| Abstract |
Key finding in audio is based on the constant Q trans- form. A heuristics is suggested how to compress the con- stant Q transform into a 12-dimensional short-term pitch class profile. Short-term profiles are weighted by a co- sine window and summed up yielding long-term profiles. The latter are matched against averaged major and minor prototype profiles.erence key profiles.
This algorithm was placed second in the MIREX audio key finding competition. |
