Doing a fft on a audio file - MATLAB & Simulink
https://www.mathworks.com/matlabcentral/answers/306187-doing-a-fft-on-a-audio-file
2016-10-7 · Hello, dear community! Really would appreciate a solution to my problem. i want to do a fft on a audio file, which duration last about 10 seconds. My goal is to make a fft on each seconds (1-10) and make it visible in a frequency- and time domain. So i can see, what happened in the last seconds and see the changes.

2020-11-13 · Suppose you are to compress by 74%. Then fft () and extract and retain (100-74) = 26% of the fft coefficients. You will have removed 74% of the information, so that will be compression. To reconstruct the signal, know the original number of samples, and create a vector of zeros that long, and write the saved coefficients into that vector in the ...

2015-9-4 · Due to the increasing demand for better speech algorithms, several standards were developed, including MPEG, MP3, etc. Data compression using transformations such as the DCT and the DFT are the basis for many coding standards such as JPEG, MP3 and AC-3. In this project FFT (IFFT) is used for the compression (decompression) of a speech signal.

2018-6-28 · Audio/video compression frees up space substantially, which can then be utilised for other purposes. This article describes some important audio compression techniques. An audio signal sample is taken and analysed using MATLAB for frequency and amplitude. Haar and Daubenches algorithms are applied on the speech signal and the audio is compressed.
