--alt-preset standard -b 96 ?

I have borrowed two CD's containing the story "The Hobbit". The CD's contains mostly speech, but also passages of background sounds and music. Hence a very broad range of complexity.

Of course I encoded the tracks with --alt-preset standard, but I got A LOT of 128 kbps frames. I canceled the ripping process, and ripped again, this time adding -b 96 to the commandline. I think I got a better distribution of bitrates, with this added parameter.

Here's a graph of chapter 12:

Now my question is: Does adding -b 96 break something in --alt-preset standard, or is it, for any other reason, not adivisable?

I'm not looking to reduce the size dramatically, but of course want the most efficient use of bits.

--alt-preset standard -b 96 ?

Hi,
Perhaps I got it wrong but I thought that the preset line should read --alt-preset 96 and not as you suggest.

--alt-preset standard -b 96 ?

Zalkalin, I've been using --alt-preset standard -b80 for my stuff.  In fact, when Dibrom was working on --alt-preset normal (a precursor to the new standard), it originally used -b80. 

I have some mono CDs that don't need the extra bits - here's a link to my conversation with Dibrom:

It's is not, it isn't ain't, and it's it's, not its, if you mean it is.  If you don't, it's its.

--alt-preset standard -b 96 ?

No auldyin,
Your command line would produce an ABR 96 mp3 file, but Zalkalin's question is about the minimal bitrate used for easy-to-encode frames. --alt-preset standard defaults to 128 kbps minimal bitrate.

--alt-preset standard -b 96 ?

Seems like -b 96 is no problem at all. I might just encode the rest of my CD's that way.

Thanks for the reply.
