# STFT.jl

`STFT.jl` is a Julia package implementing Short-Time Fourier Transform (STFT) routines.
|
|
It provides signal analysis (time-domain signal to STFT-domain signal; stft)
|
|
and signal synthesis (STFT-domain siganl to time-domain signal; istft).
|
|
|
|
|
|
# Examples
|
|
|
|
```julia
|
|
import STFT
|
|
|
|
x = rand(10000) # Generate mock signal
|
|
W = 64 # Window length
|
|
w = ones(W) # Rectangular analysis window
|
|
H = 10 # Hop
|
|
L = W - H # Overlap
|
|
|
|
X = STFT.analysis(x, w, L) # Analysis
|
|
|
|
# Compute spectogram of the signal
|
|
spectogram = abs2.(X)
|
|
|
|
# X = f(X) # Modify STFT-domain signal
|
|
|
|
# Reconsturction
|
|
xr = STFT.synthesis(X, w, L) # Synthesis
|
|
```
