Logarithmic Audio Volume Control

[AlphaGeek1]

Is your feature request related to a problem? Please describe.
When adjusting the audio volume, most of the audible sound is heard at 75% to 100%. Ideally, some audio would be audible at 5% to 10%. This would be similar to an analog volume control which, electronically, are not linear because human aural perception is non-linear.

Describe the solution you'd like
Use a logarithmic ("the" logarithmic?) scale for volume adjustment so it is non-linear, similar to an 'audio taper' potentiometer.

Describe alternatives you've considered
None. The alternative would be to do nothing and leave the volume adjustment as it currently exists.

Additional
I am making an assumption that the volume control is setting the gain of the audio output using a linear scale based on personal experience with the software running on my personal Portapack. I may be wrong about this.

Do you think this is still an issue @AlphaGeek1 ? I feel my unit is quite audible on lower volumes with the current lineal scale

Thank you, yes. I usually don’t hear it until it’s up around 65 or 70. For comfortable listening, it’s about 80. If I hold the speaker right up to my ear, there is sound at about 25 where I can recognize words, but that’s FM broadcast pressed up against my ear. My thought is that this should be maybe at 15 or 20.. maybe 10 even. I am just wondering if any thought has been given to the fact that aural perception is logarhythmic rather than linear and to duplicate the ‘feel’ of a standard non-linear analog ‘volume’ control?
