Generate soothing noise

/usr/bin/play -q -n synth brown band -n 1200 200 tremolo 0.05 80
Substitute 'brown' with 'pink' or 'white' according to your taste. I put this on my headphones when I'm working in an "open concept" office, where there are always three to five conversations going in earshot, or if I'm working somewhere it is "rude" of me to tell a person to turn off their cubicle radio.

  • This command will generate white noise through your speakers (assuming you have sound enabled). It's good for staying focused, privacy, coping with tinnitus, etc. I use it to test that the sound works.

  • Full command: for f in input/*; do BN=$(basename "$f"); ffmpeg -i "$f" -vn "temp/$BN.flac"; sox "temp/$BN.flac" "temp/$BN-cleaned.flac" noisered profile 0.3; ffmpeg -i "$f" -vcodec copy -an "temp/$BN-na.mp4"; ffmpeg -i "temp/$BN-na.mp4" -i "temp/$BN-cleaned.flac" "output/$BN"; done This was over the 255 character limit and I didn't feel like deliberately obfuscating it. 1. Create 'input', 'output' and 'temp' directories. 2. Place the files that you want to remove the hiss/static/general noise from in the input directory. 3. Generate a noise reduction profile with sox using 'sox an_input_file.mp4 -n trim x y noiseprof profile', where x and y indicates a range in seconds that only the sound you want to eliminate is present in. 4. Run the command.

  • Generate a truly random password using noise from your microphone to seed the RNG. This will spit out 12 password with 12 characters each, but you can save this into a bash script and replace 'pwgen -ys 12 12' with 'pwgen $@' so you can pass any paramters to pwgen as you would normally do.

    TMPFILE="/tmp/$RANDOM$RANDOM$RANDOM$RANDOM$RANDOM" && arecord -d 1 -t raw -f cd -q | base64 > $TMPFILE && pwgen -ys 12 12 -H $TMPFILE $@ && rm $TMPFILE

  • This generates some powerful but relatively unobtrusive waterfall-like noise. Good if you need to get serious stuff done while your next-door neighbor is throwing a very loud party. You need the sox package installed.

What do you think?

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
