Keller's invention of a "moving-coil" playback stylus made possible the first hi-fi records. In 1931-32 Keller made the first known stereophonic and high-fidelity recordings of orchestral music. On April 19, 1938 Keller was issued US patent number 2,114,471 for his idea of recording the two channels of a stereo recording in one record groove each at 45 degrees from vertical.
Keller was awarded the Gold Medal from the Audio Engineering Society in 1981 for outstanding developments in stereophonic disk recording. He was a Fellow of the Acoustical Society of America and the Institute of Electrical and Electronics Engineers, and a member of the American Physical Society and the Yale Engineering Association.
