35 Sine Tones *For Audio Engineers*

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 for Stereo Speakers & ...   or Extended Audio Test    • Extended Audio Test For Speakers & Headphones  . *DISCLAIMER: You are fully responsible for the use and outcome of this video. Outlier Audio channel takes no responsibility nor owns any liability whatsoever for any outcome (whether damage, injury, or otherwise) from the use of this video or any videos on the channel. In no event shall this channel be liable for any loss or damage whatsoever arising from loss of data or profits arising out of, or in connection with, the use of this video. 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 YouTube compression and your playback setting). 1-minute pure sine tones at 35 frequencies. 0:01 10 Hz / Infrasonic 1:01 12.5 Hz 2:01 16 Hz 3:01 20 Hz / Lower Hearing Threshold 4:01 25 Hz 5:01 31.5 Hz 6:01 40 Hz 7:01 50 Hz 8:01 63 Hz 9:01 80 Hz 10:01 100 Hz 11:01 125 Hz 12:01 160 Hz 13:01 200 Hz 14:01 250 Hz 15:01 315 Hz 16:01 400 Hz 17:01 500 Hz 18:01 630 Hz 19:01 800 Hz 20:01 1000 Hz / Standard Calibration Tone 21:01 1250 Hz 22:01 1600 Hz 23:01 2000 Hz 24:01 2500 Hz 25:01 3150 Hz 26:01 4000 Hz 27:01 5000 Hz 28:01 6300 Hz 29:01 8000 Hz 30:01 10000 Hz 31:01 12500 Hz 32:01 16000 Hz 33:01 18000 Hz 34:01 20000 Hz / Upper Hearing Threshold All signals created at Outlier Studios using floating point arithmetic and dithered at 16-bit before Youtube upload.
