the words in this audio file is (wow sounding just gets easier and easier)
Part II Load the file sound editing.wav (uploaded to the course website on Bb) using the MATLAB command audioread. For this audio file, answer the following questions. (a) How many samples are in the sound file? What is the duration of each sound file? (b) What is the number of channels? (one or two? i.e., mano or stereo) (c) What is the recorded sampling rate, F., of the sound file in samples per seconds? (d) Listen to each file at different sampling rates (lower than, equal to, and above than f.). Comment on your results. (e) Listen to different parts of each file (for example, the first half of it, the last half of it, half of the file in the middle.). Comment on your results. (1) How many bits were used to represent each sample? (g) How many bits are needed to store the data assuming there is no data compression? How many bytes? (h) Suppose the sound editing wav file is stored with a 2.5:1 data compression ratio. How many bytes are needed to store the compressed data? (1) Consider the sound-editing wav file. Listen to the sound using the sound command. You will hear the speaker pronounce the expression "Wow!" Plot the entire sound file and you will see a group of waveforms. The first group is where the speaker is saying "Wow!" Zoom in on the plot and note the samples number at the start and at the end of the word "Wow!" Use these sample numbers to select the portion of the entire sound file where the speaker is pronouncing this word. Plot the word "Wowl" alone. Zoom in on the 'Wow!" sound and plot about 10 cycles of the "o sound in the word "Wow!"
