For this exercise, you need to access some wav files. If you have your own inventory of wav tiles. you are welcome to use them here. (Make sure the file is long enough for the exercise; see below) It not. a tile called eco2026Lab01voice.wav can be downloaded from t-square for your use Liam to use the audioread command to read the data into an array, say xx. You can find out how long the signal is in seconds by reading the length of the array via length (xx) which gives you the loud number of dimples and then divide it by f s. the sampling rate in samples per second. Then, plot the sound wave xx from 0.25 to t = 0.5 it 0.5 You need to know how to translate time into the index of the array; an example has already been shown above Show the plotted result to the instructor For this exercise, you need to access some wav files.
