| # Harmonic Frontier Audio – Modal Phonation (Preview, v0.9) |
|
|
| **A high-fidelity human vocal dataset designed for AI training, speech research, and expressive voice modeling.** |
|
|
| **Modal Phonation (Preview)**, created by **Harmonic Frontier Audio**, provides a compact reference set demonstrating the quality, formatting, and metadata conventions used in the Harmonic Frontier Audio *Human Vocality Primitives* series. |
|
|
| --- |
|
|
| ## 🔎 Summary |
|
|
| This dataset provides high-quality, rights-cleared recordings of **neutral modal phonation** — steady, naturally voiced vocal behaviors captured across systematic variations in register, vowel configuration, amplitude, and onset character. |
|
|
| The full dataset encompasses: |
| - sustained modal vowels across low, mid, and high register zones |
| - open, mid-front, high-front, mid-back rounded, and high-back rounded vowel configurations |
| - soft, neutral, and firm amplitude levels |
| - stable pitch centers with consistent harmonic structure |
| - gentle and clear modal onset controls across low, mid, and high registers |
| - neutral vocal production without stylistic coloration |
|
|
| These characteristics make the dataset valuable for **AI speech and voice modeling**, **phonetics research**, **voice synthesis**, **phonation classification**, **vowel and register modeling**, **onset modeling**, and **human-aligned vocal control systems**. |
|
|
| Developed by **Harmonic Frontier Audio**, this preview follows *The Proteus Standard™* for dataset provenance, transparency, and ethical AI use. |

| ## 🎙️ About Modal Phonation |
|
|
| **Modal phonation** is the ordinary, efficiently voiced register used as a primary baseline for human vocal production. It is characterized by regular vocal-fold vibration, stable harmonic structure, and a naturally balanced relationship between airflow and vocal-fold engagement. |
|
|
| In this dataset, modal phonation is systematically represented across **low, mid, and high register zones**, five broad vowel configurations, and three amplitude levels. Separate onset controls provide additional examples of gentle and clear initiation into otherwise steady modal voicing. |
|
|
| These phenomena are foundational to: |
| - baseline speech and voice synthesis |
| - phonation-type and vocal-register classification |
| - vowel and formant-aware modeling |
| - amplitude-conditioned voice generation |
| - onset and attack modeling |
| - comparative study of non-modal and extended vocal behaviors |
|
|
| This dataset presents a **neutral, non-linguistic, non-performative representation** of modal phonation. |
| It is not designed to encode semantic speech content or musical performance, but rather to isolate **acoustic primitives** underlying stable natural voicing, vowel resonance, amplitude variation, and onset behavior. |

| ### Audio Files (.wav) |
|
|
| - Recorded at **96 kHz / 24-bit** WAV format |
| - Exported as **mono** |
| - Fade-ins and fade-outs of **3–5 ms** applied for consistency |
| - No compression, normalization, or creative processing applied |
| - High-pass filtered at ~40 Hz to remove subsonic rumble |
|
|
| This preview includes **4 representative audio files**, selected to demonstrate: |
| - **low-register open-vowel modal phonation** at soft amplitude |
| - **mid-register mid-front-vowel modal phonation** at firm amplitude |
| - **high-register high-front-vowel modal phonation** at neutral amplitude |
| - a **low-register gentle modal onset** followed by stable modal voicing |

| ## 🎤 Recording Notes |
|
|
| - Recorded in a treated studio environment using a **single-mic setup**: |
| - **Microphone:** Rode NT1-A condenser microphone |
| - **Recording chain:** Rode NT1-A → Zoom F8n Pro |
| - Captured at **96 kHz / 32-bit float**, rendered as **96 kHz / 24-bit** mono WAV for release. |
| - Performer positioned approximately **3.5 inches from the microphone**, with the microphone approximately **10–15 degrees off-axis**. |
| - Sustained modal vowels were recorded at approximately **6–8 seconds**, with onset controls approximately **4–6 seconds**. |
| - Exact pitches were not prescribed; performances were organized by **low, mid, and high register zones**. |
| - Stable pitch centers, consistent harmonic structure, and neutral vocal quality were preserved without stylistic coloration. |

|
| ## ⚡ Usage |
|
|
| This preview pack is designed for: |
|
|
| - Evaluation of Harmonic Frontier Audio dataset quality and structure |
| - Testing AI and DSP systems that model modal voicing, vowel resonance, amplitude, and onset behavior |
| - Research in phonetics, speech synthesis, phonation classification, and vocal-register modeling |
| - Creative and technical applications requiring clean, neutral sustained vocal primitives |
|
|
| 👉 **Note:** This is **not a full dataset**. |
| The complete **Modal Phonation** dataset includes a substantially larger matrix of sustained vowel primitives spanning five vowel configurations, three register zones, and soft/neutral/firm amplitudes, together with gentle and clear onset controls across low, mid, and high registers, and is available for licensing. |
