The recordings highlight the instrument’s distinct nasal resonance, rapid transient response, and expressive harmonic coloration, making it valuable for **AI music modeling**, **timbre classification**, **acoustic analysis**, and **cross-cultural sound synthesis** research. 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: https://harmonicfrontieraudio.com/datasets/kazoo It offers clean, consistent audio files that capture the Kazoo’s playful yet harmonically rich character across sustained tones, triads, glissandi, and articulation patterns. If you find this dataset useful, please consider giving it a 🤍 on Hugging Face to help others discover it. --- ## 🎶 About the Kazoo The **Kazoo** is a buzzing aerophone / membranophone most commonly used in folk, novelty, and participatory musical settings. Its sound is produced when the performer vocalizes into the instrument, causing a membrane to vibrate and impart a distinctive **buzzing, nasally-modulated character**. Though simple in construction, the Kazoo is capable of surprising expressive range — from smooth glissandi to highly articulated tongued gestures. This preview dataset was designed to capture the instrument’s **core articulations neutrally**, without stylistic coloration, offering a universal training source for AI and research applications. --- ## 📂 Contents ### **Audio Files (.wav)** - Recorded at **96 kHz / 24-bit** WAV format - Exported as **mono** - Fade-ins and fade-outs of **3–5 ms** for transient consistency - DC offset checked — **none detected** - High-pass filtered at ~40 Hz to reduce subsonic rumble - No EQ, compression, saturation, or post-processing applied ### **Categories in this Preview** 1. **Sustain** - Single sustained tones across multiple pitches - Includes vibrato and non-vibrato variations 2. **Glissando** - Smooth pitch slides (e.g., E→E, G→G) demonstrating membrane continuity 3. **Tonguing / Articulation** - Short, percussive bursts with distinct transient character 4. **Triads (Staccato)** - Rapid three-note sequences created through vocalized changes - Includes C–E–G, F–A–C, G–B–D patterns --- ## **Metadata (.csv)** Includes structured fields for file name, category, articulation, note pitch, vibrato status, microphone used, channel configuration, sample rate, bit depth, recording chain, and dataset version. Metadata was hand-verified for consistency and accuracy according to Harmonic Frontier Audio standards. --- ## 🎤 Recording Notes - Recorded in a treated studio environment with: - **Microphone:** RØDE NT1-A (large-diaphragm condenser) - Positioned 8–10″ from the instrument for balanced capture - Recording chain: **RØDE NT1-A → Zoom F8n Pro (32-bit float capture)** Exported as **96 kHz / 24-bit mono WAV** for release - No noise reduction or dynamic processing used — transient integrity preserved - Natural dynamics retained for realistic ML training behavior --- ## 🌈 Spectrogram Preview Below is a spectrogram showing the Kazoo’s characteristic harmonic energy and buzzing membrane structure: ![Spectrogram Preview](Spectrogram_Preview.png) --- ## 🎧 Demonstration Audio This repository includes **three audio examples** for listening and comparison: **1. Dataset in musical context (mixed & mastered)** A brief musical excerpt demonstrating the Kazoo Preview dataset integrated into a musical arrangement, highlighting expressive timbre and real-world usability. **Track:** *“Kazoo Example”* **Producer:** Blake Pullen **Source Audio:** Harmonic Frontier Audio – Kazoo (Preview) **2. Raw dataset recording** An unprocessed audio excerpt taken directly from the dataset’s audio files, representing the actual licensed source material without musical context or processing. **3. AI-generated reference (timbral substitution)** A fully AI-generated reference created without using any Harmonic Frontier Audio recordings. While the model reconstructs the melodic content of the prompt, it replaces the kazoo with a toy xylophone–like timbre, reflecting a lack of kazoo representation in typical training data. This example is included to illustrate current limitations in timbral modeling. --- ## 📜 Demo & Licensing Note The `Demos/` folder contains **demonstration material only**. **Only the raw recordings in the dataset audio files constitute the licensed dataset.** AI-generated reference tracks are **not part of the dataset** and are **not licensed for training or reuse**. --- ## 🪶 Production Notes - Instrumental accompaniment in the contextual demo was generated using **Suno (Pro plan)** under a commercial license. - All dataset recordings were **performed, recorded, and produced by Blake Pullen** for Harmonic Frontier Audio. --- ## ⚡ Usage This preview dataset is designed for: - **Evaluation** of Harmonic Frontier Audio dataset structure and fidelity - **Testing** AI and DSP systems that model membranophones and vocal-modulated instruments - **Creative sound design**, **instrument synthesis**, and **timbre modeling** - **Classification and recognition research** 👉 Note: This is **not a full dataset**. The complete Harmonic Frontier Audio **Kazoo** dataset will include: - Full pitch range coverage - Extended articulations and dynamic layers - Additional gesture types (trills, flutter-vocalizations, rhythmic motifs) - Velocities and spectral variations --- ## 💡 Full Dataset Availability This is a **preview pack** from the *Novelty Gems Cabinet* family. The complete dataset — with expanded articulations — will be available for **licensing**.
