If audio samples are read out faster than they are written the delay decreases. Using variable speed reading prevents pops, clicks, gaps, distortion and noise from being introduced into the audio, but does create unwanted and annoying pitch errors. For example, reading faster than writing causes the audio pitch to increase and reading slower than writing causes the pitch to decrease.
If audio samples are read out at a faster rate than they are written, the delay diminishes. Utilizing adjustable reading speeds avoids pops, clicks, gaps, distortions, and noises being introduced into the audio; however, it generates unwanted and bothersome pitch discrepancies. For instance, reading faster than writing results in an elevated audio pitch, while reading slower than writing leads to a lowered pitch.
