Method of adjusting an equalizer and electronic device performing the same
A method of adjusting an equalizer is disclosed. The method is applied to an electronic device for adjusting a plurality of gain values of the equalizer synchronously. The method of adjusting an equalizer of the present invention includes the steps of receiving an adjusting command; increasing or decreasing each of the gain values synchronously in an equimultiple way; storing adjusted gain values in a memory of the electronic device.
1. A method of adjusting an equalizer, applied to an electronic device, the electronic device comprising a screen and a memory, wherein the memory contains an original equalizer, the original equalizer being recorded with 1 st ˜N th gain values, wherein the 1 st ˜N th gain values are gain values at different frequencies, and 2≤N≤1,000, the method of adjusting an equalizer comprising the following steps:
providing a user interface displayed on the screen;
receiving an adjusting command imputted by a user operating the interface for modifying the original equalizer;
increasing or decreasing the 1 st ˜N th gain values synchronously in an equimultiple way to form a new equalizer according to the adjusting command, wherein the new equalizer is recorded with 1 st ˜N th new gain values; and
storing the new equalizer in the memory.
2. The method of adjusting an equalizer as claimed in claim 1 , wherein the 1 st ˜N th new gain values are M times the 1 st ˜N th gain values, respectively, and 1/30,000≤M≤3,000.
3. The method of adjusting an equalizer as claimed in claim 2 , further comprising the following step executed before the step of receiving the adjusting command: displaying the original equalizer via the screen; and the following step executed after the step of forming the new equalizer: displaying the new equalizer via the screen.
4. The method of adjusting an equalizer as claimed in claim 1 , wherein the user interface comprises an indicator bar and an adjustment point, the adjustment point being located on the indicator bar, wherein the adjusting command is inputted by the user moving the position of the adjustment point on the indicator bar.
5. The method of adjusting an equalizer as claimed in claim 1 , wherein the screen is a touch screen, and the user interface can be operated by means of a touch control operation, wherein the adjusting command is inputted by the user performing a dual touch gesture operation.
6. An electronic device, comprising:
a screen;
a memory, containing an original equalizer, the original equalizer being recorded with 1 st ˜N th gain values, wherein the 1 st ˜N th gain values are gain values at different frequencies, and 2≤N≤1,000; and
a processor, electrically connected to the screen and the memory, used for providing a user interface on the screen and receiving an adjusting command inputted by a user operating the interface for modifying the original equalizer, the processor further increasing or decreasing the 1 st ˜N th gain values synchronously in an equimultiple way to form a new equalizer according to the adjusting command and storing the new equalizer in the memory, wherein the new equalizer is recorded with 1 st ˜N th new gain values.
7. The electronic device as claimed in claim 6 , wherein the 1 st ˜N th new gain values are M times the 1 st ˜N th gain values, respectively, and 1/30,000≤M≤3,000.
8. The electronic device as claimed in claim 7 , wherein the processor is further used for displaying the original equalizer via the screen before receiving the adjusting command and displaying the new equalizer via the screen after forming the new equalizer.
9. The electronic device as claimed in claim 6 , wherein the user interface comprises an indicator bar and an adjustment point, the adjustment point being located on the indicator bar, wherein the adjusting command is inputted by the user moving the position of the adjustment point on the indicator bar.
10. The electronic device as claimed in claim 6 , wherein the screen is a touch screen, and the user interface can be operated by means of a touch control operation, wherein the adjusting command is inputted by the user performing a dual touch gesture operation.
