Hello Mike, > Every real volume control you have used stretches the top part of its range > across the bulk of the physical travel. It's called the audio taper A typical audio taper is simply a logarithmic potentiometer, right? So Windows volume level sliders should behave like them. MS describes them as the following: "For a particular travel distance, the amount by which the perceived loudness increases or decreases is approximately the same regardless of whether the slider movement occurs in the lower, upper, or middle portion of the slider's range of movement. Perceived loudness varies approximately linearly with the logarithm of the audio signal power". If I specify -6..6 dB for the range, SndVol32 sets the "0 dB" position exactly to the middle. For -12..12 dB, it sets the "0 dB" to about 25% and so on. The wider is the absolute range, the less is the attenuation range, and the more is the boost range. What is a reason for it? Or SndVol32 still uses a linear scale instead of a logarithmic one? > You rarely want precision control below -20dB, whereas above that > the ear is sensitive to less than a dB of change and its where you > want fine control I need a precise control for the recording purpose, not for hearing only.
