- Rockin’ Patent: US Patent No. 7,974,838
- Filed: 3 March 2008
- In the name of: iZotope Inc
- Title: System And Method For Pitch Adjusting Vocals
- What’s claimed: ”A method performed by a processor, comprising: receiving a first audio signal; extracting a vocal signal from the first audio signal; receiving a second audio signal; determining a pitch for the second audio signal; determining a pitch for the extracted vocal signal by limiting a pitch detection range based on the determined pitch of the second audio signal; and adjusting the pitch of the second audio signal based on a difference between the determined pitch of the extracted vocal signal and the second audio signal.”
- Why this patent rocks: This patent describes a method that assists a singer and corrects their pitch and that is adapted for live performances, such as karaoke. Parts of the patent appear to be written in a tongue-in-cheek manner in stating ‘‘a singer’s enthusiasm may be far greater than their singing talent” and that off-key singing “can cause the performance to be much less enjoyable both for the singer and the audience”.
