FoleySet: A Multi-Level Human-Annotated Foley Sound Dataset

The pith
FoleySet supplies 10,000 human-annotated clips under a two-level taxonomy to support Foley classification, retrieval, and generation.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
We present FoleySet, a publicly available Foley dataset of 10,000 audio clips annotated with a two-level Foley taxonomy. This dataset provides a standardized, Creative Commons-licensed resource for data-driven Foley classification, retrieval, and generation.
What carries the argument
The two-level Foley taxonomy applied to annotate the 10,000 audio clips of human actions and prop interactions.
If this is right
- Models for Foley classification can be trained directly on the labeled clips.
- Retrieval systems can match sounds to specific on-screen actions using the taxonomy.
- Generative models can learn to produce new Foley audio from the annotated examples.
- Research groups gain a common, licensed benchmark for comparing methods.
Where Pith is reading between the lines
- The two-level structure could support hierarchical training where coarse labels regularize fine-grained predictions.
- Integration with video datasets might enable joint audio-visual models for automatic Foley creation.
- Widespread adoption could create shared evaluation protocols similar to those used in speech recognition.
Load-bearing premise
High-quality annotated Foley datasets for training remain scarce and the new dataset with its two-level taxonomy will serve as a useful standardized resource.
What would settle it
A controlled experiment in which classifiers or generators trained on FoleySet show no accuracy or quality gain over models trained only on prior smaller collections would indicate the dataset does not deliver the expected benefit.

read the original abstract
In audiovisual post-production, Foley refers to synchronous sound effects associated with human actions, such as footsteps, cloth rustle, and prop handling, that are recreated to match the on-screen movements and interactions of characters. These sounds are often recorded by professional Foley artists using physical props. This resource-intensive workflow has motivated data-driven research on Foley, including tasks such as classification, retrieval, and generation; however, high-quality annotated Foley datasets for training remain scarce. To address this gap, we present FoleySet, a publicly available Foley dataset of 10,000 audio clips annotated with a two-level Foley taxonomy. This dataset provides a standardized, Creative Commons-licensed resource for data-driven Foley classification, retrieval, and generation.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper presents FoleySet, a publicly available Creative Commons-licensed dataset of 10,000 audio clips annotated with a two-level Foley taxonomy, intended to address the scarcity of high-quality annotated resources for data-driven Foley classification, retrieval, and generation tasks.
Significance. If the annotations prove reliable and the taxonomy well-specified, the dataset could provide a useful standardized resource for Foley-related machine learning tasks. The contribution is a direct data release rather than a methodological advance, so its impact hinges entirely on the documented quality and reproducibility of the annotations.
major comments (2)
- [Abstract] Abstract: the central claims that the dataset is 'high-quality' and 'standardized' are unsupported because the manuscript provides no description of the annotation process, taxonomy construction, number of annotators, collection protocol, clip selection criteria, or any reliability statistics such as inter-annotator agreement.
- No section: without details on how the two-level taxonomy was defined or validated, it is impossible to assess whether the annotations meet the quality threshold asserted for training classification/retrieval/generation models.
Simulated Author's Rebuttal
We thank the referee for the constructive feedback. The comments correctly identify that the current manuscript lacks the necessary documentation on the annotation process and taxonomy to substantiate claims of high quality and standardization. We will address these points through revisions.

Referee: [Abstract] Abstract: the central claims that the dataset is 'high-quality' and 'standardized' are unsupported because the manuscript provides no description of the annotation process, taxonomy construction, number of annotators, collection protocol, clip selection criteria, or any reliability statistics such as inter-annotator agreement.
Authors: We agree that the manuscript as submitted does not include these details, which are required to support the stated claims. In the revised version we will add a dedicated Methods section describing the two-level taxonomy construction, annotation protocol, number of annotators and their qualifications, clip sourcing and selection criteria, and any computed reliability statistics including inter-annotator agreement. revision: yes

Referee: [—] No section: without details on how the two-level taxonomy was defined or validated, it is impossible to assess whether the annotations meet the quality threshold asserted for training classification/retrieval/generation models.
Authors: We accept this assessment. The revised manuscript will contain an explicit section on taxonomy definition, validation procedures, and supporting evidence so that readers can evaluate suitability for downstream tasks. revision: yes
Circularity Check
Dataset release contains no derivations or predictions
full rationale
The paper is a direct announcement of a new 10k-clip Foley audio dataset with a two-level taxonomy and CC license. No equations, fitted parameters, predictions, or derivation chains exist in the abstract or described content. The contribution is the resource itself; claims of standardization rest on the release rather than any self-referential reduction or self-citation load-bearing step. This is a standard non-circular dataset paper.

INTRODUCTION Foley refers to the synchronized reproduction of everyday sound effects for audiovisual media. Examples include footsteps, cloth movement, and object interactions such as doors opening or coins jingling. Unlike purely synthetic sound effects, Foley is often cre- ated and recorded in studio settings. In this process, Foley artists use a variet...

Existing audio taxonomies therefore show overlaps and inconsistencies in how Foley and other sound categories are labeled
TAXONOMY Foley is a commonly used term in audiovisual sound post-production; however, there is no universally accepted definition of its scope, and its boundary with the broader domain of sound effects re- mains blurred. Existing audio taxonomies therefore show overlaps and inconsistencies in how Foley and other sound categories are labeled. For example, ...

The work has two main contributions
CONCLUSION We presented FoleySet, a novel human-annotated Foley dataset built upon a consistent and data-informed taxonomy. The work has two main contributions. First, it addresses the need for a Foley- related dataset in an important yet underexplored subdomain of the broader field of sound effects, providing a resource that facilitates future Foley rese...
