Why are some LPS 45 rpm?

In order to make the disc smaller than the 10-inch, 78-rpm discs used since the 1890s, they reduced the speed to 45-rpm and used a much finer groove. This meant that they could pack in more grooves in a smaller space.

Why do singles play at 45rpm?

7-inch format The 7-inch 45 rpm record was released 31 March 1949, by RCA Victor as a smaller, more durable and higher-fidelity replacement for the 78 rpm shellac discs. To compete with Columbia, RCA released albums as boxes of 45 rpm 7-inch singles that could be played continuously like an LP on their record changer.

Is 45 rpm higher quality than 33?

Since 45s travel faster than 33s, more waveform definition can be squeezed into the format, which takes up more room. More bumps and grooves created in pressing a 45 means better audio quality. Again, it is similar to MP3 sound quality issues in the digital world.

What RPM do LPS run at?

331⁄3 rpm
The LP (from “long playing” or “long play”) is an analog sound storage medium, a phonograph record format characterized by: a speed of 331⁄3 rpm; a 12- or 10-inch (30- or 25-cm) diameter; use of the “microgroove” groove specification; and a vinyl (a copolymer of vinyl chloride acetate) composition disk.

Why are some records 33 and some 45?

Beta to Blu-ray vs HD-DVD, companies have often put out competing formats. RCA, which failed miserably in the 1930s to release a 33 to the public went out to release a 45 RPM. The record was smaller than the other options. Ultimately, RCA released the format in order to directly compete with the Columbia Record 33.

Why do LPS sound better?

Because of their materiality, records offer sound qualities that digital formats do not. These include warmth, richness, and depth. Many people value those qualities and so hold vinyl records to sound better than digital formats.

Why do different records have different speeds?

Record players have these different speeds because records were designed to be played at different speeds. You want to make sure to have your player at the correct speed otherwise the record will sound “off” and will either be higher pitched and faster than it should be or sound deeper and slower than it should.
