Can you write the matlab code for the following task.

In this task, you will collect an audio signal of your own voice. You will then use this signal as

your data to analyse it in the time and frequency domains throughout all lab sessions.

In order to make the signal more realistic, you will record your voice in a noisy environment.

To that end, we have provided you with an audio file that you have to play in the background

using another device $($for example your mobile phone$).$ The Background noise file $$Noise$.$wav$$

can be downloaded from Canvas.

Note: Some built$-$in sound cards in laptops$/$PCs may not allow you to record your voice and

play audio at the same time. Hence, it is safer to use another device to play the background

noise while recording your voice.

To ensure the given noise is present in the background throughout the recording, you can try

the following:

$$ Start by setting the volume of the given sound to a moderate level before beginning the

recording.

$$ Start the recording and speak as you normally would while monitoring the audio levels

to ensure that your voice is audible and the background noise is not overpowering.

$$ If the volume of the background noise is too low, increase it until it is audible but not

overwhelming.

$$ If the volume of your voice is too low or the background noise is too high, adjust the

levels accordingly.

$$ Repeat this process until you achieve the desired balance of background noise and voice.

In this part, you will need to use MATLAB$$s audiorecorder and audiowrite commands.

Check the MATLAB documentation. There are plenty of examples of how to use

these commands.

For the purpose of this task, you may need to record up to ten $(10)$ seconds worth of data with

$3$

a sampling frequency of $48000$ samples per second, $8$ bits and $2$ channels. Each group needs

to collect one audio signal by saying the following phrase.

Phrase: $$If you can hear this, you are already experiencing Digital Signal Processing magic.

This is $..$

File Name: $$DSP$-.$wav$$

Note: You only need to collect one audio signal per group.

Note: Once you have finished recording your voice using the audiorecorder, use the

audioplayer or sound command in the CommandWindow to play back the recording and

examine its quality. Remember to specify the correct sampling frequency, as it may differ from

the default used by the audiorecorder function. To further verify that the recording is

functional, open the audio file in a separate media player $($outside of MATLAB$)$ and play it$.$

Once you are satisfied with the recording, save your file properly and make sure to keep this

file for the next tasks.

Remember that you will be using the same audio file throughout all lab

sessions.
