Conventional techniques for signal analysis and processing in the time-frequency domain are not well adapted to digital processing of music signals. This restricts the features and quality of applications. We present the current status of a research initiative on this problem. A novel family of wavelet-like bases allows a tiling of the time-frequency plane that is better adapted to digital music signals. This will allow performance enhancements in all kinds of digital audio applications.
