I built these free audio tools because most of the stuff producers need to look up – compressor settings, EQ ranges, loudness specs, polar patterns – is scattered across blog posts and YouTube comments. These tools put it all in one place with no sign-up required. Pick a tool, get the answer, and get back to work.
