Vinyl records need to be stored in an upright position to ensure they stay in good condition. Records that have been stored at a slant for an extended period of time can warp because of the uneven pressure that has been placed on them. This is why records are often kept in crates that position them upright.

Crackles - Coarse (Rales) Sounds Coarse crackles are discontinuous, brief, popping lung sounds. Compared to fine crackles they are louder, lower in pitch and last longer. They have also been described as a bubbling sound. You can simulate this sound by rolling strands of hair between your fingers near your ear.

Dropouts may be caused by a disk drive that cannot keep up with the recording. ... When this setting is "on" (default setting) Audacity will detect dropouts (brief gaps in the recording) and will insert zeroes into the recording to keep the other good parts synchronized.

CDs have a wide dynamic range. ... In some cases, the music might not be mastered to use all the dynamic range. But more modern recordings use technology to optimise how much audio energy can be squeezed into the available dynamic range. The resulting music sounds punchier and brighter, making it seem louder.

Picture discs divide opinion among vinyl circles. Some love them, and some hate them. Universally, however, most agree that sonically they don't sound quite as good as standard vinyl records. Some will go as far as to say they sound bad, but that can often be a little unfair.

CDs just sound better. ... Yes, vinyl has that “analog warmth,” but CDs don't crackle and pop, they don't skip, they have a much wider dynamic range so they can get louder than vinyl and they can get much quieter than vinyl.
