Quick Start

ds = load_dataset("schismaudio/dynamic-percussion")

Dataset Description

The Dynamic Percussion Dataset is a collection of one-shot percussion samples recorded in an anechoic chamber at Tampere University. Audio is 44.1 kHz, 24-bit, mono WAV. Pre-calculated OpenL3 audio embeddings are included alongside the raw waveforms. The full dataset is approximately 174 MB.

Originally created as part of a Bachelor's thesis (Tampere University, 2020), the dataset was designed to support research in percussion sound classification and sample retrieval. The controlled anechoic recording environment provides clean, room-reflection-free samples.

Dataset Structure

Data Fields

Field	Type	Description
audio	Audio	WAV file at 44.1 kHz, 24-bit, mono
filename	string	Original filename
instrument	string	Percussion instrument label
embedding	Sequence[float]	Pre-calculated OpenL3 embedding vector

Data Splits

This dataset has no predefined splits. All samples are in the default train split.

Usage Examples

Load audio samples

from datasets import load_dataset

ds = load_dataset("schismaudio/dynamic-percussion")

sample = ds["train"][0]
print(sample["filename"], sample["instrument"])
# Access raw audio array and sampling rate
audio_array = sample["audio"]["array"]
sr = sample["audio"]["sampling_rate"]  # 44100

Use pre-calculated embeddings

import numpy as np
from datasets import load_dataset

ds = load_dataset("schismaudio/dynamic-percussion")

embeddings = np.array([s["embedding"] for s in ds["train"]])
labels = [s["instrument"] for s in ds["train"]]
print(f"Embedding matrix: {embeddings.shape}")

Dataset Creation

Source Data

All samples were recorded in an anechoic chamber at Tampere University using various percussion instruments. The anechoic environment ensures each sample is free of room reflections and background noise, making the recordings suitable as clean one-shot sources for synthesis, augmentation, and classification research.

Annotations

Instrument labels were assigned at recording time. OpenL3 embeddings were computed offline using the pre-trained music model.

Known Limitations

• Anechoic conditions: The recording environment does not match real-world studio or live settings. Models trained on this data may not generalize to reverberant or noisy conditions.
• Limited instrument diversity: The dataset covers a subset of percussion instruments; rare or regional instruments are not represented.
• Mono only: No stereo recordings are included.
