Part 1. Understanding the Audio Speeding Process

How Audio Speed Affects Pitch and Quality

Audio speed affects the pitch of files that are adjusted by having their pitch made higher or lower depending on the speed modification that has been applied. Increasing the audio speed will result in a higher pitch, while lowering the audio speed will result in a lower pitch. When it comes to quality, expect slight quality degradation when adding audio adjustments such as speed editing.

Difference Between Changing Playback Speed and Altering Audio Files

Changing playback speed will result in the music playing faster or slower depending on the adjustment that has been applied. The effect will become similar to a video that is being played in fast-forward. On the other hand, altering audio files refers to all kinds of adjustments that can be done in an audio, such as compression, cutting, volume adjustment, and playback speed changing. In short, changing playback speed is a type of audio-altering option.

Factors Affecting Audio Quality After Speed Adjustments

Since applying speed adjustment is a form of audio altering, it is natural for the audio file that is being edited to have its audio quality change. The most common result of this is the audio quality being lower than pre-processing. Keep this factor in mind when playing around with audio adjustments.
