[foo-devel] peak amplitudes in sound files

[Ramon Gonzalez-A. <ar...@ma...>]

Dear Sirs,

Indeed peak amplitude info in Foo is rather slow. It seems incredibly  
much faster with sndfile-info.

Peak location is not always needed, but sometimes it is important  
(gives valuable info). I didn't know that the doc was wrong with snd- 
absolute-maximum. Actually I was always assuming it to be a pair, and  
I have some functions that use it with this feature.

Consequence number one, seems to imply loosing the peak location, if  
I understood well. This would be a pity for a number of cases. But  
if, snd-maximum supplies the peak location, as it does now, then one  
could play with both, depending on what one needs.

I agree, on the other hand,  with consequence number 2 (snd-maximum  
returns absolute maximum of channel and snd-minimum is removed).

Finally, having the peak info kept on the header would be rather  
convenient.

In other words, I agree with committing, if we can keep some way of  
having peak location info somehow.

Best,

Ramon
