Abstract

Time Scale Modification (TSM) is a principle that is used to modify the time axis or time resolution. This concept can be used in Audio processing as well as Image processing. In this research work, TSM concept is used to perform Time Stretching of an audio signal. In this concept , the speed of the audio playback is changed without affecting audio signal's pitch. The time stretching concept has been used extensively in different application, such as in post production for effects, during music mixing. This is also used in the application to capture or play back a slow motion video. If we look at the current scenario, Time Stretching is extensively used in the field of entertainment, and creative arts. My paper talks about using this Time Stretching in the Automobile Industry. Now a days we have different types of FM stations (Digital and Analog). There is one particular scenario which I have considered as the Problem statement.
