Error implementing the AFFTDN filter with a noise type of w
Hello, I am trying to clean up an audio file which contains background noise using the AFFTDN filter with a noise type of white noise. I have not been able to find an example of the AFFTDN filter implemented and working. Based on other examples I tried this command line code. ffmpeg -i C:\Media\test.wav afftdn="'nt=w':om='o'" C:\media\test_clean.wav When I run this Unalbe to find a suitable output format for afftdn="'nt=w':om='o'": Invalid argument. Thank you in advance for your help. Tim Mason

We usually kindly ask you to show us the complete, uncut console output of your ffmpeg command. Though in this case:

You didn't tell ffmpeg that this section is a filter command. You need to prefix it with "-af", otherwise it is interpreted as the name of an output. $ ffmpeg -i C:\Media\test.wav -af afftdn="'nt=w':om='o'" C:\media\test_clean.wav You have too much quoting as well, though it does not hurt. You can also do: $ ffmpeg -i C:\Media\test.wav -af afftdn=nt=w:om=o C:\media\test_clean.wav (Use more quotation marks depending on content.) Cheers, Moritz
HI Moritz, Thank you for your assistance. I will make sure in the future to include the full console in my posts. This change in command worked for me.
