I recently took some footage at one of my high school's baseball game, and one part from in the batting cages has some periodic loud noise in the background of balls being hit. I took a look at the various effects/filters in Audacity to try to make the noise softer (so that I could then in turn make the voices louder without clipping), but I didn't have much success. Just doing normalization on the file doesn't seem to do much either, likely just because of the volume difference between the voices and the sound. I uploaded an MP3 of the audio to http://dailygoob.com/uploads/VID00028.mp3 -- can anyone take a listen and give me some suggestions on what I could try next? Thanks.
