Task 2: ITD Threshold Changed to 62.5 μs

[Aidan Hogg]

Hi LAPers,

We hope you are all making good progress in the LAP challenge.

We just wanted to inform you that we have decided to increase the ITD threshold from 31.6 μs to 62.5 μs. We believe the original threshold was too strict, and even the baseline approaches often fail to pass it. 

Two things to note:

1. We have now updated the description document (with the updated threshold and plots).

   • https://imperialcollegelondon.app.box.com/s/w7b7dmqbuywuu1oktbrhehlgdfghhfm1 

2. We have now updated the evaluation code to reflect this new ITD threshold. 

   • https://spatial-audio-metrics.readthedocs.io/en/latest/api.html#module-spatialaudiometrics.lap_challenge (version: 0.0.6)

To use the new threshold, please use pip to install the latest version of the ‘spatialaudiometrics’ module. 

We apologise for this last-minute adjustment, but we hope this new threshold will be helpful. We made the change mainly because it seemed unfair that some submissions might have been disqualified only because of the ITD.

Cheers,

Aidan, along with the rest of the LAP team
