Well, not quite ...

Lucas' method of using [soundfiler] to get a (really long) soundfile's 
length still loads the complete file into RAM, as it would into an 
array. (i'm talking a 60 minute long audio file here)

This has 3 drawbacks:

1.) audio dropout while loading, depending on the file's length
2.) can use huge amounts of RAM
3.) takes much longer than [soundfile_info]

attached is an example patch that illustrates both approaches.

(use the same long soundfile for each method to see what i mean)



then again: since i use IEMLIB regularly it's not that much of a hassle. 
it's just not plain vanilla, that's all ...


best
