Dataset Card for HTMOneShotLoopClassification

Dataset Summary

HTMOneShotLoopClassification is a dataset of 5,561 electronic music samples (one-shots and loops) from house, tech house, and minimal techno genres. Each sample is labeled with one of 8 stem categories and includes 55 extracted audio features for machine learning applications.

Supported Tasks and Leaderboards

Audio Classification: Multi-class classification into 8 stem categories
Baseline Performance: 85.41% accuracy using SVM with RBF kernel

Languages

Audio samples (no spoken language)
Metadata in English

Dataset Structure

Data Instances

Each instance contains:

Filename: Original audio file name
Stem Label: One of 8 categories (kick, snare, hihat, bass, synth, vocal, percussion, fx)
Category: Sample type (one-shots or loops)
55 Audio Features: Extracted using librosa

Data Fields

Field	Type	Description
filename	string	Original audio filename
stem	categorical	Target label (8 categories)
category	categorical	one-shots or loops
duration	float	Audio duration in seconds
sample_rate	integer	Sample rate (typically 44100 Hz)
rms	float	Root mean square energy
zcr	float	Zero crossing rate
spectral_centroid	float	Spectral centroid in Hz
...	...	(See metadata_schema.json for all 55 features)

Data Splits

Recommended splits:

Train: 80% (4,450 samples)
Validation: 10% (556 samples)
Test: 10% (556 samples)

Dataset Creation

Curation Rationale

The dataset was created to address the lack of curated electronic music sample datasets with:

High-quality professional samples
Consistent feature extraction
Genre-specific focus (house/tech house/minimal techno)
Both one-shots and loops

Source Data

Professional electronic music sample packs
Curated from house, tech house, and minimal techno collections
Quality-controlled and deduplicated

Annotations

Annotation process: Automatic categorization based on folder name patterns, with manual review for ambiguous cases
Annotators: Domain experts
Annotation guidelines: Based on standard electronic music production categories

Considerations for Using the Data

Social Impact

This dataset enables research in:

Automated music production tools
Audio classification systems
Electronic music analysis

Discussion of Biases

Genre Bias: Focused on house, tech house, and minimal techno (not all electronic music)
Class Balance: Good balance achieved (FX: 561, all categories within 80-130% of average)
Key Coverage: Not all categories have musical key information (only bass and synth have 100% coverage)

Other Known Limitations

Dataset size: 5,561 samples (moderate size)
Limited to specific sub-genres of electronic music
Some categories have low key coverage (important for harmonic mixing applications)
