Mp3s -> Small, Yet High Quality

I only recently discovered the full potential of MP3s or MPEG-1 Layer 3. Before, I would download them from the 'net and the average one would be around 5MB.

Well, I did the following:
1. Ripped a track from CD-DA, in my case, "In Da Club", by 50 Cent, at 1411Kbps WAVE, using RealOne Player.
2. Downloaded Total Recorder by High Criteria from here and installed it.
3. Open ripped WAVE with Total Recorder and exported it. Selected option "MPEG Layer-3, 24 kHz, Stereo (MP3 encoder supplied with Windows XP, otherwise LAME encoder required).
4. Progress stated and afterwards found that my original 40MB WAVE was converted to a 1.29MB MP3! WOW!
I tried it out in WMP 9 and I couldn't tell the difference between the original file!

It was proabably because your bitrate for that file was really low.

Yea, that REAL tip :lol:

Like we know that mp3 was the best encode for music for decade, that why mp3 was so popular around the net for everyone to download. It can fit in small spac but yet fill with good quality sound!!!!

I guess this can be tip for music then :blink:

I assume you guys havent heard of MPEG-4 or mp4.
This format is even MORE compact than mp3 with virtually the same
quality of original when recorded at 128kps.

Its not popular now but AAC encoding which encodes files
into mp4 will probably be widely spread soon

u could also use ner mp3 pro encoder

....NO mp3 pro sucks big time..... it doesn't have its own extension and the quality isn't as good as an mp3 file. And an mp3 file is already very small

Like I said, it was 1411Kbps around 40MB.

i don't think many people will download them 40mb is to big for me!!! Can you tell the difference between them and a mp3 at 192Kbps, i use final scratch (Check www.finalscratch.com) when i dj and as long as its being encoded right a mp3 at 192Kbps sounds the same quality as it would if i was playing the cd or vinyl

I very much doubt that your 1.29mb .mp3 is the same quality as your 40mb .wav because I very much doubt you managed to retain anything like 1411Kbps bitrate.

mp3 is a "lossy" compression, which means you HAVE to lose something to make it smaller, 192Kbps is generally regarded as the bitrate which cannot be distinguished by the human ear from the original, I suspect your .mp3 has a much lower bitrate than that however... sorry!

Yeah, all you did was lower the sampling frequency. There is a loss of sound quality involved, but perhaps the song you chose didn't make it very obvious. Of course, what's the bitrate?

Read this for more info: MP3 Compression Standards; Sampling Frequency and Bit Depth.

QUALITY is what it's all about people!

Size does not matter in this case hehehe... :D

Actually, I have downloaded a 40 meg WAV file. It does sometimes improve sound quality, especially with classical music, which can render awfully in MP3 format.

The key is going mono. I've messed around with recording at really low bitrates and found that, if you do it in mono as opposed to stereo you can compress an hour of music into a 3mb file. You'll get a little extra noise but if you rase that so that it is about 10mb, you can't tell the difference between that and a regular CD. In my opinion mp3s could be smaller for all but the most serious audiophile.

I don't know how serious you'd have to be to prefer stereo to mono?
it's a bit flat and lifeless after generations of listening to 2 channel, 4 channel or even better.
