Self-similarity matrix

Before use this feature, you need to import audio or movie or data file or compute audio descriptors.

1. Select Compute > Self-Similarity Matrix.
2. Select a file.
3. [Optional] Edit title of file.
4. If you select an audio file, change FFT parameters.
5. Edit definition: 1x = 2 000 pixels and 4x = 8 000 pixels.
6. Z-Score Normalization: (Only enabled on data file) This option makes the values of each data (eg audio feature) have zero-mean and unit-variance.
7. Select Compute.

You can use self-similarity matrix in temporal visualization or timeline.
