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.
