Reading, manipulating and analyzing audio files (.wav) in MATLAB
Three audio signals are provided to you (bass.wav, drums.wav and guitar.wav). Extract a segment from each audio signals (from 10th second to 20th second of each audio signal). Listen to each signal. After step 2, combine all the three signals and listen to the final audio signal. Increase the bass part of the signal (obtained in step 3) to 3 times. Listen to the audio and see the difference. Gradually increase the amplitude of the drums in the audio signal obtained in step 3. Listen to the audio obtained. Create a stereo audio signal by combining all the three audio signals given in step 1.
Five speech signals are provided to you (one.wav, two.wav, three.wav, four.wav and five.wav). Recognize the given test/unknown speech signal (test.wav and test2.wav) using correlation concept.
