Gain and volume are two terms that are often used interchangeably in audio engineering. However, there is a subtle difference between the two.
Gain is the amount of amplification that is applied to an audio signal. When you increase the gain, you are making the signal louder. However, increasing the gain can also introduce distortion. Distortion is an unwanted change in the shape of the audio signal. It can make the sound harsh or muddy.
Volume is the perceived loudness of an audio signal. It is determined by a number of factors, including the gain, the impedance of the speakers, and the listening environment.
Feedback is a phenomenon that occurs when a portion of the output signal from an amplifier is fed back into the input of the amplifier. This can cause the signal to become amplified uncontrollably, leading to a loud, distorted sound.
Gain vs volume feedback
The main difference between gain and volume feedback is that gain is a property of the amplifier, while volume feedback is a property of the system. Gain is determined by the amplifier’s design, while volume feedback is determined by the way the amplifier is connected to the speakers and the listening environment.
Gain and volume feedback can be used to create different effects
Gain can be used to increase the loudness of an audio signal, while volume feedback can be used to create a variety of effects, such as reverb and delay. However, it is important to use caution when increasing the gain, as it can lead to distortion.
How to avoid feedback
There are a few things that you can do to avoid feedback:
- Make sure that the speakers are properly positioned. The speakers should be placed so that the sound waves from the speakers do not travel back to the amplifier.
- Use a noise gate. A noise gate is a device that can help to reduce feedback by cutting off the signal when the sound level is too low.
- Use a feedback suppressor. A feedback suppressor is a device that can help to reduce feedback by filtering out the frequencies that are most likely to cause feedback.
Gain and volume feedback are two important concepts in audio engineering. By understanding the difference between the two, you can use them to create the desired effects and avoid unwanted feedback.
