Hangmagasságkorrekció

Hangmagasságkorrekció, commonly referred to as pitch correction, is an audio processing technique used to alter the perceived pitch of a sound. This can be done to correct inaccuracies in vocal performances or instrumental recordings, or as a creative effect. The most well-known application of hangmagasságkorrekció is in vocal tuning, where it can fix slightly off-key notes, making a singer sound more in tune.

The process typically involves analyzing the incoming audio signal to identify its fundamental frequency. Algorithms then determine the closest desired pitch, often based on a predefined scale or user-specified target notes. Once identified, the algorithm adjusts the pitch of the original sound to match the target. This adjustment can be subtle, creating a natural-sounding correction, or it can be exaggerated for a noticeable, robotic effect, as popularized by artists like Cher and in various electronic music genres.

Modern hangmagasságkorrekció software offers a high degree of control. Users can often set the speed of correction, the type of scale to adhere to, and even the character of the correction. While primarily used for vocals, pitch correction can also be applied to instruments. However, its application to instruments can sometimes be more challenging due to the complexity of their harmonic content and the potential for unnatural-sounding artifacts if not applied carefully. The goal of hangmagasságkorrekció is to enhance or creatively manipulate audio, making it a ubiquitous tool in modern music production and audio editing.
