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
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
