How to read and plot a wav file in both time an frequency domain (MATLAB)

u can use any wav file just bring it to the same directory as the script
and for begginer Dont Forget to Change the file name in the wavread function

[sharingmatlab]

Try to use # audioread # instead of using #wavreadt# OR show us your script to see the error

[daromc]

Which library are you using for the waveread(" ") command ?

[Easypeasy]

why the frequency signal does not appear, only a straight line

Hello Great video, just a few questions
1) In time domain plotting is time(sec) vs amplitude(dB). Is the unit right?
2) In frequency domain its G Vs F(Frequency)
What is G and Unit for both G and F.
Thanks in advance

Wonderful video explained coding. May I know, in which format the waveform 'test' is.?

kindly help me out..trying to read a wav file..it's very urgent

error is:

Error using wavread (line 167)
Unable to load a message catalog 'MATLAB:audiovideo:wavread'. Please check
the file location and format.

Error in x (line 1)
[f_audio, sideinfo]=wavread('Roland-JV-2080-101-Bass-C2.wav');

If you still get the wavread function undefined, it's because it's no longer used. Use audioread instead.

dear i get the program..as i m unable to do it ...plz help

Salam,

Can I ask what does this function do? I understand that you are plotting for f and G and inside the brackets represent the start and end point. However, why does the Nfft needs to be divided by 2? Is it to remove the mirror image?
plot (f(1:Nfft/2), G(1:Nfft/2))

Thank you!

HI THERE, AWESOME VIDEO ! can i ask you some question about plotting wav ?? is for an University Project and im looking for a bit o help :)

[ah]

Hi. Can you solve this problem
Write a Matlab code to get a .Wav file and process it as follows
i. Identify the sampling frequency (Fs) of the wav file, and plot the time domain signal.
ii. Change the sampling frequency of the original file as Fs/0.8 and plot the time domain signal and display the new sampling frequency value in console.
iii. Reverse the original signal and plot the time domain signal and hear the new sound.

i have a problem in matlab, this function has an error, i can't solve it
it's used to split the signal to frame in ordr to get mfccs

[MUSICISLIFESAM]

it's happening with all wav files ...using mattlab 2016a

[beccaroberts]

Hi, I tried mimicking what you did and it keeps telling me " undefined function or variable 'wavread' any suggestions?

[jonnathanlopes]

how can I create a multisignal with some independent signal frequency tone?

[EmreYavuzalp]

The thing is, I am using matlab for android and i want to make it to read a waw file. I tried everything, but it only gives errors. Help.

como plotar um histograma de um audio?

[ashishdev]

how to give the "file name" inside the wavread command.

[salsabilzaghdoudi]

How can I read multiple wav files one by one using a function ?

[touadamvinneet]

hey, please i need some link for audio coding using matlab
