Sound Improver 3 silent

Sound Improver 3 silent is the noise for improving the sound quality of headphones and speakers, and can achieve sound quality beyond the manufacturer's expectations.
Since it uses ultra-low frequencies, it does not become noisy even when played through speakers.


User Manual
1. Turn off Audio normalization, Tone control and Equalizer.and set the sampling frequency to 44.1kHz.

2. About volume adjustment
For speakers
This noise uses an extremely low frequency of 6.48Hz at 19-31sec of the track. Adjust the volume so that the woofer stroke is less than +-0.5mm (1mm peak to peak) in 6.48Hz section.


If the stroke is too large, it will cause the coil to break. Therefore, please refrain from using a subwoofer those stroke amount cannot be checked.


For headphones
The recommended volume range(amplifier volume position, not loudness) is the volume position you normally listen to.


However, in the case of streaming services, the volume of the audio source may have increased due to audio normalization. If you hear this noise at the same volume as other music, it's definitely normalized. In that case, lower the volume by about -11dB to get the proper volume. Or use the download version.


3. Repeat playback and end when the sound quality no longer changes.



About maintenance
Sound Improver 3 is designed to effectively remove distortion of the diaphragm by taking into account the symmetry of the waveform, but with general music waveforms that lack symmetry, distortion will be gradually applied to the diaphragm, and gradually degrading the sound quality.
Even if the sound quality deteriorates due to distortion in the diaphragm, Sound Improver 3 has a breaking-in effect on the diaphragm, so a certain level of sound quality can be maintained. However, if you want to maintain the best sound quality, you will need to play this noise regularly as maintenance.If you notice a drop in sound quality, try playing this noise again. Repeat playback about 10 to 20 times is sufficient.
