Webcast Metrics® has been measuring the audio streaming space since 2008, providing the industry with monthly Rankers that list the top-performing digital audio stations and networks across the globe, including iHeart, Pandora, Spotify, NPR, Prisa Radio (ES), Grupo Acir (Mexico), and Grupo JBFM (Brazil).
The only streaming audio measurement service in the world that is accredited by the Media Rating Council (MRC), Webcast Metrics data has become the currency for streaming audio advertising in the US, making it easy for advertisers and brands to determine the best place and time to reach their target audience.
In order to use this data effectively, understanding it is key. To help, we've compiled some basic information on the data that Webcast Metrics provides below.

SS is the number of stream requests that were listened to for at least 1-minute. This is the total amount of time that the stream was played.
Active Sessions (AS)
AS is the number of sessions that were active for at least 1-minute. The total number of active sessions represents the number of people who listened to the audio at a given time.
Total Listening Hours (TLH)
TLH is the total number of hours that a station played for at least 1-minute.
Average Active Sessions (AAS)
AAS is the total listening hours (TLH) divided by the number of hours.

AQH is the average number of listeners who streamed a particular station for at least 5-minutes during a 15-minute period.
Average Time Spent Listening (ATSL)
ATSL is the average number of hours that each session was streamed.
CUME
Cume is the number of unique listeners who streamed a particular audio feed for at least 5-minutes during a 15-minute period. A unique listener is an individual person who listened to the stream. This is usually tracked and calculated through their IP address.
