2 cards from this section. Quick, good the night before a test.
What function is used to plot audio data in MATLAB?
Think about the creative capabilities of MATLAB graphs.
How do you get audio data from the audiorecorder object?
Recall the method to extract data after recording.
Which function is used to display data in a plot?
Recall the command that allows you to visualize.
True or False: The y-axis of an audio signal plot typically represents the amplitude.
Think about what height indicates in a sound wave.
Design a MATLAB function that records audio for a specified duration and visualizes it dynamically as it's being recorded.
Think about using 'pause()' to update the plot after each capture.
Compare the amplitude of different recorded signals through plotting. Write a script that records three different audio clips and plots them on the same graph.
Consider how overlaying allows for comparison between signals visually.
