transform time-domain signal to STFT-domain signal.\n- **_signal synthesis_**; transform STFT-domain signal to time-domain signal.\n\nCheck the [documentation](https://docs.zymon.org/STFT.jl/) for more insights.\n\n## Installation\n\nThe package is currently available in General, the default Julia package registry.\nTo install this package from General registry, use the following command in Julia REPL:\n```julia\n] add STFT\n```\nAlternatively, directly via repository:\n```julia\npkg\u003e add https://codeberg.org/zymon/STFT.jl\n```\n\n\n## Examples\n\nBelow you can find a few standalone examples with basic usage of the package.\n\n### Show spectrogram\n\n```julia\nusing STFT\nusing Plots\n\nx = randn(10000)  # Generate mock signal\nW = 64            # Window length\nw = ones(W)       # Rectangular analysis window\nH = 10            # Hop\nL = W - H         # Overlap\n\nX = stft(x, w, L)    # Analysis\ns = abs2.(X)         # Compute spectrogram\nheatmap(10log10.(s)) # Display spectrogram\n```\n\n### Analyse signal, modify, and synthesise\n```julia\nusing STFT\n\nx = randn(10000)   # Generate mock signal\nW = 64             # Window length\nw = ones(W)        # Rectangular analysis window\nH = 10             # Hop\nL = W - H          # Overlap\n\nX = stft(x, w, L)  # Analysis\nX = f(X)           # Modify STFT-domain signal\ny = istft(X, w, L) # Synthesis\n```\n\nAlternatively, instead of `using STFT`, you can `import STFT`,\nand use an alternative API, i.e., `analysis` and `synthesis`.\n\n```julia\nimport STFT\n\nx = randm(10000) # Generate mock signal\nW = 64           # Window length\nw = ones(W)      # Rectangular analysis window\nH = 10           # Hop\nL = W - H        # Overlap\n\nX = STFT.analysis(x, w, L)  # Analysis\nX = f(X)                    # Modify STFT-domain signal\ny = STFT.synthesis(X, w, L) # Synthesis\n```\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fs-zymon%2Fstft.jl","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fs-zymon%2Fstft.jl","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fs-zymon%2Fstft.jl/lists"}
