The Audio Fool

Sampling a continuous waveform into discrete digital samples results in lost information. Discrete samples can only tell what the wave is doing at periodic instants in time, and not what's happening between them. The continuous sampled wave could be doing...

Aside from the distortion artifacts, one of the biggest problems that results from clipping is a loss of dynamic range. Remember that the dynamic range of a signal is effectively the difference between the maximum output level and the noise floor . When...

Below is an example of the Fletcher-Munson Equal Loudness Curve . It is one of the most recognized graphics in audio engineering. The horizontal axis is frequency of tones, and the vertical axis is actual sound pressure in dBSPL. Each point on a curve...
