Okay, I deleted most of this thread, so I was waiting for another message to respond to, so unfortunately this will be out of place in the thread.
This is in response to Miroslav's idea about variable block sizes. I may be a bit out of my league here as I'm just starting to look at how the actual encoding gets done. But it seems to me that you could make a decent guess about when something "new" happens based on the second derivative of the signal (where the first derivative is the difference between a given sample and the previous, and the second is you-get-the-idea). Here's my rationale: high-amplitude, high-frequency sections are the hard ones to encode, or at least will work best in their own frame. Those characteristics imply a high first derivative. You want to put such sections in their own block, and boundaries of such blocks will be where the second derivative is relatively high. Okay, that's not quite right, since the first derivative will be negative about half the time, and large negative has the same effect as lange positive. So I think what you really want is the first derivative of the absolute value of the first derivative. Then there's the question of where to put the boundaries. Some trial-and-error is probably the best approach here. For files on which the above formula is consistently high, it will probably be desirable to set the limit high to avoid too much frame overhead. Hope this was interesting and/or useful :) . -- Brady Patterson ([EMAIL PROTECTED]) ------------------------------------------------------- This sf.net email is sponsored by: viaVerio will pay you up to $1,000 for every account that you consolidate with us. http://ad.doubleclick.net/clk;4749864;7604308;v? http://www.viaverio.com/consolidator/osdn.cfm _______________________________________________ Flac-dev mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/flac-dev
