MIREX HOME

Welcome to MIREX 2026

After a break of 3 years, we want to bring back the MIREX (Music Information Retrieval Evaluation eXchange) competition starting from 2024. We want to bring in new tasks, benchmarks, and datasets in response to the rapid development of computer music research.

The MIREX community will hold its annual meeting as part of The International Society for Music Information Retrieval Conference. This year, the conference will be held in Abu Dhabi, UAE from November 8-12, 2026, possibly with an online component.

In a long run, we want to make MIREX a platform for researchers to share their latest research results, to compare their systems with others, and to promote the development of the field.

Call for Challenges

Starting with 2024, we invite the ISMIR community to propose new research challenges that address cutting-edge problems in Music Information Retrieval (MIR). These challenges should aim to push the boundaries of current research and foster innovation in the field.

We also welcome challenge sponsors from both industry and research institutions, particularly those willing to contribute datasets and computational resources to support the competition.

For the format and requirements for the challenge proposal, please go to 2026:Call for Challenges.

Task Captain Responsibilities:

• Register on the MIREX Wiki and maintain a task description page.
• Collect submissions via the MIREX submission server (or provide customized submission instructions).
• Execute and evaluate the submissions.
• Report results to MIREX and create a results page on the MIREX Wiki.
• (Optional) Present a MIREX task captain poster at the Late-Breaking and Demo (LBD) session at ISMIR 2026.

What's new:

In MIREX 2026, we introduce two special calls for challenges:

1. Novel evaluation pipelines

There is a growing need for new evaluation methodologies. We welcome challenge proposals that introduce novel evaluation pipelines, including but not limited to the evaluation of generative models, interactive systems, and other emerging paradigms.

2. Evaluation under limited resources

In addition to state-of-the-art systems, MIREX aims to better support researchers and research areas with limited resources. We welcome challenge proposals that focus on underrepresented research areas, music genres, or research communities.

Furthermore, all task captains are encouraged to report key resource indicators for each submission, including:

• training data size
• model size
• other computational resources used in model development

How to Participate
