Description: This code implements automatic gain control for audio signals, which attempts to apply a smoothly-varying gain to an audio waveform in order to keep its energy close to some target level. This version also tries to balance the energy in individual frequency bands. It works by taking the short-time Fourier transform of the signal, smoothing that energy using time and frequency scales specified as arguments, then dividing out that scaled energy Platform: |

Description: STFT和ST变换的基本函数,和一个stft的一个例程-This code computes the Stockwell transform (S-Transform) of a one dimensional series without for loop, thereby making it computationally fast and simple. S-Transform was proposed in 1996. A nice tutorial on S-Transform can be found here:
djj.ee.ntu.edu.tw/S_Transform.pdf?
File Information Description
The present code is a Matlab function that provides a Short-Time Fourier Transformation (STFT) of a given signal x(n). The algorithm is similar to that of Matlab command “spectrogram”. The result is:
1) stft- a matrix with complex stft coefficients with time across columns and frequency across rows
2) f- frequency vector
3) t- time vector.
swt Discrete stationary wavelet transform 1-D.
swt performs a multilevel 1-D stationary wavelet decomposition
using either a specific orthogonal wavelet ( wname see
WFILTERS for more information) or specific orthogonal wavelet
decomposition filters. Platform: |

Description: 目前的代码是一个matlab函数,它提供给定信号x[n]的短时傅立叶变换(stft)。该函数是matlab命令“光谱图”的一个替代项。功能输出为:
1)一个具有复杂stft系数的矩阵,该矩阵具有跨列时间和跨行频率;
2)频率矢量;
3)时间矢量。
为了阐明函数的用法,给出了一个示例。为了方便起见,输入和输出参数在函数的开头给出。(The present code is a Matlab function that provides a Short-Time Fourier Transform (STFT) of a given signal x[n]. The function is an alternative of the Matlab command spectrogram The output of the function is
1) a matrix with the complex STFT coefficients with time across the columns and frequency across the rows;
2) a frequency vector;
3) a time vector.
An example is given in order to clarify the usage of the function. For convenience, the input and output arguments are given in the beginning of the function.) Platform: |
