Hello, I was just searching the archives to see if I could do some statistical analysis of recordings. I see Edgar recently published an A-weighting filter and I've succesfully runi it as my first plug in. (Sorry I've only just joined the list so I only know you by the archives). At work I'm using audacity to measure noise levels, so I wonder if this has been done before. I'd like to determine L10, L90 and Leq of a sample. For those of you whose jobs are more interesting than mine, L10 is the level which is exceeded by 10% of all samples. Has this been done by anyone? Lisp is a foreign language to me so I'll need some time to get used to it. Thanks for any help, George |
