Greetings, Please find attached a patch for the dynaudnorm filter. Under certain conditions, the output to the filter will clip at the beginning. This can be demonstrated with the following:
ffmpeg -filter_complex "aevalsrc=0:s=48000:d=0.6 [a_in0];aevalsrc=0.1*sin(440*2*PI*t)*cos(0.5*2*PI*t):s=48000:d=20 [a_in1];[a_in0] [a_in1] concat=n=2:v=0:a=1 [a_in];[a_in] dynaudnorm=b=1:m=100.0 [a_out]" -map "[a_out]" test.wav The root cause is that the FFMIN macro evaluates the minimum argument twice, resulting in the variable "input" getting incremented twice. Thanks, Andy
