Meeting at King's College¶

Mathieu Barthet, Daniel Leech-Wilkinson, Dan Tidhar

New tutorials for Sonic Visualiser¶

Online video tutorials¶

- covering basic features:
- how to load a sound
- how to install a Vamp plugin
...

- video tutorials targeting the analysis of various musical variables (timing, pitch, timbre, etc.)

- video tutorials associated with the examples from "A musicologist's guide to Sonic Visualiser" by Nicholas Cook and Daniel Leech-Wilkinson

Tutorials linked to Pitch analysis:

• How to obtain a graphic melodic shape:

- Use the MIDI tool to mark the notes
- Copy the layer in a time layer

This makes easier the analysis of the relationships of the melodic contour with tempo curves.

Example that can be used:

Strong correlation between melody & tempo contours in the performacne of the Chopin berçeuse by Cortot.

Tutorials linked to Dynamics analysis:

• How to change the resolution of the energy curve:

- Use the Power curve Mazurka plugin
- Change the settings to change the smoothing factor

• Ideas for Sonic Visualiser improvements **

- Layer display:

It would be useful to be able to change the dynamic range of layer curves (vertical compression) and their relative positions to facilitate their comparisons.

This may be a way to adapt the display to the way we perceive different audio streams.

Example: Cortot - 8th prelude Chopin

- Computation of correlation coefficients between different curves (e.g. Pearson r between the melodic contour curve and the tempo curve).

• Ideas for new Vamp plugins **

- Vamp plugin to characterise the harmonic complexity of a piece

Key recognition gives a bit of information about harmonic complexity.

Harmonic complexity may be characterised by a post-processing of the chromagram.

- Vamp plugin to measure the dissonance

- Vamp plugin to measure the roughness

• Feedback on Sonic Visualiser Library Edition **

Dan L-W. and Dan T. agreed to give some feedback on the new features from the Library Edition (e.g. templates).

• Issue: order of the layer tabs **

Each time a session file is opened, the tabs of the layers appear in different orders, making it impossible to refer to a specific tab number in tutorials or lectures.
