Matlab GUI to demo the original REPET.
Functionalities:
- Open Mixture
- Play/Stop Mixture
- Select/Drag
- Zoom
- Pan
- REPET
- Save Background
- Play/Stop Background
- Save foreground
- Play/Stop Foreground
- Select a WAVE or MP3 to open; the mixture can be mono or stereo.
- Display the mixture signal and the mixture spectrogram; the x-axis limits of the mixture signal axes and the mixture spectrogram axes will be synchronized (and will stay synchronized if a zoom or pan is applied on any of the axes, including the background and foreground signal and spectrogram axes).
- Play the mixture if the playback is not in progress; stop the mixture if the playback is in progress; a playback line will be displayed as the playback is in progress.
- If there is no selection line or region, the mixture will be played from the start to the end; if there is a selection line, the mixture will be played from the selection line to the end of the mixture; if there is a selection region, the mixture will be played from the start to the end of the selection region.
- If a left mouse click is done on any signal axes (mixture, background, or foreground signal axes), a selection line is created; the audio will be played from the selection line to the end of the audio.
- If a left mouse click and drag is done on any signal axes or on a selection line, a selection region is created; the audio will be played from the start to the end of the selection region and REPET will be applied only to the selection region.
- If a left mouse click and drag is done on the left or right boundary of a selection region, the selection region is resized.
- If a right mouse click is done on any signal axes, any selection line or region is removed.
-
Turn zooming on or off or magnify by factor (see https://mathworks.com/help/matlab/ref/zoom.html)
-
If used on a signal axes, zoom horizontally only; the x-axis limits of all the signal axes and all the spectrogram axes will stay synchronized.
-
Pan view of graph interactively (see https://www.mathworks.com/help/matlab/ref/pan.html)
-
If used on a signal axes, pan horizontally only; the x-axis limits of all the signal axes and all the spectrogram axes will stay synchronized.
- Apply the original REPET to the mixture signal or the selected region of the mixture signal if any.
- Compute the beat spectrum and estimate the repeating period, and display them; the repeating period period can be changed by dragging the beat line or by selecting on the beat spectrum axes, which will update the background and foreground estimates.
- Derive the background and foreground estimates from the mixture signal or the selected region of the mixture signal, and display their signals and spectrograms; the select, zoom, and pan tools will work the same way on the background and foreground signal and spectrogram axes.
- Save the background estimate as a WAVE file; the default name is "background_file.wav."
- Play or stop the background estimate (see Play/Stop Mixture).
- Save the foreground estimate (see Save Background).
- Play or stop the foreground estimate (see Play/Stop Mixture).

- Open the mixture (see Open Mixture).
- Play or stop the mixture (see Play/Stop Mixture).
- select or drag on a signal or spectogram axes (see Select/Drag).
- Zoom on a signal or spectogram axes (see Zoom).
- Pan on a signal or spectogram axes (see Pan).
- Apply REPET-SIM to the mixture signal or the selected region of the mixture signal if any.
- Compute the self-similarity matrix and display it, and estimate the repeating elements.
- Derive the background and foreground estimates from the mixture signal or the selected region of the mixture signal, and display their signals and spectrograms; the select, zoom, and pan tools will work the same way on the background and foreground signal and spectrogram axes.
- Save the background estimate (see Save Background).
- Play or stop the background estimate (see Play/Stop Background).
- Save the foreground estimate (see Save Foreground).
- Play or stop the foreground estimate (see Play/Stop Foreground).
