Special sound to improve speaker quality - Best Audio Burn-In Tracks

- **Usage and Volume Setting**
Please start playback after setting the volume to a low level. Once you start to hear a sound that rises in a surging manner, set the volume to what you normally use or slightly louder, but do not set it to a high volume that causes distortion. The sound includes tones that may be painful to the ears. It is not necessary to listen to the sound, so consider moving to another room or wearing earplugs to avoid hearing it. Although headphones or earbuds can be used, there is a more optimized sound source available, so we recommend using that instead. It takes several hours, so please use repeat playback. Refer to the instruction manual of your app or device for how to set up repeat.

- **Required Time**
The time required varies greatly depending on the device. Stop at a convenient point, such as 30 minutes or an hour, and then check with music or videos you are familiar with. In some cases, you may feel a change in as little as an hour. Once a certain level of change has been reached, you will hardly notice any further change in the sound. There is no need to do it all at once; you can divide it into sessions of 30 minutes or an additional hour at your convenience. It is okay to stop midway.

- **Audio Burn-In**
By utilizing various waveforms, frequencies, and noise sounds to improve the physical movement and flexibility, we bring out the potential of audio equipment. This is true not only for devices that are just starting to be used but also for those that have been used for some time. The audio has been primarily optimized for small to medium-sized speakers, car audio systems, TVs, soundbars, and Bluetooth speakers, focusing on their size and playback frequency range. The bass range starts at 30Hz, and for the high-resolution version, the ultrahigh range extends up to 45,000Hz, covering the characteristics of most speakers. While general speaker burn-in can require tens to hundreds of hours, this audio is designed to induce changes more efficiently, with noticeable changes possible in just a few hours. Please use it during times and conditions where it is okay to leave the sound playing. If you have pets, avoid using it in the same room to prevent causing them stress.

If you have already experienced a variety of sounds or if the manufacturer has already performed burn-in before shipping, you may not notice a significant change in sound.
