<ul></ul><p>Hi all,</p>
<p>I know this is a little out of the blue but I recently had to revisit this issue and wanted to bounce this topic back into everyone's mental space.</p>
<p>For running our evaluation experiments for medleydb we had to add all the missing 0's since mir_eval (and MIREX) expects 0's for silent frames. Eventually we wrote a script to do this "imputation" for all Tony files which worked, but it turned out to be trickier to get right than we initially anticipated.</p>
<p>This issue has now resurfaced when I was contacted by a student using Tony to create f0 annotations (yay!) who is interested in using them for evaluation with mir_eval (again, yay). So basically they're in the same place we were - and I think so will be anyone using Tony + mir_eval for evaluating f0 tracking algorithms, which, hopefully, will be everyone in the near future :)</p>
<p>So, whilst I acknowledge Matthias's concern, I think the stronger argument here is that this is an established enough convention such that a lot of people would find it really useful if Tony did output [timestamp,0] for silent frames. If possible it could be made optional (e.g. via a checkbox in settings), in which case I'd have the default behavior be to yes return zeros, but with the option to not return them if the user so desires.</p>
