Short-time Fourier transform

Stft Matlab Code

The short-time Fourier transform (STFT), or alternatively short-term Fourier transform, is a Fourier-related transform used to determine the sinusoidal frequency and phase content of local sections of a signal as it changes over time.

The following matlab project contains the source code and matlab examples used for stft.

Spectral smoothing in matlab

The following Matlab project contains the source code and Matlab examples used for spectral smoothing. This MATLAB exercise processes a designated frame of voiced speech from a user specified speech file, using a designated window and calculates the log magnitude spectrum of the STFT of the windowed frame of speech.

Inverse short time fourier transformation (istft) with matlab implementation

The following Matlab project contains the source code and Matlab examples used for inverse short time fourier transformation (istft) with matlab implementation. The present code is a Matlab function that provides an Inverse Short-Time Fourier Transformation (ISTFT) of a given spectrogram stft(f, t) with time across columns and frequency across rows.

Lpc varying l in matlab

The following Matlab project contains the source code and Matlab examples used for lpc varying l. This MATLAB exercise illustrates the matching behavior of the LPC polynomial log magnitude spectrum to the log magnitude spectrum of the STFT of the designated input frame of speech as a function of the frame size, Lm for a range of values of Lm; (e.

Short time fourier transform (stft) in matlab

The following Matlab project contains the source code and Matlab examples used for short time fourier transform (stft). %% function [t,frequency,Power_spectrum]=fft_s(y,windowlength) %% Inputs : % y: input raw signal % windowlength: window length to take fast fourier transform, it is a % factor of smapling frequency for example one can enter a window length % half of the sampling frequency by enteríng 0.
