All teams are required to register prior to submission. Early registration will help us to plan the listening panel.

Key Dates including submission deadline.

1. What audio do I need to submit?

Signals should be submitted as 16-bit WAV files with a 32 kHz sampling rate, and 0 dB FS corresponds to 100 dB SPL, given the capabilities of the headsets used by the listening panel. See the page on listening tests for more information about reproduction levels from the headset. When playing signals to listeners we will then play them as is. The responsibility for the final signal level is therefore yours. It’s worth bearing in mind that should your signals overall seem too loud to be comfortable to a participant, they may well turn down the volume themselves. Also, there may be clipping in the evaluation block in some tasks if the processed signals are too large.

1.1. Task 1: Headphones

You must submit the following audio for all the signals in the evaluation set:

  • The VDBO (vocal, drums, bass, other) demixed signals for both left and right.
  • The left and right stereo signals output from the remixer.

For those replacing the whole enhancement block with another approach, just the left and right output signals from your enhancement processer are required.

1.2. Task 2: Car

You must submit the following audio for all the signals in the evaluation set:

  • The output processed music enhanced by the car stereo.

2. Code

We encourage you to make your code open source.

3. Technical report

  • The two page technical report must be submitted as a paper to the Cadenza-2023 Workshop. An author kit and submission instructions will be made available.
  • A draft of the report needs to be uploaded to the Google Drive along with your processed signals. The draft needs to be sufficiently complete for us to judge whether your system is compliant with the challenge rules.
  • Your report should include an abstract and introduction and sections on experimental setup/methodology including system information and model/network architecture, evaluation/results, discussion, conclusion and references. Please provide an estimation of the computational resources needed. You must describe any external data and pre-existing tools, software and models used.

4. Where do I submit the signals?

When you have registered you will receive a link to a Google Drive to which you will be able to securely upload your signals.

Materials uploaded will be visible to the Cadenza Team but not to other entrants.


Note, in order to use the Google Drive you will need to have a Google account. If you anticipate problems using Google then please make arrangements to send us the materials by other means, e.g., via a service such as WeTransfer or similar.
