Audio Events
|

|
|
---------------
|
||
|
|
|
||
|
|
`draft` `optional`
|
||
|
|
|
||
|
|
This NIP defines several new event kinds representing different types of audio track. These events
|
||
|
|
are _parameterized replaceable_ as defined in [NIP-01](./01.md) and deletable per [NIP-09](09.md).
|
||
|
|
|
||
|
|
Unlike a `kind 1` event with audio attached, audio events are intended to be surfaced in an audio-specific context
|
||
|
|
rather than in a general micro-blogging context.
|
||
|
|
|
||
|
|
The following kinds are defined by this NIP:
|
||
|
|
|
||
|
|
- `31337` represents a music track
|
||
|
|
- `31338` represents a podcast episode
|
||
|
|
|
||
|
|
The following tags are required:
|
||
|
|
|
||
|
|
- `d` is a unique identifier randomly generated by the client.
|
||
|
|
- `media` is the url of the media. This SHOULD NOT be read, but is required for backwards compatibility reasons.
|
||
|
|
- `imeta` is as described in [NIP 92](./92.md). Multiple `imeta` tags MAY be included to provide for different
|
||
|
|
use cases (e.g. streaming vs download).
|
||
|
|
- `title` is the title of the audio track
|
||
|
|
- `subject` is the title of the audio track (deprecated, but required for compatibility)
|
||
|
|
|
||
|
|
The following tags are optional:
|
||
|
|
|
||
|
|
- `i` is an external GUID in the format defined [here](https://github.com/MerryOscar/nips/commit/280eb498e0ac56b8f9356c1b7a88cc8b31579801).
|
||
|
|
- `c` is the track's value as defined by a given category.
|
||
|
|
- `website` is an external url to a website related to the track.
|
||
|
|
- `duration` is the duration of the audio track, in seconds.
|
||
|
|
- `published_at` is a timestamp representing the track's original publish date.
|
||
|
|
|
||
|
|
Note that artists, producers, SHOULD be referred to using both a plaintext `c` tag AND a conventional `p` tag when pubkey is available. When doing so, the `p` tag's petname MUST be the same as the `c` tag's value. In this way `c` tags can be used to indicate genre, as well as artist, producer, etc.
|
||
|
|
|
||
|
|
If included, `genre` and `subgenre` SHOULD be based on [this list](https://github.com/wavlake/genre-list).
|
||
|
|
|
||
|
|
`content` SHOULD be summary or description of the audio content.
|
||
|
|
|
||
|
|

|
||
|
|
|
||
