Description
Cadenza
This is the submission data for the listening over headphones task from the First Cadenza Machine Learning Challenge (CAD1).
The Cadenza Challenges are improving music production and processing for people with a hearing loss. According to The World Health Organization, 430 million people worldwide have a disabling hearing loss. Studies show that not being able to understand lyrics is an important problem to tackle for those with hearing loss. Consequently, this task is about improving the intelligibility of lyrics when listening to pop/rock over headphones. But this needs to be done without losing too much audio quality - you can't improve intelligibility just by turning off the rest of the band! We will be using one metric for intelligibility and another metric for audio quality, and giving you different targets to explore the balance between these metrics.
Please see the Cadenza website for a full description of the data
Technical info (English)
This dataset contains the submission audio signals for the CAD1 task1. The signals correspond to 30-second segments of 49 tracks of the MUSDB18-HQ test split. The signals were processed according the CAD1 requirements. Please refer to the Cadenza challenge website and to the paper for details.
Total number of audio samples: 25,971.
Description of files:
- CAD1_data.zip: package containing the audio signals
- listeners.json: JSON file with the anonimized listeners' audiograms.
- musdb18.test.json: JSON file with the 49 MUSDB18-HQ tracks included.
- musdb18.segments.json: JSON file with details of the 30-second segments used.
- HAAQI_scores.csv: CSV file with HAAQI scores
The audio signals are organised as:
<TEAM_ID>/<Listener_ID>/<Listener_ID>_<Track_ID>_remix.flac
where:
- TEAM_ID: 9 unique ids to identify each Team.
- Listener_ID: 53 unique ids to identify each listener.

Listener Panel Data
The data from the listener panel is contained in two files:
- CAD1_anon_listener_panel_data.csv: anonimized listener panel scores
- CAD1_anon_audiogram_data.xlsx: anonimized audiograms organised for listener panel analysis
