Audio post house Aquarium has cut its outgoings by about 20% in the face of shrinking production budgets.

The Soho-based, Bafta-winning sound facility has made the move so it can “maintain high levels of creativity” and has urged smaller facilities to consider following suit.

Head of operations Sean O’Shea said the company was using freelancers more effectively.

“We staff up when we are busy, and still have the same people mixing, supervising and performing quality control.

“But the key is not investing in new studios or new space, and we do everything we can to keep out of expensive rooms,” he said.

O’Shea said the reaction from producers with reduced budgets had been positive, and that Aquarium had seen a rise in the amount.
