Title: Apparatus for converting pitch of encoded audio data
Inventor: MODEGI TOSHIO
IPC: G10L21/013
Filed: 2010-05-11
Abstract: PROBLEM TO BE SOLVED: To achieve natural audio reproduction without discomfort by performing pitch shifting in a simple manner on encoded audio data D expressing human voices.SOLUTION: Encoded audio data D which is a conversion target is input through a unit 110, and an offset value α indicating a pitch shift amount is input through a unit 120. In a unit 140, a weight function W(f) monotonically decreasing in accordance with increasing frequency f is stored. A unit 130 performs, on each code in the data D, a process of increasing or reducing the frequency f indicated by the code by a value according to α×W(f) and outputs a processed code as encoded audio data D. Since an actual pitch shift amount for each code is determined by multiplication by the weight function W(f), the pitch shift amount decreases with increasing pitch of the code. Thus, a pitch shift amount regarding a formant component is reduced, and the encoded audio data Dwhich allows natural audio reproduction is obtained in a simple manner.
