Hi guys,
is there a way to calculate peak level for a tons of file and output a txt file?
Something like..

for each file *.wav in this folder do
ffmpeg/sox/... --peak-level > report.txt
end

the report.txt should be something like:

file1.wav -5dB
file2.wav 0dB
file3.wav -15dB

My problem is looking for the TOOL (linux would be better), some cmd tool with that function... only the max peak!
