Currently the exported cvs only includes timestamps and values for frames where pitch is detected (i.e. for silent frames nothing is returned). For using the exported annotations for evaluation, it would be more useful if a timestamp and frequency value were returned for every frame, where frames for which no pitch was detected have a frequency value of 0.
Also, I think being able to import an annotation from a file is going to be pretty important when people start correcting the f0 track, otherwise there's no way to save your work and come back to it later.

Import export pitch track is resolved.
But Justins additional feature request for the output of unvoiced frames has not been dealt with. My impression is that Justin has "just got on with it", but it is definitely something we could do. I'll make a new issue for that though.

For our immediate use of Tony yes, we just got on with it - by writing a script to impute the missing timestamps and corresponding 0 Hz values. I'd very much advocate to having this built into Tony, primarily so that the output conforms to the standard format used in most other pitch tracking environments, but also because this way the output would be a complete time-series, which I think is all-in-all a better representation.
