If you can tell the difference between 256 and 500 Ogg Vorbis, you probably shouldn't be using Ogg Vorbis.
What is that supposed to mean?

Go with FLAC. That way you can preserve them on your hd and just convert them to whatever format you want when you move them to your player.

Try to see if you can hear the difference with for example Foobar with the ABX plugin. That allows you to test yourself, you can hear both tracks (the same song at different bitrates) as often as you like and then you have to guess which is which.

I was a little disappointed that I could not hear the difference between AAC 128Kbit/s and AAC 256 Kbit/s ...

I've got a iriver H140, ripped albums are OGG as well. 165-180kps VBR. Depending on your quality of headphones, I would suggest at least 128kps OGG..IMO you don't need to go above 192kps OGG for portable uses. For Audiobooks 96kps OGG is fine.

And considering the size of your HD you might want to fit more albums on, instead of fewer albums but in very high quality.

I created several MP3 VBR and OGG VBR at exactly the same size (40-320kps)..lower bitrate OGG beats MP3..but with 320kps I could not tell the difference. But since you're taking up more space per file, it's likely a much lower bitrate OGG will be equal to 320kps MP3.

What is the difference whether I go variable, or constant?

Variable adjusts bitrate according how complex that sequence is, and lowers it when there's silence of less complex pattern.

Constant will keep it fixed to that bitrate, even if there's 30 seconds of silence, or when there's hardly any complex patterns.

VBR allows you to use a higher bitrate, for actual smaller filesize compared to CBR at the higher bitrate.

Encode a file at 192 VBR and 192 CBR. The VBR will be smaller and sound better..so in effect you could use 160 VBR and be equal in sound quality to 192 CBR.

IMO it's best to do comparisons to get a obvious difference at really low bitrates, ie 128kps VBR v 128kps CBR. That'll show it up, so then choose your preferred bitrate with VBR.

Test it yourself

Jetaudio 6 rules. Use it to test any format and decide for yourself. It supports, ape, flac, ogg, mp3, mp3pro, mpc, real, wma. Also set the compression rate, vbr or cbr. Its all there, you decide what you like.

Not to mention a plethora of other formats (video, music, etc), i flat out love Jetaudio 6, not enough people use it around these forums. The differences between pro and basic are very minimal (a few EQ settings). If foobar is too complicated and open ended for you then jetaudio is your best bet by far.

Now that I'm reading this thread, I need to know if what I did makes any sense. I want SQ and not interested in saving space.

I have iriver120. I ripped cds with cdex onto wav file and downloaded onto the iriver.

Was that the best for SQ?

It takes just as much effort to rip CD's into lossy files as lossless files. If at some point down the line you decide you want even "better" sound quality b/c you upgraded your gear, you will be very unhappy to find out one can Never convert a lossy file to lossless/original quality. You would get extremely mad at yourself as you re-rip all your CD's AGAIN!

Rip your CD's into lossless once, and you can convert them to any lossy or other lossless files you want, even .wav. This is the way to go. Even if you need a certain lossy file type now for your portable, it's VERY worth it to first rip everything into lossless and use dbpoweramp to simply convert them to the lossy file you want, which takes no time or effort to speak of.

With hard drive prices plummeting by the minute, there should be no reason not to do this.

I'm sorry, I don't understand you. Did I make a mistake or not? Can I get better SQ ripping and filing differently than I did or not?

While some will disagree with your choice of cdex, wav will still give you the best sq, however, you didnt really conserve any space with the wavs, which usually is the point especially if used portably.

Conserving space isn't an issue now. I still have 11.5 gig left. I downloaded 185 tunes in wav files so far.

What's better than cdex and why?
