This application demonstrates how you can estimate the location of a signal that might exist in a larger (perhaps noisy) measurement. In this instance, we find the location of a small segment of audio in a larger audio file.
  • First, an audio file is first loaded, a small segment is extracted, and random Gaussian noise is added to both.
  • The cross-correlation of the full audio and the extract is computed, and the maximum lag computed.
The maximum lag is the index at which the extract is predicted to exist in the audio.
