Testing, Testing: A Collage of Hi-Fi Test Recordings

In this episode, we pay tribute to high fidelity test recordings for record players and tape players.

Stereo test recordings were not only abundant from the late 1950s through the early 1970s, they were a necessity of the hi fi industry that wanted to convince the consumer to trade-in their monophonic gear for a stereo player. Some of these recordings were highly technical and provided detailed instructions for putting one’s stereo through some extraordinary audio paces that only a true audiophile could appreciate, let alone afford. There emerged an alternative kind of test record for everyone else, a kind that featured music and sound effects to dazzle one with the stereo separation provided by two speakers. This episode is comprised of excerpts from eighteen test recordings from the Archive spanning the years 1955 to 1980. Two of these are actually tests for tape machines, one for a reel-to-reel player and one for a cassette player.

I have roughly organized this audio experiment into three parts: the first comprises introductions and spoken word guidance for the records, with added audio effects and treatments; the second part mixes several tracks without any audio manipulation other than editing; and the third and final part explores the special effects and music that were often included on these discs, again with my audio treatments.
