Audio Test Tones are for the the experts among our readers. These tones are best used in conjunction with external devices, such as a sound level meter or an audio spectrum analyzer. These test tones will help you testing your audio equipment, loudspeakers, headphones, and room acoustics. Some of them can even be used during hearing therapies.
Loud sounds can cause equipment/hearing damage with even a single, brief exposure. Always turn your audio system level down to a reasonable level, before playing our sound files.
Is AudioCheck free? Not for me. Your support keeps this site running. Any donation will be rewarded with • uncompressed .wav file download for every test (a download arrow will appear next to each sound icon) • increased durations and sample rates up to 192 kHz in the Tone Gen section • and, best of all, the removal of these pesky payment buttons below 😜
