Your mission will be to use MATLAB to perform both a narrow-band (larger frame length) and wide-band (smaller frame length) time-frequency analysis of a 15 second audio signal sampled at 8 kHz. The audio file is a 15 second segment of a telephone conversation from the Linguistic Data Consortium Call-Home database, which can be downloaded from blackboard. You need to partition the signal using two frame sizes, 8 and 32 milliseconds long (64 & 256 samples) with
