This equalizer app will not work if you start it while other equalizers are running,
so you need to start it according to the following procedure.
1. Completely stop both the GlycoX app and other equalizer apps.
1.1 For apps that cannot be terminated from notifications (some apps do not issue notifications)
Press and hold the icon to "force stop" on the "App information" screen.
2. Launch the GlycoX app.

===== For users with Android 10 or later =====
On Android 10 or later, you can enjoy music with the best sound by adjusting the Compressor.
The effector consists of Pre EQ --> Compressor --> Post EQ --> Limiter in this order.
1. How to easily increase the bass using Compressor (first try it at 62Hz, which is easy to hear)

- Lower the value of Pre Gain.
- Increase the value of Post Gain.
- Slightly lower the Ratio value.
- Increase Threshold a little.
(First of all, try moving the Seek Bar of these four parameters slowly left and right to feel the change in sound.)

2. The following is an example of how to adjust Post EQ at the end.

Step1. Set the Post EQ preset to FLAT.
Step2. Set all Compressor and Limiter presets to Default. (Don't set In Gain and Out Gain too high, just set them to about 0.
Step3. change Pre EQ, Pre Gain, and Post Gain to your favorite values for each frequency. Adjust the Ratio and Threshold as necessary.
Step4. increase the volume to the desired level with Out Gain. If necessary, adjust the In Gain.
Step5. Adjust Post EQ if necessary.

3. Operation mode
From v1.6.6, the following two operation modes are selectable.
- Standard
This mode was used until v1.5.6.
- Deep
This mode is for deep bass. It is effective to adjust the volume by lowering the In Gain and moderately increasing the Out Gain, Loudness, and Volume.
If you increase the In Gain too much, the bass effect will be reduced.
First, try adjusting the Pre Gain, Post Gain, and Pre EQ up or down at the default setting of 31Hz to feel the effect that could not be created with Standard.
(Note: The Bass Boost knob cannot be used in this mode.)

If you use Android 10 or later, you may not want to use Bass Boost as much as possible.
