Audio disc Transfer

Audio Disc Transfer Service

Creative Audio Works provides quality disc transfer, Gray Audograph discs, SoundScriber discs, 78 RPM discs, and many other disc formats from the past.

During the early years of audio recording, 78 rpm records were a popular medium for families to record and preserve valued memories. Voice letters were popularized as World War II progressed in the 1940s. Service members could record messages at a local United Service Organization (USO) club and send them home to loved ones. Some of the most famous classical and jazz musicians of the 1920s through today were and are still recorded on 10 and 12-inch vinyl records. Throughout history, we’ve innovated recording technology to preserve the most critical moments.

Creative Audio Works archiving and mastering studio transfer studio can transfer all types of discs, from 16 rpm through 78-rpm records, and monitors every disc in “real-time” for optimum tracking and overall quality.

Archival quality phono pre-amps made especially for audio restoration work give us the versatility to dial into almost all the equalization curves used from the early nineteen-hundreds through modern-day recordings.

The Audograph Disc

Audograph discs are a unique “dead” media to transfer and restore. Introduced in 1945, the Audograph Disc designed as a portable dictation system. During playback using contemporary technology, the pitch increases linearly in speed as the disc reproduced, so finding the exact pitch for an accurate restoration is a challenge. With modern technology, we can look at hidden frequencies in the recorded audio and use the constants to establish a speed control benchmark.

Audograph Disc

The Gray Audograph disc groove was embossed into a soft plastic disc by a recording device. Discs were only compatible with Audograph recorders. The sound was recorded from the inside of the disc to the outside.

The Audograph is a Constant Linear Velocity (CLV) disc. In other words, one second of audio requires a set groove travel distance at the beginning of the recording and the same amount of travel at the end of the recording. This design allowed more information to be recorded on a small disc.

Rather than a conventional constant-speed spindle drive, mechanical rollers mounted close to the cutting head are responsible for driving the disc’s surface as the cutting head travels. For reference, a conventional turntable would record that same set amount of groove travel distance at the beginning and maybe half that amount at the end of the recording. With the Audograph, the turntable platter speed continually changes from the beginning to the end of the recording as the circumference increases. As a result, the groove travel distance per second is constant. The unique mechanical aspects of this obscure audio format also add artifacts like wow and flutter.

Since there seem to be no published specifications regarding the Gray Audograph recorder, we have to decide based on the transferred files themselves.

SoundScriber Discs

Dictation recording

SoundScriber is a dictation machine introduced in 1945 by The SoundScriber Corp. It records sound with a groove embossed into soft vinyl discs with a stylus. The machine can record 15 minutes of dictation on each side of a thin (.01-inch) flexible 6-inch vinyl disc spinning at a rate of 33 1⁄3 RPM.



Our Process

As standard procedure, all records will are cleaned before transfer. Once cleaned, we transfer each disc onto a modern turntable using a moving coil cartridge with a custom stylus and a state-of-art phono preamp.

After initial transfer and with tailored software, we correct the transferred digital file’s playback speed. Additional noise and distortion removal services are available to remove or reduce background noise that may distract the listener. Your original record or disc Audograph recordings will be returned to you as a CD, digital files, or hard drive/thumb drive.
