+# Harmonic Frontier Audio – Breathing Cycles and Physiological Patterns (Preview, v0.95)
+
+**A high-fidelity human vocal dataset designed for AI training, speech research, and expressive voice modeling.**
+
+**Breathing Cycles and Physiological Patterns (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 **natural breathing cycles and physiological airflow patterns** — non-lexical respiratory behaviors captured as isolated human acoustic primitives for expressive audio modeling.
+
+The recordings emphasize:
+- relaxed and deeper inhale–exhale cycles
+- slow, extended, and meditative breathing
+- faster and shallow respiratory patterns
+- brief inhale and exhale holds
+- irregular breathing and reset breaths
+
+These characteristics make the dataset valuable for **AI speech modeling**, **expressive voice synthesis**, **breath-aware generative audio**, **physiological sound 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.  
+Learn more about the Proteus Standard → https://harmonicfrontieraudio.com/proteus-standard

+Full dataset details and licensing information are available at:

+
+## 🌬️ About Breathing Cycles and Physiological Patterns
+
+**Breathing cycles** consist of naturally coordinated inhalation and exhalation events whose rate, depth, duration, and transitions vary with physical and expressive state.  
+**Physiological breathing patterns** include controlled variations such as extended breaths, shallow cycles, pauses, irregular timing, and reset breaths that occur independently of lexical speech.
+
+These phenomena are foundational to:
+- naturalistic speech and voice synthesis
+- breath-aware expressive audio modeling
+- physiological and respiratory sound research
+- embodied and multimodal agent behavior
+- realistic timing and transition modeling around vocal activity
+
+This dataset presents a **neutral, non-linguistic, non-performative representation** of human respiratory behavior.  
+It is not designed to encode semantic speech content, but rather to isolate **acoustic primitives** that underlie natural breathing, respiratory timing, and physiological airflow variation.
+
+---
+
+## 📂 Contents
+
+### 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 **3 representative audio files**, selected to demonstrate:
+- natural inhale–exhale cycle behavior
+- variation in breath depth and pacing
+- physiological airflow and respiratory timing characteristics
+
+---
+
+### Metadata (.csv)
+
+Includes structured fields for:
+- file name
+- sound source type
+- airflow type
+- phonation type
+- gesture and articulation descriptors
+- microphone and recording chain
+- sample rate, bit depth, and dataset version
+
+Metadata follows the **Harmonic Frontier Audio – Foundations** schema.

+
+## 🎤 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**.
+- Natural respiratory dynamics, airflow texture, and subtle breath noise were preserved to retain acoustic realism.
+

+
+## ⚡ Usage
+
+This preview pack is designed for:
+
+- Evaluation of Harmonic Frontier Audio dataset quality and structure  
+- Testing AI and DSP systems that model breathing, respiratory timing, and physiological airflow  
+- Research in speech synthesis, expressive vocal modeling, and breath-aware audio systems  
+- Creative sound design involving natural human breath and respiratory texture
