A while back I got a new toy: http://www.zoom.co.jp/english/products/ps04/
Brought it to my daughter's school corps autumn concert. I had no problems until the drum corps started. 20 drummers in a row gave us around 110dB in row 4... The recording level was too high or the used mic was too poor.
Which filters can be applied to improve the recording / remove the distortion?
