The amateur orchestra I am in, the Cambridge Concert Orchestra, are involved in the Somme100 FILM project which means we'll be performing Laura Rossi's score alongside the silent film footage. To keep things synchronised our conductor is given a click track so that she can conduct us perfectly in sync with the film.
One challenge we are facing is what to use so that the click track is audible over the sound of a full orchestra, especially for the bits where we are all going for it. We tried a simple in-ear bud style headphone on the audio-out of an Android tablet and that was too quiet.
What should we use to keep the click-track audible for our conductor?
