Indeed observers of the Dutch Meteor Society succeeded in recording sonic booms
of a bright fireball, supposedly a deeply penetrating member of the Taurid/Enke
complex (we also have double station photographs if this event). The recordings
were made by Hi-8 camcorders which were operating to catch meteors at the same
time. The time delay between the event and the booms was about three minutes.
You can download the recordings (in Microsoft Windows *.wav format) from the
homepage of the Dutch Meteor Society:

Look at the item "photo's" and then the sub-directory "taurid fireball".
The material was also sent to Revelle for further analysis.
Hope you like them,
