Onset Detection

To detect the onset of musical notes or events, use the following steps:

  1. Create an instance of the AubioOnset class
  2. Provide audio input to the AubioOnset instance
  3. Set the desired onset detection parameters (e.g., threshold, silence threshold)
  4. Call the process method to process the audio and obtain onset information
  5. Retrieve the detected onsets using the getOnsets method

Pitch Detection

To detect the pitch (frequency) of musical notes, use the following steps:

  1. Create an instance of the AubioPitch class
  2. Provide audio input to the AubioPitch instance
  3. Set the desired pitch detection parameters (e.g., algorithm, tolerance)
  4. Call the process method to process the audio and obtain pitch information
  5. Retrieve the detected pitch using the getPitch method

Beat Tracking

To track the beat and tempo of music, use the following steps:

  1. Create an instance of the AubioBeat class
  2. Provide audio input to the AubioBeat instance
  3. Set the desired beat tracking parameters (e.g., minimum and maximum BPM)
  4. Call the process method to process the audio and obtain beat information
  5. Retrieve the detected beat positions using the getBeat method
