Supported Datasets and Annotations

This table is provided as a guide for users to select appropriate datasets. The list of annotations omits some metadata for brevity, and we document the dataset’s primary annotations only.

“Downloadable” possible values:

• ✅ : Freely downloadable

• 🔑 : Available upon request

• 📺 : Youtube Links only

• ❌ : Not available

Annotation Types

The table above provides annotation types as a guide for choosing appropriate datasets. Here we provide a rough guide to the types in this table, but we strongly recommend reading the dataset specific documentation to ensure the data is as you expect. To see how these annotation types are implemented in Soundata see Annotations.

Tags

One or more string labels with corresponding confidence values. Tags do not have start or end times, and span the full duration of the clip. Tags are used to represent annotations for: * Acoustic Scene Classification (ASC) * Sound Event Classification (SEC) * Sound Event Detection (SED) - weak labels

When every Tags annotation in a dataset contains exactly one label, it is typically a multi-class problem. When Tags annotations contain varying numbers of labels (including 0), it is typically a multi-label problem.

Events

Sound events with a start time, end time, label, and confidence. Events are used to represent annotations for: * Sound Event Detection (SED) - strong labels
