Abstract
Methods to automatically correct timing of recorded audio in GUI are summarized here. One or more controls to adjust resolution of timing and degree of correction for the audio are displayed. The resolution of timing relates to beats on a grid and is affected by the degree of correction. The degree of correction is mapped to a time interval at each beat along the grid. Next, a user manipulation of one or more controls selecting a resolution and a degree of correction is received. Correction of timing is performed according to the selected resolution and degree of correction. Correcting of timing may include aligning a transient of the audio to the beat by compressing or stretching a portion of the audio. Compressing or stretching the portion of the audio depends on a length of the portion relative to a distance between adjacent beats.
