Hi Product Hunt community I’m excited to share HertzKit with you all. I wanted to build a simple, clean, and fast web utility for anyone who needs precise audio frequencies without heavy software or intrusive ads. Whether you are a music producer looking to test a mix, an audiophile calibrating your home theater, or just someone trying to clean water out of your smartphone speakers with low frequencies, HertzKit is built to do the job directly in your browser. It’s completely free and requires no signup. I’d love to hear your feedback, feature suggestions, or what tools you’d like to see added next! Thank you!
