![]() However, unlike 78 RPM records, 33 1/3 didn’t have a smooth start. Like almost all of the record players available, your record player also most probably has a standard RPM of 33 1/3. 33 1/3 RPMģ3 1/3 became the standard speed that most of the records offer. These days, 78 RPM records are not in production and many records player doesn’t even provide this speed option anymore. These records were found to be more brittle and prone to shattering. However, in addition to shorter playback time, other various shortcomings accompanied 78 RPM records. The sizes vary, but in general, the 10-inch size started becoming the standard size for 78 RPM records. Following her, many audio manufacturers produced record players similarly – the players were 3600 RPM electric motor driven, making 78 RPM the standard record speed by 1925. But on the downside, when the RPM of a record increases, the playback time it offers decreases.Įmile Burner, in 1888, created records that were played between 70 and 80 speeds. Records offer the best sound quality when turned at a higher RPM. Let’s discuss vinyl record speeds in detail. At a certain point in history, 8 1/3 RPM and 16 2/3 RPM were also in use. ![]() There are primarily three vinyl record speeds 33 1/3, 45, and 78 RPM. One might hear the sound slower or faster instead of melodious record songs if the RPM is not adjusted accordingly on the record player. RPM means revolution per minute, i.e., the number of times the record rotates on the turntable in a minute.
