First Claim
1. An information processing apparatus comprising:
- a parameter adjustment section to set, in accordance with a first parameter that is input indicating a variant factor for a playback speed of an audio signal, a second parameter and a third parameter, wherein each of the second parameter and the third parameter is configured to have variations comprising at least two regions of different ascending rates in accordance with the first parameter, the at least two regions separated by a predetermined threshold; and
a signal processing section to adjust, based on the second parameter and the third parameter and not based directly on the first parameter, at least one of the playback speed of the audio signal or a pitch of a sound of the audio signal,wherein the signal processing section adjusts, based on the second parameter, the playback speed of the audio signal when the variant factor for the playback speed is less than the predetermined threshold and adjusts, based on the second parameter and the third parameter, the playback speed of the audio signal and the pitch of the sound of the audio signal when the variant factor for the playback speed is above the predetermined threshold; and
a content management section to manage content including the audio signal, wherein the parameter adjustment section determines a fourth parameter that adjusts a data amount of the audio signal to be output from the content management section to the signal processing section in accordance with the first parameter that is input; and
wherein the parameter adjustment section reduces the fourth parameter to reduce the data amount of the content to be output from the content management section to the signal processing section when the first parameter is above the predetermined threshold.

Abstract
According to the present invention, a parameter adjustment section setting, in accordance with a first parameter indicating a variant factor for playback speed that is input, a second parameter and a third parameter, and a signal processing section adjusting at least one of playback speed and pitch of a sound of an audio signal based on the second parameter and the third parameter are provided, wherein the signal processing section adjusts the playback speed of the audio signal when the variant factor for playback speed that is input is less than a predetermined threshold and adjusts the playback speed and the pitch of a sound of the audio signal when the variant factor for playback speed that is input is above the predetermined threshold.
