SoundTest is a suite of free, in-browser audio tools. Test your left and right speakers and headphones, run a frequency sweep, generate any tone or DTMF dial tones, detect the musical note from your microphone, and measure ambient sound level in decibels. Everything runs client-side with the Web Audio API, nothing is uploaded, and there is no sign-up.
