Training Vivi
At the beginning, Vivi knows nothing about violin sounds – she needs a human to teach her. The human helps Vivi to learn by pointing out good and bad sounds. How important is training? Well, take a listen:
Number of audio snippets trained | Approximate time spent | Audio examples | |
|---|---|---|---|
32 | 5 minutes (basic training only) | separate scale mp3 | slurred scale mp3 |
94 | 15 minutes | separate scale mp3 | slurred scale mp3 |
203 | 40 minutes | separate scale mp3 | slurred scale mp3 |
All sound analysis and machine learning (training and classifying) is done with Marsyas.
User: basic training
Vivi asks you to classify short (approximately 0.5 seconds) bits of audio. These are created without any attacks, and are intended to test her "steady" sounds.
The sounds are classified as follows:
1. Much more force | mp3 | almost silent! |
2. More force | mp3 | |
3. Ok sound | mp3 | "ok" in comparison to the other sounds |
4. Less force | mp3 | |
5. Much less force | mp3 | not a violin? |
Automatic: calculating parameters
Once Vivi knows what a "good steady sound" should be, she tries to figure out how to generate those sounds.
- if she hears a bad sound, how much should she modify the bow force?
- how much bow force should she use before the bow is moving?
User: practice scales
Once Vivi has some basic knowledge and some bow forces, it’s time to help her practice scales!
Select a scale (and dynamic) to practice, then listen to Vivi’s performance. If any note sound questionable, you can examine that note and identify any areas in which Vivi’s judgement was incorrect.
