dsp Lab
Lab Assignment Last week, you were able to combine the two sounds (rain & bird) smoothly because both had the same sampling frequency: Fs=22,050 Hz. What happens if you want to mix samples recorded with a different sampling frequency? 1. List the properties of robot & cowbird audio files File name robot.mp3 cowbird.wav Compressed? Sampling frequency, Fs Number of channels, C Samples per channel, N Duration, 2. Answer Do both files have same sampling rate? What is the required operation to make both files having Fs = 22050Hz? 3. Create a mix of the two audio tracks as follows: bird then robot. The result should be of two channels. 4. Save the result of the mix in MP3/4 format. Then give the properties of the result audio file File name File size in KByte Compressed? Sampling frequency, FS Number of channels, C Samples per channel, N Duration, T In the Report 1. Required tables & answers of 2. The MATLAB script - well documented. 3. A plot of the mix with labels & title Upload The report (WORD) Only one member uploads the documents on the Blackboard, Lab Assignment Last week, you were able to combine the two sounds (rain & bird) smoothly because both had the same sampling frequency: Fs=22,050 Hz.
