Alap kéne legyen. Originally shared by Aladin Q SeekBar with a logarithmic scale on Android. A linear volume slider do not match human perception of sound intensity (Psychoacoustics). Consequently, using a SeekBar to properly control a volume in your application requires little extra code.  A SeekBar ranging from 1 to 100 returns value from 1 to 100, linearly ( y = x ): 1 -- 25 -- 50 -- 75 --> 100 A logarithmic SeekBar ranging from 1 to 100 returns value from 0 to 100: 0 --  4 -- 20 -- 52 --> 100 This trivial formula y = (x²/200)*log(x) in the OnSeekBarChangeListener listener will allow us to change the default linear SeekBar into a logarithmic one. --- @Override public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {     int x = progress;     int y = (int) (((x*x)/200)*Math.log10(x));     // Use the value "y" to control a volume level } #Android   #AndroidDev   #SeekBar  Audioid
