Dataset Overview: Pop Rock Hybrid Stem Dataset (cat001)

This dataset contains a curated collection of original instrumental music designed for commercial and research applications in music analysis, audio modeling, and production workflows.

Every composition, arrangement, performance, sound design element, and production decision was created entirely through human musical and technical processes. All music contained in this dataset is 100% human-made (is_human_created: TRUE).

Access Requirements: This repository uses Hugging Face access requests. Access provides documentation and representative metadata samples only. Commercial use, model training, or deployment of the licensed audio assets requires a separate commercial license and applicable purchase documentation.

Commercial Licensing & Inquiries

Pop Rock Hybrid Stem Dataset (cat001) is available under a non-exclusive commercial license. The Hugging Face repository provides documentation, metadata samples, and dataset previews; commercial audio assets are not distributed through this repository.

For commercial licensing, AI/model-training inquiries, enterprise procurement, or evaluation requests, contact us through the licensing contact provided in the official licensing materials.

Product Delivery Structure

The dataset is highly controlled and structured around a seed-and-variation system to enable comparative analysis of arrangement, density, groove, and instrumentation changes across related compositions.

Data Fields & Manifest Schemas

1. Track Metadata Master Columns (03_track_metadata_master.csv)

Each row in the master metadata log maps granular compositional, technical, and architectural features of the audio files:

• —catalog_id: Identifier for the dataset volume group (e.g., cat001).
• —track_id: Unique identifier assigned to the song group.
• —title: Name of the musical composition.
• —variation: Structural category (seed, v01_density, etc.).
• —bpm: Beats per minute.
• —key: Musical key center.
• —duration_seconds: Precise length of the audio asset.
• —sample_rate: Audio sampling frequency (Hz).
• —bit_depth: Bit precision.
• —channels: Number of audio paths.
• —genre: Composed musical styles.
• —mood: Emotional or artistic descriptors.
• —time_signature: Meter of the piece.
• —file_name: System filename.
• —file_type: Distinction between fullmix and stem.
• —stem_name: Architecture assignment (rhythm, harmony, fx, or empty for fullmix).
• —variation_rule: Applied structural transformation rule.
• —lead_instrument: Primary melodic focal point instrument.
• —primary_instrumentation: List of all instrumentation present across the entire composition cluster (the parent seed and all its variations). This attribute remains constant across a cluster regardless of whether specific instruments are muted in a density variation.
• —is_human_created: Logical verification flag (TRUE).
• —vocal_presence: Textual indicator of vocal content.
• —audio_integrity: Sourcing and tracking verification state.
• —licensing_clearance: Rights clearance state.
• —asset_id: Globally unique identifier.

2. Asset Manifest Columns (06_asset_manifest.csv)

Maps every discrete audio file to its explicit relative folder path and SHA-256 fingerprint:

• —asset_id: Unique string key pairing with the master metadata sheet.
• —file_path: Relative repository directory path to the target file.
• —file_hash: Unique cryptographic verification signature.

Technical Audio Specifications

Structural Synchronization

• —Sample Accuracy: All variations and stems are strictly sample-aligned to their parent seed.
• —Phase Alignment: Stems are delivered phase-locked for transparent summing and sub-mixing workflows.
• —Grid Alignment: All audio files start and end precisely on grid musical boundaries to support seamless looping and temporal slicing.

Variation Specifications

Each seed composition is accompanied by multiple engineered variations derived from the same core musical material:

• —Seed: Original full arrangement with full instrumentation.
• —v01_density (No Drums/Bass): Reduced rhythmic foundation, emphasis on harmonic and melodic layers.
• —v02_density (Rhythm Focused): Drums, bass, and lead instrument only.
• —v03_groove: Rhythmic re-interpretation with substituted drum programming.
• —v04_sibling: Instrumentation substitution while preserving compositional structure.

Stem Architecture

Each track layout features a strict 3-Stem Schema:

1. 1.01_rhythm.wav: Drums, percussion, and bass lines.
2. 2.02_harmony.wav: Guitars, plucked strings, piano, keyboards, and synth pads.
3. 3.03_fx.wav: Special effects, transitions, and atmospheric sound design layers.

Note on Stem Consolidation: Individual instrument stems have been bounce-consolidated to reduce exposure of isolated performances while preserving structural utility. In selected density-reduced variations, a subtle harmonic companion layer has been introduced into the lead keys/piano stem group to maintain multi-source stem consistency in sparse arrangements.

Quality Assurance & Licensing Terms

• —Clipping Prevention: All delivered assets are programmatically verified clip-free to maintain dynamic integrity.
• —Render Integrity: All files maintain a unified, unchanging render pipeline to ensure absolute processing consistency across the entire repository.
• —Commercial Licensing: This dataset is distributed under a proprietary, non-exclusive commercial license (license: other).
• —Access Requirements: Content is gated. Commercial use, model training, or deployment requires a valid purchase certificate and clearance key corresponding to your asset_id mapping.
