[Solved]Mission Use Matlab Perform Narrow Band Larger Frame Length Wide Band Smaller Frame Length Q37068841
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 50% overlap, ie, the first half of the samples in the next frame will overlap the last half of the samples in the current frame. You should also use a Hanning window to tapper each frame and take 512-point FFTs. You will need to take the log-magnitude of both sets of frames and create two plots with frequency on the y-axis and time on the x-axis. Note: you should only display the first 257 frequency samples of the FFTs, since the remaining are redundant. Be sure to label vour figures and turn in vour code Show transcribed image text 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.
