populating a reference library with the reference profile for the on-demand media;

collecting a first sample signature generated at a media presentation environment;

collecting a second sample signature generated at the media presentation environment;

determining that the second sample signature is consecutive to the first sample signature;

The computing system of claim 1 , wherein the wherein the report comprises one or more audience metrics associated with the media presentation environment; and wherein an audience metric of the one or more audience metrics is a length of exposure based on at least the first sample signature and the second sample signature.

7. The computing system of claim 1 , wherein the on-demand media comprises at least one of; a portion of a podcast, a standalone story, a clip, music, or a video.

8. A non-transitory computer-readable storage medium, having stored thereon program instructions that, upon execution by a processor, cause performance of a set of operations comprising:

detecting publication of on-demand media;

generating, in response to detection of the publication of the on-demand media, one or more reference signatures for the on-demand media;

collecting reference metadata associated with the on-demand media; generating a reference profile for the on-demand media, wherein the reference profile comprises the one or more reference signatures and the reference metadata;

populating a reference library with the reference profile for the on-demand media;

collecting a first sample signature generated at a media presentation environment;

collecting a second sample signature generated at the media presentation environment;

determining that the second sample signature is consecutive to the first sample signature;

determining an exposure for the on-demand media based on a match between the first sample signature and the one or more reference signatures and the second sample signature and the one or more reference signatures; and

outputting a report including the exposure of the on-demand media.

9. The non-transitory computer-readable storage medium of claim 8 , the set of operations further comprising:

downloading a copy of the on-demand media; and

generating the one or more reference signatures based on the copy of the on-demand media.

10. The non-transitory computer-readable storage medium of claim 8 , the set of operations further comprising:

collecting the reference metadata from a really simple syndication feed that is configured to host the on-demand media.

11. The non-transitory computer-readable storage medium of claim 8 , wherein the reference metadata comprises at least one of: a creator of the on-demand media, a first title of the on-demand media, a genre of the on-demand media, an episode number associated with the on-demand media, a second title of the episode associated with the on-demand media, a subject of the episode associated with the on-demand media, artwork associated with the on-demand media, a duration of the on-demand media, a platform at which the on-demand media is hosted, a location associated with the creator of the on-demand media, a time of publication of the on-demand media, a date of publication of the on-demand media, sponsors of the on-demand media, or information that identifies a guest in the episode associated with the on-demand media.

12. The non-transitory computer-readable storage medium of claim 8 , the set of operations further comprising:

recording a download request corresponding to the on-demand media based on detection of a request to download the on-demand media, wherein the download request comprises at least one of an internet protocol address of a device that issued the request to download the on-demand media or a user agent string associated with the device.

13. The non-transitory computer-readable storage medium of claim 8 , wherein the report comprises one or more audience metrics associated with the media presentation environment; and wherein an audience metric of the one or more audience metrics is a length of exposure based on at least the first sample signature and the second sample signature.

14. The non-transitory computer-readable storage medium of claim 8 , wherein the on-demand media comprises at least one of; a portion of a podcast, a standalone story, a clip, music, or a video.

15. A method comprising:

populating, in response to publication of on-demand media, a reference library with a reference profile for the on-demand media by:

generating, by executing an instruction with a processor, one or more reference signatures for the on-demand media;

collecting, by executing an instruction with the processor, reference metadata associated with the on-demand media; and

associating, by executing an instruction with the processor, the one or more reference signatures and the reference metadata in the reference library to generate the reference profile;

collecting, by executing an instruction with the processor, a first sample signature generated at a media presentation environment;

collecting, by executing an instruction with the processor, a second sample signature generated at the media presentation environment;

determining that the second sample signature is consecutive to the first sample signature;

determining, by executing an instruction with the processor, an exposure for the on-demand media based on a match between the first sample signature and the one or more reference signatures and the second sample signature and the one or more reference signatures; and

outputting a report including the exposure of the on-demand media.

16. The method of claim 15 , further comprising:

downloading a copy of the on-demand media; and

generating the one or more reference signatures based on the copy of the on-demand media.

17. The method of claim 15 , further comprising:

collecting the reference metadata from a really simple syndication feed that is configured to host the on-demand media.

18. The method of claim 15 , wherein the reference metadata comprises at least one of; a creator of the on-demand media, a first title of the on-demand media, a genre of the on-demand media, an episode number associated with the on-demand media, a second title of the episode associated with the on-demand media, a subject of the episode associated with the on-demand media, artwork associated with the on-demand media, a duration of the on-demand media, a platform at which the on-demand media is hosted, a location associated with the creator of the on-demand media, a time of publication of the on-demand media, a date of publication of the on-demand media, sponsors of the on-demand media, or information that identifies a guest in the episode associated with the on-demand media.

recording a download request corresponding to the on-demand media based on detection of a request to download the on-demand media, wherein the download request comprises at least one of an internet protocol address of a device that issued the request to download the on-demand media or user agent string associated with the device.

20. The method of claim 15 ,

wherein the report comprises one or more audience metrics associated with the media presentation environment; and wherein an audience metric of the one or more audience metrics is a length of exposure based on at least the first sample signature and the second sample signature.

21. The method of claim 15 , wherein the on-demand media includes comprises at least one of a portion of a podcast, a standalone story, a clip, music, or a video.
