Audio disc Transfer


During the early years of audio recording, 78 rpm records were a popular medium for families to record and preserve valued memories. Voice letters 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 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.

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. On playback using modern technology, the sound increases linearly in speed as the disc reproduced, so finding the exact pitch for an accurate restoration is a challenge. Now, with modern technology, we can look at hidden frequencies in the recorded audio and use the constants to establish a benchmark for speed control.

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 surface of the disc 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 adds artifacts like wow and flutter.

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

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 the help of tailored software, we correct the playback speed of the transferred digital file. Additional noise and distortion removal services are available to remove or reduce background noise that may be distracting to the listener. Your original Audograph recordings will be returned to you as a CD, digital files, or hard drive/thumb drives.
