This repository contains materials for performing modal synthesis of waterbottles. Currently we have measurements for two waterbottles, a 32 oz. Wide Mouth HydroFlask, and a DAFx 2019 bottle. We measure with differing amounts of water and stickers on the bottles.
The organization of the repository is as follows:
./ : Python scripts for analyzing waterbottle recordings
Audio/ : Audio examples (measured and synthesized)
BespokeWaterbottleSynth/ : A bespoke waterbottle synthesizer plugin
Bin/ : Builds of the both synthesizer plugins
Figures/ : Plots of waterbottle modal analysis
Impact_Wavs/ : Recordings of waterbottle impact drivers
Paper/ : DAFx paper on waterbottle synthesis
WaterbottleSynth/ : A HydroFlask waterbottle synthesizer plugin
Waterbottles-web/ : A web app for analyzing waterbottle recordings
This repository also comprises supplementary material for the DAFx 2020 paper "Water Bottle Synthesis with Modal Signal Processing", by Jatin Chowdhury, Elliot Canfield-Dafilou, and Mark Rau.

The plugins in this repository are built using the
JUCE framework, specifically JUCE
v5.4.4. Both plugins can be played through their on-screen keyboards,
as well as through a connected MIDI keyboard. The plugins are currently
available in the following formats: VST, VST3, AU, Standalone. To download
the plugins see the Bin/ folder.
The WaterbottleSynth is a real-time modal synthesizer model of a 32 Oz. Wide-Mouth HydroFlask. The amount of water inside the bottle, as well as the item used to strike the bottle are parameters of the plugin that change the waterbottle timbre. The swinging vibrato of the waterbottle can be controlled by the "Swing Damp" and "Swing Modes" knobs. Stickers can also be attached to the bottle by clicking and dragging on the screen, as well as removed from the bottle by clicking on the surface of the sticker. The stickers alter the damping of the waterbottle modes.
The BespokeWaterBottleSynth is a real-time synthesizer that can be used
to model any waterbottle. To load your own waterbottle, click the "reload"
button, and select a waterbottle config file (*.waterbottle) from your
computer. As an example, we provide a waterbottle config for the DAFx 2019
waterbottle. To create a *.waterbottle file from your own waterbottle
recording, visit our web app.
All other parameters are the same as for the WaterbottleSynth above.
