Question: Download the audio file "Test Audio" from this folder. Use Matlab programming to answer the questions. Submit the codes along with any graphs and results. 1. (20 points) Write the information about the audio file. a. Sampling frequency b. Time duration c. Number of channels d. Bits per sample e. Size of the file f. Compression status 2. (20 points) Calculate the following. a. Total number of samples b. Total number of bits c. File size 3. (30 points) Create new audios from the given file using different sampling frequencies. Listen to the new audios and write your observations. Submit the audio files also. a. 80% of the original sampling frequency b. 60% of the original sampling frequency 4. (30 points) Create new audios from the given file using amplification factors. Listen to the new audios and write your observations. Submit the audio files also. a. double the amplitude (e.g. yl=y2;; b. five times the amplitude (e.g. y2=y5;)
