The waveform in the sound will suddenly drop to a minimum of 5

The reason why the waveform in the sound suddenly drops to a minimum is as follows:

Step 3: Use the "regedit" command to enter the registry, press F3 to find the following items: LGSYZR, O2flash, Alga, iExp1ore, iExplora, ServiceA to delete all the searched value entries.

The same is to enter one and delete one) Step 4: Start - Run. Enter msconfig.

Banned alga and iexp1ore in the startup items! (Be sure to re-computer).

Step 5: Go to the System folder under Windows and delete the Alga file (if you still have one). Restart your computer,Open any kind of ** device,Start ****,Test whether the removal is successful,If you still encounter this problem, you need to re-operate the above operations,I carried out a total of 2 times to clean up these stubborn garbage。

If there are still problems after repeated above operations, don't scold me for lying, I am the result of the actual operation, the last trick must be known to everyone, format the system to reinstall.

Please ask if it has been resolved.

Your sound card isn't set up.

It's a decibel setting.

Oh tune in from the sound and audio devices in the control panel.

In the sound scheme, select Windows by default, and it should work!

Mathematical description of waves.

a*sin(f*t + fai)

The same tone means that the frequency f is the same.

The same loudness means that the amplitude a is the same.

But the FAI is a phase, which is not mentioned in the title, and is not necessarily the same.

It may be that you have fallen for an advertising Trojan, use antivirus software to check and kill it!

Just get an oscilloscope.

Faint, faint, faint, faint, sprinkle a vb

The frequency represents the tone, which is the dense representation of the tone at the intersection of the waveform diagram and the horizontal axis.

The amplitude represents loudness, which means that the greater the difference between the highest and lowest points in a period on the waveform graph, the higher the loudness.

There's a conversion device.

You can use an oscilloscope.
