One Fact That Changes Everything

National Audio Company is the last manufacturer of music-quality recording tape for cassettes on earth. Not just in America. The entire world. With 57 years of refinement and reinvention under our belts, we practice our craft in Springfield, Missouri—right in the heart of the American Midwest. And from here, we support analog music fans across the planet.

Committed to Cassettes

Who still makes cassette tape? National Audio Company.  While others chased trends, NAC doubled down on cassettes. In total, we’ve spent 57 years serving the industry, with the past 10 focused on manufacturing recording tape for cassettes. During that time, we’ve gathered a team of experts and engineers whose knowledge is unsurpassed.  "Staying wasn't just loyalty,” explained NAC President Steve Stepp. “It was expertise compounding over decades." To understand National Audio Company’s importance to the music industry, we have to go back to our founding. When we started in 1969, we worked with radio stations and recording studios, taking care of their reel-to-reel tape needs.  In 1980, we began loading cassettes with Ampex tape here at our Springfield, Missouri plant. For the next few decades, we carved out a niche serving the audio needs of a variety of businesses, including:

• Books on Tape for libraries and schools
• National Library Service (Division of the Library of Congress)
• Audiobooks and magazines for the blind and visually handicapped
• Blank tapes for court recorders

In the early 2010s, artists were intentionally keeping tape alive when and where they could. When Pearl Jam released “Vs.” and “Vitalogy” together in 2011, the 20th anniversary box set included a special cassette featuring their legendary January 8, 1995 Self-Pollution Radio broadcast.

In both cases, sourcing the cassettes was a bit of a challenge for their labels. At the time, there just weren’t many places to get high-quality cassettes made. National Audio stepped in to fill the gap, helping set the stage for a cassette renaissance. At the same time, we became a key resource for independent musicians who wanted an affordable option to get their music out there. As demand for high-quality cassettes increased, our production expanded to keep pace. By the mid-2010s, we had begun the process of formulating and manufacturing our own recording tape in-house.  This was a critical juncture for NAC. “It was 20 years ago that the major players decided to get out of analog music with their eyes on the digital future,” Steve explained. But where others jumped ship, National Audio stayed the course. “We doubled down on analog and started manufacturing our own tape in 2016, and it wasn’t long before the biggest names in the business came to us to make their cassettes.”

Trusted with the Irreplaceable

Today, most major record labels entrust NAC with their master recordings. These unique recordings are then turned into “duplication masters” by National Audio.  What is a duplication master? When a musician records an album in-studio with a record label we work with, they send us the original recording. From this, NAC creates a duplication master—the master recording from which all authorized copies are made.  It is the physical manifestation of the artist’s work, as recorded in-studio on cutting-edge equipment. And once NAC gets it, we optimize it for the analog format. Each duplication master is securely stored in NAC’s archive, which currently houses more than 80,000 titles! NAC’s archive is a treasure trove of music. We’re proud to safeguard master recordings from Pearl Jam, Smashing Pumpkins, and many more.  These are not just recordings; they are irreplaceable pieces of music history.

When the biggest names in the industry call, NAC answers. As President Steve Stepp likes to say, “If it’s important enough for you to call, it’s important enough for us to answer.” It’s that kind of personal service that’s kept NAC flourishing.

One Roof, Many Formats

As one of the last cassette tape manufacturers of music-quality recording tape, we’re committed to cassettes. We specialize in cassette tape manufacturing and cassette tape duplication.  But our technical expertise and appreciation for music mean we also enjoy producing top-quality audio in other formats, from vinyl record pressing to CD duplication. NAC offers one-stop music production for big music labels and independent artists alike. Our comprehensive capability has several benefits: 

• Top-quality audio on many formats
• Simpler process for customers
• Made in America for better communication and supply chain control

We also offer audio engineering and analog-to-digital transfer services. National Audio can transfer open-reel tapes of all speeds and tape widths, audio cassettes, vinyl, and most other common audio formats. We can help recover valuable audio recordings from open-reel tapes, even ones that have become “sticky” with age.

National Audio Company has been entrusted by governmental, commercial, and institutional clients to transfer thousands of irreplaceable analog recordings. We can also transfer special media to digital formats:

• Radio programs
• Music and instructional libraries
• Old master recordings

Quiet Confidence

National Audio Company doesn't need to turn it up to 11. The facts speak loudly and clearly: 

• 57 years in business 
• The trust of major labels worldwide
• The last manufacturer of music-quality cassette tape in the U.S.

We're not just preserving a format; we're preserving an art form. And we’re just getting started. Stay tuned—you'll be hearing more from NAC.

We're National Audio Company, and we've been devoted to true sound reproduction since 1969. Known as “The Great American Cassette Company”, we’re the only music-quality cassette tape manufacturer in the world. In an era dominated by streaming and digital downloads, how does NAC not only survive, but thrive? The answer lies in our commitment to professional-grade audio fidelity, music preservation, and expert knowledge of what makes magnetic tape recording special.

Our Journey from Distribution to Manufacturing Excellence

Our story began over five decades ago in Springfield, Missouri, where we started as a distributor of professional recording equipment. For 12 years, we built our reputation distributing Ampex recording tapes and Fidelipac broadcast cartridges to radio stations, studios, and audio professionals across the country. We learned the business inside and out, understanding what audiophiles, broadcasters, and musicians needed from their magnetic media. In 1980, we took a pivotal step: we began manufacturing audio cassettes using Ampex tape. This wasn't just a business decision; it was a commitment to quality control and innovation. We wanted to produce blank cassette tapes that met the exacting standards we'd come to appreciate through years of working with professional audio equipment. By the late 1980s, our "Audio Pro" cassettes had become the industry standard for cassette duplication. The secret? Precision manufacturing, carefully formulated tape coatings, and quality control protocols that ensured consistent frequency response and signal-to-noise ratios across every single cassette we produced.

Growing When Others Were Shrinking

As demand for our professional-quality cassettes grew, we expanded twice—relocating to a 28,000-square-foot facility in 1989, then moving to our current 135,000-square-foot factory in 1998. While our competitors were eyeing the CD revolution, we were doubling down on cassette manufacturing excellence.

The early 2000s brought massive industry shifts and major cassette duplicators pivoted entirely to CD production. We saw something different. We recognized that cassettes still served vital roles in educational materials, religious programming, audiobooks, and increasingly, among music enthusiasts who appreciated analog sound quality.  Rather than abandon the format, we expanded our cassette duplication services. As competitors chose other avenues, we acquired their equipment, restored and upgraded it, mastered its use, and retrofitted an entire floor of our historic building to produce top-quality magnetic tape.  Today, National Audio Company offers three types of tape purpose-built for different recording needs:

• FerroMaster C256™ - the classic ferric cassette tape you know and love. It is refined for use in consumer cassette decks for high-quality recording and playback. 
• FerroMaster C456™ - the highest quality ferric cassette tape available in the world today. This product has been tested in high-speed duplication equipment and delivers outstanding quality. 
• FerroMaster C756™ - This Cobalt oxide Type II High Bias tape is made for the most demanding recording applications and is the gold standard in Type II performance. 

We are also refining and enhancing our Magne-Sheen tape coating and finishing process. This will allow smoother contact with recording and playback heads, along with superior audio performance.  Learn more about NAC’s cassette manufacturing capabilities 

The Science of Superior Sound

What makes a music-quality cassette tape superior? It comes down to physics and chemistry working in perfect harmony. Our Type I ferric oxide formulation delivers excellent high-frequency response while maintaining low noise floor characteristics essential for music reproduction. The tape coating must be applied uniformly to within microns of tolerance—inconsistencies create audible artifacts called dropouts and alter frequency response curves. We've refined our coating process to achieve remarkable consistency. The cassette shell itself matters tremendously. Poor shell design creates mechanical friction, uneven tape tension, and wow-and-flutter variations that degrade audio quality. Our cassette shells are precision-molded with tight tolerances, ensuring smooth tape transport and optimal head contact throughout the entire playback duration.

We also understand cassette tape longevity. Properly manufactured and stored cassettes can preserve audio fidelity for decades because magnetic tape is inherently stable. Unlike optical media that can delaminate or digital files dependent on functioning storage devices, quality cassette tape is remarkably archival.

Global Reach Through Strategic Partnerships

We're proud to be America's cassette manufacturer…and now, our reach extends globally.

The Analog Renaissance

Today, we're experiencing something remarkable: musicians and music fans are rediscovering cassettes. For Gen X, it’s the memory of making (or getting) that first mixtape. For Millennials and Gen Z, it's discovering what their parents knew—that cassettes offer something streaming can't. 

They're drawn to the warmth of analog sound, the tactile experience of holding real music in your hands. It's about audio character, about the subtle tape saturation that adds richness to recordings, about the ritual of physical media. If that sounds right to you, you need to know about us. Like cassettes themselves, National Audio Company is here for the long haul and our tape is still rolling! Stay tuned—you’ll be hearing more from NAC.
