| # WaveMaster External Vibrato Evaluation Set |
|
|
| This dataset supports the external-corpus analysis in *Presence Is Not |
| Placement: Auditing What Vibrato Metrics Measure*. It contains unaccompanied |
| recordings of eight professional singers performing *Caro mio ben*. A full |
| release may additionally include the counterfactual renders used to test |
| whether a learned vibrato-presence judge responds to note-level vibrato |
| placement; `metadata.csv` is the authoritative list of included files. |
|
|
| ## Consent and identifiability |
|
|
| The singers participated through the Bach-Millennium Program. Each participant |
| gave written informed consent before recording, including consent to |
| redistribute their voice recording. A singing voice is inherently identifiable; |
| the singer IDs in this repository are pseudonyms, not a claim that the audio is |
| anonymous. Names, contact information, consent forms, and unrelated recordings |
| are not included. |
|
|
| The recordings were used only as an external evaluation set. They were not used |
| to train WaveMaster or any of its five fold-specific classifiers. |
|
|
| ## Contents |
|
|
| Every release contains the eight original recordings: |
|
|
| ```text |
| audio/ |
| original/singer_01.mp3 ... singer_08.mp3 |
| metadata.csv |
| ``` |
|
|
| If redistribution of modified derivatives is also authorized, the builder can |
| add the exact audit renders: |
|
|
| ```text |
| audio/ |
| identity/singer_01.wav ... singer_08.wav |
| shuffle/singer_01.wav ... singer_08.wav |
| jitter/singer_01.wav ... singer_08.wav |
| depth_0p5/singer_01.wav ... singer_08.wav |
| depth_2/singer_01.wav ... singer_08.wav |
| constant_130/singer_01.wav ... singer_08.wav |
| constant_420/singer_01.wav ... singer_08.wav |
| ``` |
|
|
| `original` contains the contributed performances. When included, `identity` is a WORLD |
| round-trip with no intended pitch change. `shuffle` reassigns the measured |
| vibrato depths among notes. `jitter` applies a similarly sized random note-level |
| perturbation. `depth_0p5` and `depth_2` globally halve or double vibrato depth. |
| `constant_130` and `constant_420` assign the same target depth, in cents, to |
| every measured note. |
|
|
| `metadata.csv` records the pseudonymous singer ID, condition, manipulation |
| amount, source-versus-derived status, duration, sample rate, channel count, |
| codec, file size, and SHA-256 checksum. |
|
|
| Only the *Caro mio ben* files used in the paper are included. The singers also |
| recorded scales, passaggio exercises, and other songs; those recordings are not |
| part of this research release. |
|
|
| ## Dataset creation |
|
|
| The original recordings were made in a room and with equipment different from |
| VocalSet. When included, the counterfactual files were generated with the |
| paper's public analysis code. Fundamental frequency was decomposed into a slow trend, a |
| 3--9 Hz vibrato component, and a residual. Only the vibrato component was |
| scaled or reassigned, after which WORLD resynthesized the audio while retaining |
| the analyzed spectral envelope and aperiodicity parameters. |
|
|
| ## Intended use and limitations |
|
|
| The intended use is reproduction and extension of research on vibrato |
| measurement, expressive-placement evaluation, and singing synthesis. The set is |
| small: eight singers, one Western classical song, one take per singer, and one |
| recording context. It should not be treated as representative of singers, |
| singing traditions, or listeners generally. Counterfactual files contain WORLD |
| resynthesis artifacts and are controlled stimuli, not natural performances. |
|
|
| Do not infer identity or sensitive traits from the recordings. Do not use the |
| recordings to impersonate a participant. See [TERMS.md](TERMS.md) for the |
| applicable release terms. |
