SoniqTools

SoniqTools is a suite of free audio tools that run entirely in your browser — no uploads, no signup, no installs. You can analyze audio quality, convert between formats, extract audio from video, trim, merge, split, compress, normalize loudness, view spectrograms and waveforms, edit metadata, and generate tones. Because everything is processed locally on your own device, your files never leave your computer, so it's fast, private, and secure. It's built for musicians, DJs, producers, podcasters, and anyone who works with sound. Free to use and available in nine languages.
