MP3 vs WAV (not a re-run)...

...but a question i've come up the last 2-3 days..

OK, you open your favorite mp3 converter, you choose your favorite encoder, AAAND u choose variable bitrate (instead of constant), continue choosing the best settings, such as 'best quality', 'real stereo' etc..

Now, if i'm not mistaken (if i am, please correct me), when variable bitrate is chosen, the encoder is supposed to calculate, decide and encode the selected WAV using the most proper amount of bits needed per second (or smaller time fragments)so the quality stays as good as it can be, right ?

Q1: why a constant bitrate of 320 or 350 should be considered as better (and not just the same) quality than this variable one i mentioned above ?

Q2: if you now create an mp3 using one of your tracks, using variable bitrate using the settings above, you'll probably have a 192 to 256kbps mp3 with a 224kbps as rms value. So then, could constant bitrate on 320/350 be lossless indeed ?

those are my first 2 questions.
ps. i don't know sooo much about mp3 encoding (nor i'm interested to have a PHD on it ), so i expect answers and corrections, not critics.
thank you

hm..i guess its about less space usage of the mp3..if there are long breaks and stuff where is not much going on..it takes less bytes to replace it and therefor the end file will be smaller with same quality.jmpov           -------......-------...-..-..-..-.-.-.-.-

As I understand it you choose a target bitrate when using VBR, say for example LAME with the -V2 switch should be around 192kbps.
The encoder will then aim for that as an average for the whole track but can reduce more data when there is a less complex signal or silence and use a higher bitrate when the signal is complex.

This mean that you get more quality per kb used compared to CBR where even silence will have to use the same kbps as the complex peaks hence wasting bytes.           (``·.¸(``·.¸(``·.¸¸.·`´)¸.·`´)¸.·`´)
