# 1. extract audio from all videos (assuming .mp4 videos).
for FILE in *.mp4; do ffmpeg -i $FILE ${FILE%%.mp4}.wav; done

# 2. use the first second of the first audio file as the noise sample.
sox `ls *.wav | head -1` -n trim 0 1 noiseprof noise.prof

# Replace with a specific noise sample file if the first second doesn't work for you:
# sox noise.wav -n noiseprof noise.prof

# 3. clean the audio with noise reduction and normalise filters.
