Frequency Dependent Time-Scale Modification
Abstract
Current Time-Scale Modification algorithms scale all frequencies by the same amount. This paper presents an efficient method and implementation for time scaling of arbitrary frequency regions, called Frequency Dependent Time-Scale Modification. This is achieved by creating a composite frequency spectrum frame before using traditional frequency domain time-scaling methods. Testing was undertaken with results presented from varied processing of 3 files. Links to and description of a MATLAB implementation are provided. Availability: A MATLAB software implementation can be found on Github at github.com/zygurt/TSM.
