*How to use
First, a test tone is played for 5 seconds.
Set the volume to a level that makes this tone seem a little loud. There is no need to set the volume so loud that it distorts the sound.
After completing the volume setting, be sure to remove the headphones/earphones from your ears.
Do not listen for a long time even if you are using speakers.
The sound seems to disappear in the middle of the sound because high-frequency waves, which are inaudible to the human ear, are also played, but the output is still being produced.

*Required time
Although it varies greatly depending on the device, in many cases the speed of change is fast for earphones/headphones, and the change is often felt within 30 minutes to several hours.
Speakers have a wider range, so this is just a rough reference, but it is recommended to use several hours to several dozen hours as a guide. Please check with the song you usually listen to from time to time while playing it on repeat.

*About this audio
This is a burn-in track that specializes in improving treble sound quality.
Please try this sound for equipment that makes treble sound piercing, not extended, hard, reverb reverberation is thin, and sound field is narrow. It can be used for headphones, earphones, and speakers. For headphones and earphones, please remove them from your ears after setting the volume. For speakers, please do not listen for a long time.

*Specifications
High-resolution version is recorded up to 46kHz.
*The other version will be cut off at around 22kHz due to the specification of the format.

*What is burn-in?
Burn-in is the process of acclimating audio equipment that has not been installed for a long time.
The sound is hard, bass is not produced, voices are pulled back, treble is piercing, and the impression is different from the sound heard on the listening device... There are various causes.
There are many reasons for this, but one reason may be that the potential is not fully realized.
Just as freshly lowered clothes or shoes may feel uncomfortable at first, audio equipment with moving parts may show its true potential by "acclimating" to the environment.
Even if the equipment has been installed for some time, its potential can be brought out by continuously playing the bandwidth that is not usually output.

*This audio feature
In order to perform burn-in without affecting the bandwidth other than treble as much as possible, the lowest note is set at 3,000Hz and the highest note at 46,000Hz (cut-off around 22,000Hz for other than high-resolution version).
Sine, triangle, square, and sawtooth waves are followed by frequency-adjusted white noise, the hardware sounds of live drums, and the processed hardware sounds of a rhythm machine. All of them are optimized for high frequencies.
