What does audio taper mean?
Glossary Term: Audio-Taper When used in an amplifier circuit, the output varies slowly as the pot is operated at the low end and varies more and more rapidly as the pot is operated toward the high end. This is also called an audio taper because it is most commonly used for audio volume controls.
Is audio taper same as log?
Very simply, with a linear taper, if you turn the pot halfway, the resistance measured on each side will be equal. With logarithmic (aka “audio”) taper, that is not true; the resistance follows a logarithmic progression. Log taper is used because it gives a more natural progression when used for volume control.
Is Audio a taper log?
To compensate for the ears logarithmic behavior, audio taper pots were developed. While it is called logarithmic, it is actually an exponential curve (the opposite of the logarithmic behavior of the human ear).
What’s the difference between audio taper and linear taper?
The vast majority of pot manufacturers agree that the “A250k” is the audio taper and the “B250k” is the linear taper. It certainly is that way with CTS, Bourns, & Alpha pots.
Which is better an audio taper pot or a tone control?
In terms of an audio taper pot on the tone control, it works the same way… nothing until it gets to about “3” or so and then a LOT of warmth. There are science people that will tell you that audio taper pots are better for volume due to the way that the human ear hears.
What’s the difference between linear and linear taper pots?
When you dial up a linear pot, the signal increases in a very predictable, linear way… At “1”, it gives you 10% of the available signal. At “4”, it gives you 40% of the available signal and at “9”, it gives you 90% of the available signal. An audio taper pot increases the signal logarithmic manner.
How is a potentiometer related to a linear taper?
Potentiometer taper is the relationship between the position and resistance of the pot. In a linear taper the relative position is equal to the resistance ratio. For example, rotating the potentiometer to 50% will cause the pot to function at 50% of the maximum resistance.
