# Dataset Card for HTMOneShotLoopClassification

## Dataset Description

- **Homepage**: https://github.com/itsuzef/HTMOneShotLoopClassification
- **Repository**: https://github.com/itsuzef/HTMOneShotLoopClassification
- **Paper**: [To be added - link to paper when published]
- **DOI**: [10.5281/zenodo.17872191](https://doi.org/10.5281/zenodo.17872191)

### 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)
