Reason: spelling correction
Assuming your output table is named "output," try this:
INSERT INTO [output] (audio, video, broadcast)
SELECT COUNT (audio.id) AS audio,
COUNT(video.id) AS video,
COUNT(broadcast.id) AS broadcast
FROM (audio INNER JOIN video ON audio.somecolumn = video.somecolumn)
INNER JOIN broadcast ON video.somecolumn = broadcast.somecolumn
WHERE audio.somecolumn = 'something'
Please post questions to the forums, where others may benefit.
