What do Location Managers do all day?

---

It’s a question that is often asked by my family who fondly believe I spend my time in idle chit-chat and gossip with high-powered film and media executives sipping skinny-latte Mocachinos (whatever they are!) and eating sushi. But consider the following exciting ‘James Bond’ style scenario. “Our hero and heroine are on the run, driving fast throug...

How The SADiE LRX2 Is Making Location Multitrack Recordin...

---

Nearly twenty years ago I saw one of the first SADiE Digital Audio Workstations, which were just starting to make their mark as the first cost effective computer sound editor. I was so impressed with the concept that I immediately wanted one, even though I had no professional use for it whatsoever. Most of my work (particularly then) was in TV docu...

Total audio has been around for 12 years now and I worked for the BBC for 13 years prior to that, I resigned in 1996 as a senior sound supervisor based at Pebble Mill. I firmly believe that sound is only noticed twice, the first time it was distorted and the second time it wasn’t there. When it all goes swimmingly it’s rarely mentioned. In the last...

RF Condenser Microphones why they are so good in the wet

A question I am often asked when people discover who I work for is “Why are ‘RF condenser’ microphones so good in the wet, being so much less susceptible to humidity problems than the more common ‘AF condenser’ microphones?”Basically, AF capacitor microphones use the capsule as a capacitor to store charge. With one fixed plate and the other free to...

Audio acquisition and production

---

Remembering the days when the average 'portable' sound recorder was heavy enough to induce a hernia, I have high respect for the capabilities of modern digital audio devices. Not least the solid-state recorders that have emerged as successors to the Sony-originated DAT and MiniDisk formats. But avoid anything that lacks XLR connectors unless you ar...

The Fairlight Time Machine

Just over fifty years ago, the then Soviet Union launched the first satellite into orbit around our planet. At that time the USA and USSR were in the depths of the cold war and the launch of Sputnik 1 on the 4th October 1957 was the starting gun for the space race. The winner would be the country to successfully land the first human being on the Mo...
