Audio Amplitude Distortion

June 3rd Fact-of-the-Day

Audio frequency response gets lots of attention, but amplitude distortion tends to degrade audio quality more than limited frequency response. The two are different and there is no basis for direct comparison. However, practical experiments have repeatedly found that listeners prefer limited frequency response where amplitude distortion is high and wide frequency response where amplitude distortion is low. Therefore, unless amplitude distortion is low, wide frequency response not only provides no benefit, it actually tends to be undesirable. The path to good-sounding audio is to first minimize amplitude distortion and then widen the bandwidth. ©2005 Martek International All rights reserved.
