How to find audio samples from MFCC?

I had calculated MFCC of audio frames. I have to reconctruct audio samples from MFCC.

Please provide guidance.

Hi Shilpa,

As per my understanding of the question, you can reconstruct audio samples from MFCC in MATLAB using the following steps:

1. Load the audio file into MATLAB.
2. Extract the MFCC coefficients from the audio file.
3. Use the “idct()” function to convert the MFCC coefficients back to audio samples.
4. Play the audio samples.

Thanks

Ok ma'am. I will use idct() function. Thank you so much ma'am.

I have used idct function to reconstruct audio samples. when audio signal is played, it is random signal. But i have provided input signal as a mfccs of 'Digit-1'. wrong audio samples are reconstructed.

please provide guidance.
