A vinyl record that is even slightly warped or has a hole that.
High pitch noise vinyl.
I am interested in vinyl and i am certainly planning on upgrading my turntable but i am financially not in the position to do so right now so i want to try and work with what i have.
Both extremes cause hiss and surface noise to increase.
Sometimes is can sound like a buzz or a very high pitched whistle.
There is one more quality control issue that plagues the record making process.
Vinyl depends on a mechanically driven system and any such system will introduce minute changes in the speed and pitch of playback.
When playing records on my turntable they play at a considerably higher pitch than the original recording.
