When Netflix updated its sound mix specifications to make Dolby Atmos the preferred delivery format for original content, it sent a quiet shockwave through post-production houses worldwide. The message was unambiguous: immersive audio is no longer a premium extra. It is the baseline.

For Scottish studios — long accustomed to punching above their weight on drama, documentary and factual programming — the question became urgent. Build an Atmos room, or lose the work to London, Manchester, or Dublin?

The good news is that Glasgow, at least, has already answered.

Glasgow leads the charge

Savalas Post, the multi-award-winning facility at Film City Glasgow, now operates a dedicated Dolby Atmos mix stage alongside its Dolby Premier-accredited theatres. Theatre 3, fitted with a 7.1.4 monitoring configuration by PSI Audio, QSC and KEF with acoustics by WhiteMark, handles Atmos, 5.1 and stereo formats. The facility's credits speak for themselves: BBC's Vigil, BBC's Shetland, and Britbox's Crime have all passed through its mix rooms.

Savalas has gone further still, forming a strategic partnership with fellow Glasgow outfit BSQUARED under the Savalas x BSQUARED banner, consolidating picture finishing and audio post under one creative umbrella with Dolby Atmos capabilities front and centre.

Across Glasgow's Southside, Serious Facilities — another veteran house dating back to 1998 — lists Dolby Atmos mastering among its services alongside Dolby Vision grading. With more than 40 rooms and over 100 remote edit setups spread across three Glasgow sites and a London outpost, the company handles full 4K HDR and surround sound post at scale. Its recent credits include BBC's Dragon's Den, Channel 4's Davina McCall's Pill Revolution, and Alibi's Annika.

What Atmos actually means

For readers less familiar with the technology: traditional surround sound (5.1 or 7.1) assigns audio to fixed channels — left, right, centre, surrounds and subwoofer. Dolby Atmos adds an object-based layer. Individual sounds — a helicopter, a whispered voice, rain — can be placed and moved anywhere in three-dimensional space, including overhead. The result, when done well, is genuinely immersive.

Netflix's current specifications require Atmos mixes to be created in rooms with a minimum 7.1.4 speaker configuration — seven ear-level speakers, one subwoofer, and four overhead channels. The final deliverable is a BWAV ADM file at 48kHz/24-bit, with dialogue, music and effects separated across beds and objects. Crucially, Netflix does not require Dolby certification for home-entertainment Atmos mix rooms, which lowers the barrier to entry somewhat.

But "somewhat" is doing heavy lifting in that sentence.

The cost of entry

The Dolby Atmos Production Suite software itself is relatively modest — a few hundred pounds. The real expense lies in the room. Acoustic treatment must be extended to handle reflections from overhead and surround speakers that traditional stereo rooms were never designed for. A minimum of 12 speakers plus subwoofer need purchasing, positioning and calibrating. Monitor controllers capable of handling that many channels — such as the JBL Intonato 24 or Avid MTRX Studio — can run to several thousand pounds alone.

For a purpose-built Atmos post-production theatre to cinema specification, studio designers quote substantial six-figure sums. A nearfield home-entertainment mix room — which is what most TV drama and factual work requires — can be achieved more affordably, but still represents a significant capital commitment for an independent facility.

The competition

This is where context matters. dock10, the anchor post house at Manchester's MediaCity, offers Dolby Atmos mixing as standard across its audio suites, backed by Avid Pro Tools and the deep pockets of a facility embedded within the BBC and ITV ecosystem. In Dublin, Windmill Lane recently consolidated all five of its mix suites — including a dedicated Atmos room — under one roof at Herbert Street, fresh from work on Disney+'s Kizazi Moto and Netflix's Bodkin.

These are purpose-built, heavily capitalised operations. Scotland's facilities are competing with them for the same commissioning editors.

A safety net from Screen Scotland

There is institutional support. Screen Scotland relaunched its £1 million Project Post Fund in 2025, offering grants of up to £100,000 to productions that undertake post-production wholly or partially in Scotland. The fund has already helped secure high-profile projects — HBO's The Penguin among them — and is designed precisely to stop post-production work migrating south.

Meanwhile, Edinburgh College opened a Dolby Atmos 7.1.4 teaching studio in late 2024, built around the Audient ORIA immersive audio interface. Head of School Jonathan Bennett described it as preparing students for an industry "moving more and more towards spatial and interactive audio." It is a pipeline investment: training the next generation of re-recording mixers who can staff Scotland's Atmos rooms.

The verdict

The picture is more encouraging than the doom-mongers might suggest. Glasgow has at least two established post houses with Atmos capability, Edinburgh is training future talent, and Screen Scotland is actively funding the ecosystem. The infrastructure gap with Manchester and Dublin is real but narrowing.

The risk is complacency. Atmos is not a passing fashion — it is baked into the delivery specifications of every major streaming platform. Studios that delay investment will find themselves subcontracting their most lucrative work to facilities that did not hesitate. Scotland's post-production sector has the talent. The question now is whether it has the sustained investment to match.
