Question
---------------limits the amplitude of audio signals that exceed a predetermined threshold
Select one:
- a. audio amplifiers
- b. Compressors
- c. filters
- d. audio mixers
Solution
The correct answer is b. Compressors.
Compressors are used in audio signal processing to reduce the dynamic range of the audio signal. They work by limiting the amplitude of audio signals that exceed a predetermined threshold. This helps to prevent distortion and clipping that can occur when the signal amplitude is too high.
Here are the steps of how a compressor works:
- The audio signal enters the compressor.
- The compressor checks if the amplitude of the audio signal exceeds the predetermined threshold.
- If the amplitude is above the threshold, the compressor reduces the amplitude to bring it back within the acceptable range.
- The compressed audio signal is then output from the compressor.
Audio amplifiers, filters, and audio mixers do not have the same function. Amplifiers increase the amplitude of audio signals, filters remove unwanted frequencies, and mixers combine multiple audio signals into one output.
