Pitch shifting frequencies

摘要

System and methods for audio editing are provided. In one implementation, a computer-implemented method is provided. The computer-implemented method includes presenting a visual representation of digital audio data as a frequency spectrum including a first visual region corresponding to a first time period and a first frequency range in the digital audio data. A first user input identifies a second visual region within the first visual region and corresponding to a second time period and a second frequency range. A second user input specifies one or more frequency modifications to the second visual region. The second time period and the second frequency range corresponding to the second visual region are modified creating a modified second visual region. The modified second visual region is mixed into the first visual region creating edited digital audio data.

1. A computer-implemented method comprising:
presenting a visual representation of digital audio data as a frequency spectrum where the visual representation comprises a first visual region corresponding to a first time period and a first frequency range in the digital audio data; receiving a first input identifying a second visual region within the first visual region, the second visual region representing a pitch corresponding to a second time period and a second frequency range in the digital audio data, wherein the second time period is within the first time period and the second frequency range is within the first frequency range; presenting a graphic representation of the pitch represented in the second visual region, wherein one or more envelope control points are included on the pitch when the pitch varies over time within the second time period, the one or more envelopes outlining the pitch variance over time; receiving second input specifying one or more frequency modifications to the pitch represented in the second visual region of the digital audio data via user manipulation of at least one of the control points; based on the second input, modifying the digital audio data corresponding to the pitch represented in the second visual region to create a modified pitch in the second visual region; and mixing the modified digital audio data corresponding to the pitch in the second visual region into the digital audio data to create edited digital audio data.
