Re: Export of Track Lengths

I'd guess a fairly small subset. Because Audacity is such a versatile application, there are many, widely differing subsets (or as we tend to call them: "use cases").machineghost wrote: ↑Tue Apr 30, 2019 7:02 pmI do realize that this is only a concern for the subset of Audacity users who use the tool for presentations, and I have no idea how big that subset is; I just know that this feature would be very useful to that subset. My hope was that even if that subset was relatively small, the easy of implementation might help justify making the (hopefully small) effort to support them ... but I completely understand if it isn't.
One of my favourite features in Audacity is that it has a built-in scripting language called "Nyquist". Although only a small subset of users are likely to use Nyquist directly, indirectly it is one of the most widely used features. Nyquist is an interpreted language that runs straight from the plain text code (no need to compile), and with the addition of some special "header" comments, can be used by Audacity as "plug-ins".
Audacity ships with quite a few Nyquist plug-ins. In the Effect menu, the effects listed at the bottom (Adjustable Fade, Clip Fix, Crossfade Clips, ...) are Nyquist plug-ins. There are also a large number of optional plug-ins available, many of which were written to provide functionality required by subsets of Audacity users: https://wiki.audacityteam.org/wiki/Down ... t_Plug-ins
Plug-ins are a very good way of providing functionality that is required only by a subset of users, as it avoids adding "clutter" for other users. It would be nice if installing Nyquist plug-ins was easier, but we're working on that.
Perhaps won't need to if we can provide a plug-in to do the job.machineghost wrote: ↑Tue Apr 30, 2019 7:02 pmCould you please add the following bullet point to the end of "Other Import/Exports":Ability to export track length data as a text file (or even just as copy/paste-able text in a dialog). Use Case/Rationale: Audacity users who build presentations (where each track corresponds to a particular slide or other visualization in the presentation) need to know the length (and/or the exact start/end time) of each track, and the only way to get this information currently is to hand type it after selecting each track individually.
Originally the Audacity wiki was like Wikipedia in that anyone could set up an account and post directly to the wiki. To combat spam, restrictions on accounts were progressively increased, but even when manually verifying that user accounts were genuine, a lot of what was being posted was written so badly that it was often incomprehensible. We do not have the resources to adequately monitor, edit, rewrite submissions to a public wiki, so it is now available as a read-only addition to the manual. There is still a huge amount of cruft in the wiki that needs updating / revising / deleting, but the priority for the documentation crew is to keep the manual up to date.machineghost wrote: ↑Tue Apr 30, 2019 7:02 pmif you want feature requests submitted some other way (eg. via the page you linked ... although it's not editable so I don't know how anyone could request a feature there) it might make sense to link to it on this page
Our preferred way for Audacity users to submit feature request is via this forum. This allows Audacity users to comment and discuss feature requests before they are transferred to the wiki. A large number of requested features are for things that Audacity already has, so feature requests sometimes mutate into a discussion about how to improve an existing feature.
Thanks for the link. That's a pretty old page, and it has a note at the top for wiki editors, indicating that it needs some TLC. I've put that on my to-do list.machineghost wrote: ↑Tue Apr 30, 2019 7:02 pmit might make sense to link to it on this page: https://wiki.audacityteam.org/wiki/Reporting_Bugs
You're very welcome. Thank you for your feedback, and my apologies if my initial reply appeared dismissive - that wasn't the intention, but even emojis are limited in their ability to express moodmachineghost wrote: ↑Tue Apr 30, 2019 7:02 pmAnd one more time, just for good measure ... thanks for taking the time to help me with this "ticket"!
I'd be interested in your feedback on the Nyquist code that I posted - if it works for you, then I'd be happy to turn it into an installable plug-in and post it to the wiki plug-ins page so that it is available for everyone.
