's not accurate with ambient music, so it can't be trusted in general. I tried a few for-sure lossless rips that I have ripped myself with EAC (Tangerine Dream - Phaedra, Stars of the Lid - Refinement and Aphex Twin - Ambient Works II), but auCDtect marked the files as lossy.
Even more confusingly, the results from this program often contradict those of AudioChecker and/or AccurateRip.
Overall I've learned that there really is no way to verify downloaded files. All these programs actually accomplished is make me paranoid. The best you can do is rip your music yourself or at least make sure your downloads have valid EAC logs.
The "problem" with programs like auCDtect is that they are like us.
Low bit rate MP3 they can detect.
High bit rate MP3 they can not differentiate from the original.
As far as I know there is no reliable method to differentiate between "real" lossless and fake by analyzing the spectrum.
What you need is a program calculating the MD5 and compare this with the value of the MD5 in the AccurateRip database.
If it is lossy it sure generate a different MD5
Maybe dBpoweramp or EAC can do this.
Never tried it myself.

I have all file types within my iTunes Library, including some Aiff at 24/192. With today's computers, running out of space is no longer an issue so why not download such files? For one thing these files will cost more money. Sometimes twice the price of an album downloaded from the iTunes store delivered as an AAC 256 file. Now if you can hear a difference, that's to say, if a 24/192 file sounds better then go for it. But, remember if you are sending your iTunes to home speakers, you will need to get a DAC which can process that type of file, unless you are running analog out from your computer. My DAC will only process up to 24/96 so that's the highest quality file type I can appreciate. It was for awhile the way I bought online music. Some of these downloads are AIFF and some are ALAC. I can not discern AIFF is better. Thing is, I can not discern either AIFF or ALAC at 24/96 as being better than AAC downloads from the iTunes Store. So, for the most part , now I just download AAC from the iTunes store saving money and space without any sense of not hearing all there is to hear. In fact, in comparing AAC to SACD, I can not discern SACD is better even when hoping for that outcome. After all I paid big bucks for my SACD player and even more for my collection of SACDs. The bottom line is I bellieve CD quality is going to get you all the quality that you can appreciate. So, for assured happyness, for downloads, you could go to HDtracks and download CD quality files in ALAC and if you are importing CD's to your iTunes Library, you could select Aiff with 16/44 processing. ALAC is suggested for downloading since the playback result is 1, indistinguishable from AIFF, 2. less time consuming to download, and 3. takes up less space in your library.
