Hello pd community!
I am actually doing a project involving a raspberry pi and pure-data, the aim is to create a sound level meter that calculate the equivalent level of the sound in dB (A-weighted). Basically, it is just a stockage of the level every seconds and ponderate on a 15mn basis. [if you don't know what is it : http://www.engineeringtoolbox.com/equivalent-sound-level-d_721.html]. The input~ will be provided via the wolfson audio card and the calculation on pure-data.
I started to create my patch but i struggle a lot, i would like to know if anyone would know existing patches that are used for that application : sound level meter, dbA filter, level stockage, any acoustics measurements,....
Anything could help
Thanks in advance!
