good work

GREAT WORK

[@NeoStudy7]

thanks

[@yuantian1866]

hi, thanks for the great tutorial. i am wondering why is amplitude different in 2 charts in the end?

[@shivendragangwar1253]

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.

Thank you very much

[@thrishaallampally2826]

Can I get a mathematical analysis for this audio processing

[@saitejakatta664]

Good work, man! Can u please provide the code here?

[@eqtidarma4726]

Thank you sir but the music is noisy

[@mayarabdelfattah3513]

How to get bandwidth and spectogram of this signal

[@matlabsignal249]

Bandwidth can be taken in terms of maximum frequency present in the signal.

[@ptrk2032]

In what units is the amplitude?

[@merryarshed3288]

I'm also getting error in line 2

[@vaishu5301]

My audio file is in aac format... How to convert that into wav

[@matlabsignal249]

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

[@StoriesoftheSoul1018]

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

[@toheedh]

duration = (seconds to record);

[@StoriesoftheSoul1018]

@@toheedh okay thank you sir

[@sippyralinbenitas9413]

Hie.. Line 2 r=audiorecorder(Fs, bits, channels) ; showing as error.. How to resolve?

[@MiltonKanje-dc3uj]

I am having error on line 14 and I can not identify the problem

[@matlabsignal249]

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?

[@sukshithshetty8349]

Y label in frequency is Power right ? not amplitude Am i right ? Please reply

[@matlabsignal249]

right.

[@lostangel4299]

I m getting error in the second line....plzzz tell how to rectify it

[@matlabsignal249]

error details?

[@_PranaliMane]

Sir plzzzz help me to solve error in 2 nd line ( r= audiorecorder...)

The back ground music is really disturbing

[@shahsaud9644]

According our religouin we do no hear music If you remove our bacground music of video it will easy for us thank you

[@IuthientinuvieI]

The music in background is really disturbing, i can't hear anything.

[@matlabsignal249]

Are you able to understand the content presented?

[@IuthientinuvieI]

@@matlabsignal249 I skipped this video because of the music, I completed my project with the help of another video.

[@matlabsignal249]

@@IuthientinuvieI we are really sorry for this. We will surely update this in next few weeks.

the music is so annoying
