Having successfully used the DPA’s d:screet Miniature Microphones during the filming of Mad Max: Fury Road, Sound Mixer Ben Osmo adopted for his next major film project – recording the audio for Ridley Scott’s 2017 sci-fi blockbuster, Alien:Covenant.

‘This film made unusual demands on the sound, costume and props departments because the cast not only had to wear radio mic transmitters but also an in-ear/comms set-up, which was part of the storyline,’ he explains. ‘We were predominantly using DPA for location sound recording, so we chose d:screet 4060 and 4061 lavalier mics, which we hid in clothing and spacesuits. We also used d:fine Headset Microphones on cast members as props – for example as talkback mics in space helmets.’

A sequel to Prometheus and the sixth instalment overall in the Alien film series, Alien:Covenant filming took place at Milford Sound in Fiordland National Park, New Zealand, and also at a disused water reservoir near Sydney. Bodyworn microphones for the film were supplied by Australian distributor, Amber Technology. In some scenes, the complexity of the spacesuit costumes worn by the main cast members and the need to remove space helmets to fit in with the storyline meant that up to three microphones were needed to capture the sound.

‘We would put one d:screet 4061 in the front of the space helmet with the cable inside the helmet’s foam supports and a small transmitter positioned in a cavity in the helmet,’ Osmo says: ‘A second 4061 was placed below the locking ring in the space suit, with the transmitter inside the suit, then a d:fine 66 Omnidirectional Headset Microphone was dressed under a cap and in shot as a practical talk back prop. The transmitter for that microphone was mounted under the backpack, alongside the Lectrosonics IFB R1a receiver.

‘This set-up allowed the cast to start the scene with their helmets off and then put them on while the camera was rolling without having to stop the dialogue. Having the three body mic alternatives gave postproduction the option of using whichever was most suitable. They also had the sound from the boom mics. Once the cast had their space helmets permanently on, we found that the d:fine 66 Headset Microphones were the best option.’

Working alongside Osmo on Alien:Covenant were Key Boom Operator Shanti Burn, Boom Operators Tod Moore and Mark van Kool (also in charge of radio mics) and Ben Yeadon, who was in charge of Cable/Utility.

‘Shanti did a great job in pre-production, liaising with the costume department and getting them sew special pouches into the costumes for both the Lectrosonics SMV and SMQV radio mic transmitters and the IFB1Ra receivers,’ Osmo says. ‘Tod set the transmitters, receivers, mics and in-ear pieces off set with the costume department as the cast were being dressed. Later, when Mark joined the sound crew, he replicated the setting up of the radio mics but also added his personal stamp on rigging the DPA mics in the costumes.’

‘Milford Sound was a breathtaking location and the acoustics for loud gunshots and explosions were amazing because the sound bounced off the mountains,’ Osmo reports. ‘However, the elements were often against us and we had many days when it was cold and rainy. Ridley loved the look, so we kept filming and got around the problems caused by the weather by waterproofing as much of the equipment as we could. The d:screet 4060 and 4061 microphones worked well in these damp, windy conditions and produced warm and even sound for most of the cast. When using the high EQ cap, they have a nice sparkle in the top end that lets the dialogue come through clothing evenly. There were a few occasions where we had to swap out mics when they got too damp, but after drying them out, they worked fine again.’

According to Osmo, the cast of Alien:Covenant were patient with the sound crew and accepted the need for some microphone tweaking between takes. Interior scenes were filmed on a shooting stage at Sydney’s Fox Studios and in some of these boom mics couldn’t be used because the corridors in the space ship were too tight.

‘In those situations we worked with the camera department and placed a d:screet 4060 with a small transmitter on the Steadicam operator, or on the camera itself,’ Osmo says. ‘This gave us prime position when the camera tracked backwards with the cast.’

One unusual aspect of this film was that the crew used sound cues for camera movements, props and SFX. This meant that Osmo had to come up with noises for the aliens – something he has great fun delivering. ‘I used some takes of our previous recordings of yells and blood curdling screams and recorded some guide yells from the actor who played the Alien,’ he explains. ‘I also used the d:screet 4060 mic that I used for my own comms/slate mic to record my own weird voice making some unusual sounds.

‘I imported a few takes into Pro Tools and edited a few versions when I had a minute.

Some were slowed and pitched down and mixed into two versions (young Neomorph and Alien). These were then played back on set as a guide for the cast to react to, via speakers or into their comms.

‘As in all films, it’s the collaboration of all departments that allows the sound department to achieve a good result,’ Osmo says. ‘That was certainly the case with Alien:Covenant.’
