It looks like -b and -B will constrain the VBR.
Anyone ever play with -q?

Also, does anyone else listen to streaming radio and have any suggestions for getting the best content?
The -q is for Analog Quality, it is over ridden by -V0, -V2 .. etc, I do believe.

====================
algorithm quality selection
====================
-q n

Bitrate is of course the main influence on quality. The higher the
bitrate, the higher the quality. But for a given bitrate,
we have a choice of algorithms to determine the best
scalefactors and huffman encoding (noise shaping).

-q 0: use slowest & best possible version of all algorithms.

-q 2: recommended. Same as -h. -q 0 and -q 1 are slow and may not produce
significantly higher quality.

-q 5: default value. Good speed, reasonable quality

-q 7: same as -f. Very fast, ok quality. (psycho acoustics are
used for pre-echo & M/S, but no noise shaping is done.

-q 9: disables almost all algorithms including psy-model. poor quality.

I think -q is independent of -V.

-V is for adjusting the amount of bits to use in the VBR encoding.
-q is for adjusting how long the algorithm should search for optimal compression (huffman encoding) and minimimal quantization noise (scalefactors). This site has some info at the bottom: http://ntrg.cs.tcd.ie/undergrad/4ba2...oup10/mp3.html

Not sure how much longer the encoding will take though, and if there is even any noticeable difference.

Compression

- Lame encoded it is!

- Beacause everyone on here has convinced me.


I reckon the sound file is moving so fast you can't really hear the difference. But the difference is there.

The algorithmic compression of a 90mb WAV to a 9mb Mp3 would have to have lost a LOT of the nitty gritty stuff, which is basically what I live for & a lossy file can never be high fidelity by definition - but also even with a tweaked ipod and amp and great headphones - a portable is still a portable.

Its a hard concept buying so much equiptment for my portable just to listen to a lossy mp3 source file which I feel is fit for lesser equiptment.


But it seems its the only solution here.. At least thats until Sony brings out 'blue ray' like dap players which store 25 gig per disk -think of it a blue ray disk stores 25gb on one layer! blahahahahaha But that wont happen soon and even if it does who knows how much juice it would take to run a portable like that. (wakes up)

Ofcourse it can be. As long as it's transparent to your ears it is. You can try some ABX test to check whether it is. ( and unless you've done listening tests before you most likely will not be able to hear the difference between a -v0 encoded file and the lossless one.

I do however not recommend lossy files for archiving, but on portables it's preferable by far.

x2 . I use FLAC -4 for Computer archiving, and LAME -V2 or -V0 for portable use.
