1-minute pure sine tones at 35 frequencies.
*KEEP VOLUME LOW. Audio signals (whether test signals or music) can cause hearing loss or speaker/amplifier damage even if you cannot hear them! NEVER troubleshoot while wearing headphones.
DO NOT USE if you are not professionally trained in audio/acoustics. Instead consider the Fast Audio Test • 1-Minute Audio Test fo... or Extended Audio Test • Extended Audio Test Fo... .

If that is not acceptable, you may not not use this videos or any videos on this channel.
- DO NOT TURN UP THE VOLUME if you can't hear the sound (unless you know what you are doing). Frequencies at the low range will be inaudible even if the speaker cone is moving. Just as with other bass-heavy music/tests, you could push your speakers past their mechanical limit if you're not careful.
- DO NOT USE AS A HEARING TEST. Go to an audiologist.
- DO NOT USE FOR TUNING YOUR SPEAKER EQUALIZER. At the least you'll need a calibrated microphone and acoustic tuning software/hardware.
This is a stepped sine wave test covering the full audio spectrum (but possibly limited by KZitem compression and your playback setting). 1-minute pure sine tones at 35 frequencies.
