Ghosthack - 13 Free Vinyl Crackles WAV [free]
Wav sample pack - 7 mb
A lot of producers use crackle sounds in their productions to create a special form of atmosphere, they combine it with reverb, delay or flanger and implement them deep in their mix. Famous examples are producers like Burial, Boards of Canada, Odesza, Clams Casino, old Trip Hop Bands like Portishead and many more.
I'm also a big fan of crackle sounds in my tracks and love to experiment with them. If you're into producing deep and calm music, give it a try!
