In 1931 rca victor introduced the first 33 rpm records and players but they were a commercial failure.
Why different rpm vinyl.
Additionally longer wavelengths smaller angles in the grooves and the less complicated geometry at 45 rpm help to cut very precise grooves with very fine detail.
The higher the rpm the greater the length of vinyl picked up by the stylus and ultimately the more accurate our sound reproduction becomes.
But the record manufacturers felt the fickle public then deserting the phonograph in favor of a newer novelty the radio would be put off by the cost of converting from 78 to 33 1 3.
Once vinyl took over for the next few decades all domestic record players had four speeds.
Vinyl records typically come in three speeds.
Most turntables can play 33s and 45s while 78s require a certain kind of stylus and motor speed.
But hollywood exerted its influence in a different way.
Jerry shafer has covered everything except the 16.
If you re like most record lovers you ve probably flipped speeds from time to time in order to hear your music faster or slower than normal.
As it turns out the height of the great depression was not the ideal time to launch an expensive novel consumer technology.
Anyone who s as old as this reporter will recall they had 78 4.
It s a funny little experiment but what are there three different speeds to begin with.
33 45 and 78 rpm represents the speed at which the record spins on your turntable.
33 45 and 78 rotations per minute rpm.
So let me complete that.
