Hi, The amplitudes in the time domain and frequency domain are related, but they represent different aspects of the signal. In the time domain, the amplitude refers to the instantaneous value of the signal at a given time point, while in the frequency domain, the amplitude represents the strength or energy of different frequency components present in the signal.
The only error that you can expect in line 14 is if you have not misfollowed the syntax or any variable in line 14 is not defined earlier. Can you please mention exact line of error statement?

Thank you all, based on your responses, I have created a much detailed short playlist for audio signal processing in matlab, you can check that.
Bht ala brother it is working 100 percent
can you add for the effects like echo, reverb and equalization? thanks
hi, thanks for the great tutorial. i am wondering why is amplitude different in 2 charts in the end?

In what units is the amplitude?
good work
Thank you sir but the music is noisy
How to get bandwidth and spectogram of this signal
Bandwidth can be taken in terms of maximum frequency present in the signal.
My audio file is in aac format... How to convert that into wav
The command used in this code can read the files in all these formats .aifc .aiff .aif .au .flac .ogg .opus .wav .mp3 .m4a .mp4
I'm also getting error in line 2
GREAT WORK
Hie.. Line 2 r=audiorecorder(Fs, bits, channels) ; showing as error.. How to resolve?
channels=>Channels
Good work, man! Can u please provide the code here?
thanks
I am having error on line 14 and I can not identify the problem

Can you please mention exact line of error statement?
I m getting error in the second line....plzzz tell how to rectify it
error details?
@@matlabsignal249 Error using audiorecorder/set.DeviceID (line 334)
No audio input device found on this system. im getting this eeor in second line
Can I get a mathematical analysis for this audio processing
Thank you very much
Sir plzzzz help me to solve error in 2 nd line ( r= audiorecorder...)
Sir please 🥺
channels=>Channels
Y label in frequency is Power right ? not amplitude
Am i right ?
Please reply
right.
Hi. Sir a very nice demonstration.. sir can u guide me , in case i need to increase time to record my voice what I have to do for that ?
Please
duration = (seconds to record);
@@toheedh okay thank you sir
The music in background is really disturbing, i can't hear anything.
Are you able to understand the content presented?
@@matlabsignal249 I skipped this video because of the music, I completed my project with the help of another video.
@@IuthientinuvieI we are really sorry for this. We will surely update this in next few weeks.
The back ground music is really disturbing
scripte please
According our religouin we do no hear music
If you remove our bacground music of video it will easy for us thank you
I love you
the music is so annoying
thank you very much
