Released in 1957, The Nagra III represented a technological breakthrough, going on to become the most popular Nagra ever built, with over 10,000 units sold. The Nagra III's development aimed to create a self-contained, high-quality portable recorder, and not only did they succeed, but did so on an unprecedented scale.
Many institutions and industries would go on to make use of the Nagra III for a variety of reasons, but there is one arena in which the Nagra III shone that made even its designers raise an eyebrow, and that’s spycraft.
The Designers Who Raised Their Brows
Quite characteristically, the team behind Nagra is not too focused on their own story, much preferring to let their products speak for them.
Starting out in Switzerland in the early 1950s and helmed by Stefan Kudelski, Nagra Audio did not take long to achieve acclaim.
Their approach off the bat was to create long-lasting, effective equipment that can be used in high-stakes environments. In essence, they would bring perfectionism to sound equipment, and industries across the board ate it up.
Not long after their establishment, Nagra Audio would go on to release their best-performing product to date, The Nagra III, earning them legendary status in a plethora of fields.
Nagra products have and still are seen in industries such as film and media, scientific research, commercial entertainment, linguistics research, and even in-studio recording.
One might notice a trend among these fields. Wherever precision sound engineering was needed, even in literal laboratory conditions, Nagra was called.
Nagra III: Embodying Precision Sound Engineering
It is no wonder Nagra products have been used in scientific research, because each piece of equipment they create is a product of rigorous scientific research. See, The Nagra III, as widespread and successful as it was, was not some product of miraculous intervention.
Instead, Nagra put in hundreds of hours of meticulous study to reach that point. They looked into exactly what worked and did not work with each of their models, each time refining their process to answer any concerns that arose.
As a result, The Nagra III is a powerhouse. Each piece works in tandem with another to create that level of performance. The capstan, a functional part of the motor shaft in the Nagra III, and the wheel, with 400 precisely engineered cogs, sit on the same shaft.
Turning the wheel induces an alternating current and adjacent magnetic hold which, once a signal is produced, ensures rigorous proportionality to not only the capstan, but the linear speed of the tape. A servo mechanism also ensures this speed is constant.
The result is a recording device with incredible ability. Not only did its design offer unprecedented reliability, but it offered its user something they’d never had before: a chance to move around whilst recording.
That’s Audio, Nagra Audio
Here’s where the eyebrows raise. Perhaps as a result of The Nagra III’s ability to move around and record, the company began to attract new clientele.
Of course, among them were the film industry giants seeking this new, efficient way to record sounds like never before.
Some notable names include Star Wars and Apocalypse Now. Also among these new clients, however, were foreign intelligence agencies. More specifically, as Nagra began to receive acclaim, they received a knock at the proverbial door from none other than the CIA and FBI.
Naturally, attempting to discover exactly what the CIA and FBI were using Nagra products for during the 1950s and 60s in the United States is a task akin to acquiring a certain billionaire’s client list today.
These are some of the most highly guarded secrets in the modern world. One can indulge in flights of conspiracy if they seek some kind of answer, and those conspiracies are indeed entertaining, but one thing becomes clear when looking at what we know for certain to be true.
Two of the largest, most well-funded and powerful intelligence agencies in the world trusted The Nagra III to serve them as an audio recording device.
One could lose entire days imagining what conversations were recorded using The Nagra III- how much it might have influenced the modern world. Regardless, it is a testament to Nagra’s commitment to audio excellence.
The Future of Audio Excellence
2025 will mark sixty-eight years since The Nagra III’s release. The product has since been discontinued in favour of more advanced systems which utilise more modern technology, but its influence cannot be denied. Simply the fact that some of The Nagra IIIs are still functional is a reminder of the level of dedication that went into their design.
Nagra continues to innovate and tinker into the present, never once losing sight of that internal scientific process. Often, the term ‘precision engineering’ can be thrown around, particularly when it comes to audio equipment.
For that reason, we trust the reviews we seek out to give us that last bit of confirmation, and what better confirmation can one ask for than a silent nod of approval from the feds?
