- You may be looking for Gareth Thomas.
Gareth Meirion Thomas was the sound recordist for scenes of Torchwood: Miracle Day filmed in the United Kingdom. He was thus credited on episodes where the UK was a principal setting, such as The Middle Men and The New World.
Thomas appears to have come up through the ranks at BBC Wales. He worked on a number of Welsh-language programmes, as well as some of BBC Wales' more prestigious English-language projects of the early 21st century. He was, for instance, director Euros Lyns sound recordist on Jean Marsh's Upstairs, Downstairs. He also was the sound recordist on The Indian Doctor starring Ayesha Dharker.
On some productions, though none in the DWU, he is credited as "Gareth Meirion".
