HTMOneShotLoopClassification

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.

The dataset is designed for:

Audio classification tasks
Stem category prediction
Feature engineering research
Electronic music analysis

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)

Note: Good class balance (FX: 561 samples, Hihat: 907 samples). All categories within 80-130% of average.

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

Category Notes:

Hihat (907 samples): Most represented category because it includes multiple cymbal types (closed hihats, open hihats, ride cymbals, crash cymbals) essential for rhythmic patterns
Bass & Synth (100% key coverage): Key information is critical for these melodic categories to enable harmonic mixing and prevent dissonance
Vocal (45.1% key coverage): Samples without keys are primarily spoken word, vocal chops, and non-melodic elements; melodic vocals have key information

Annotations

Annotation process: Manual categorization by stem type
Annotators: Domain experts
Annotation guidelines: Based on standard electronic music production categories

Personal and Sensitive Information

No personal or sensitive information is included. All samples are from commercial sample packs or original productions.

Considerations for Using the Data

Social Impact of Dataset

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)
