What do we want to do about measurements that are intended to span the entire track?  Is that a null-duration event, do we explicitly include the track duration?\r\n\r\nArguments for null-duration markup:\r\n\r\n  * easy to recognize\r\n  * semi-obvious semantics\r\n\r\nArguments for explicit durations:\r\n\r\n  * the annotations are more complete\r\n  * makes it easy to validate that the audio matches the annotation\r\n\r\nArguments for zero-duration:\r\n  * no good ones :)\r\n  * we should keep this convention solely for instantaneous events\r\n\r\nA third option might combine the first two: use null-duration for \"weak supervision\" (ie, the tag applies somewhere in the track but I don't know where), and full-duration for \"strong supervision\" (ie, this entire track is hip-hop)."},"comment":{"url":"https://api.github.com/repos/marl/jams/issues/comments/72097167","html_url":"https://github.com/marl/jams/issues/14#issuecomment-72097167","issue_url":"https://api.github.com/repos/marl/jams/issues/14","id":72097167,"user":{"login":"bmcfee","id":1190540,"avatar_url":"https://avatars.githubusercontent.com/u/1190540?v=3","gravatar_id":"","url":"https://api.github.com/users/bmcfee","html_url":"https://github.com/bmcfee","followers_url":"https://api.github.com/users/bmcfee/followers","following_url":"https://api.github.com/users/bmcfee/following{/other_user}","gists_url":"https://api.github.com/users/bmcfee/gists{/gist_id}","starred_url":"https://api.github.com/users/bmcfee/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/bmcfee/subscriptions","organizations_url":"https://api.github.com/users/bmcfee/orgs","repos_url":"https://api.github.com/users/bmcfee/repos","events_url":"https://api.github.com/users/bmcfee/events{/privacy}","received_events_url":"https://api.github.com/users/bmcfee/received_events","type":"User","site_admin":false},"created_at":"2015-01-29T20:22:50Z","updated_at":"2015-01-29T20:22:50Z","body":"> If you want a complete annotation you can just include the track duration in the file metadata.\r\n\r\nYeah, I guess I can buy that.  @ejhumphrey care to chime in?\r\n\r\n> Same applies for e.g. key and tempo\r\n\r\nFWIW, the isophonics key files are interval-timed.\r\n"}}
