So I'm a little late to the party :)

In preparation for my upcoming trip I treated myself to a portable CD player. It does MP3 files. I'm a geek so I had to investigate. I'm amazed that I can fit 15 of my favourite CD's onto one CD by converting em to MP3's. And I can't hear any degradation in quality (I did 192 KHz conversion). My playlist? Akhnaten - Philip Glass - 2 cds Satyagraha - Philp Glass - 3 cds The rise and fall of the city of Mahagonny - Kurt Weill - 2 cds Arnold Bax Symphony 1 - 1 cd The Photographer - Philip Glass - 1 cd Shaker Loops/Light over water - John Adams - 1 cd Ernst Moeran Symphony in G - 1 cd Mahler 8th Symphony - 2 cds Harmonielehre - John Adams - 1 cd Different Trains - Steve Reich - 1 cd Wow!!! You don't even want to know what went onto the other cd :) Rob Manderson http://www.mindprobes.net You have an eight-ball and Tommy wants to buy two grams.

Isn't 192Khz sampling a bit overkill? CD's already have a 44Khz sample rate which gives them a 0-22Khz frequency response. (Remember Nyquist?). Besides, you probably can't hear anything about 20Khz! Marc Latest AAL Article My blog Join my forum!

Just so you know, 128k is CD Quality, so you won't hear any degredation on that either. And you just mgiht be able to squeeze a few more songs on that CD.

128k is MARKETED as cd quality I personally hear the difference quite good. for 192k the difference is almost unnoticable (at least on my stereo) for the in my car I use 128K but at home I can't stand the flat sound that results compared to a real CE If you're copying classical material I would go for 192 k even in a car :)

You're comparing apples to oranges. CD quality audio is PCM audio sampled at 44.1Hz a second using 16 bits per sample on two channels for stereo sound. What you're talking about is a compression sample rate for MP3s and WMAs and not what you actually hear. What you hear is the result of the compression's sample rate. Jeremy Falcon

I'm using Dolby Digital 5.1 in my truck and I honestly can't hear any difference. Maybe I'm going deaf :~

or maybe it's 192kbps :)

On MP3 at 128k, I tend to find that some material acquires a distinct 'phase' on it. Encode Lenny Kravitz' 'Are You Gonna Go My Way', which has a lot of crash cymbals in it, to 128kbps MP3 and play it back. The cymbals will sound very odd (unless encoders have got a lot better recently...). I think I had to go up to 256kbps to get an acceptable result. ISTR that the same track is perfectly acceptable in 96kbps WMA 9 - but this might vary for other tracks.

I'm with you. 128 kbps may not be as good as 160 or 192, but I can't hear the difference, and I certainly appreciate the smaller file size. :-) Regards, Alvaro
Hey! It compiles! Ship it.

No, I meant just that. Media Player on the Pocket PC doesn't pause MP3s (it effectively behaves as Stop), but does pause WMAs properly. Normally I'd prefer MP3s (being a more open standard), but I don't have a problem with WMA if I'm encoding from another form of media I already have available (like CD) -- Ian Darling "The moral of the story is that with a contrived example, you can prove anything." - Joel Spolsky
