Re: FLASH: Compressing voice audio for flash?

[Carterspot]

There are a lot of approaches to audio compression - The first standard 

method is to use dynamic compression  - not data compression, to increase 

signal to noise ratio. 


I wonder if it's a really good idea to whack somethng down to 8 bit though 

before Flash takes it down to 5, 4 or whatever lowly bits are left. 

Theoretically, if you have more bits to throw away during the final 

compression, you will get fewer noticeable artifacts. Cutting to 8 bit and 

then compressing again in Flash is going to give you more garbage in, and 

hence more garbage out. At least it seems that it would.


SF is a great tool - I want to know some of your tricks!
