What is the effect of multiplying an audio signal by 0?
Think about what happens to sound when all its intensity is removed.
If volume = 1, what happens to the input signal?
Consider what multiplying by 1 does.
What is the main purpose of volume control?
Think about how we adjust volume on a speaker.
True or False: A volume factor greater than 1 will decrease the volume.
Consider what happens to audio when increased above the normal range.
Create a MATLAB function that accepts an audio input signal and a volume level, then outputs the adjusted audio signal.
Remember to define function inputs correctly.
Analyze the consequences of applying a volume level that exceeds the standard range (e.g., 1.5). Discuss potential steps to avoid distortion.
Think of ways to protect audio outputs.
