Why Audio Length Matters for Vinyl Quality

The amount of audio per side significantly impacts the fidelity of a vinyl record. This is due to several factors:

• Groove Spacing: Longer audio requires narrower grooves, which can limit dynamic range and bass response. Shorter sides allow for wider grooves, leading to louder, more dynamic, and punchier sound.
• Inner Groove Distortion (IGD): As the needle approaches the center of the record, the linear speed of the groove relative to the stylus decreases. This makes it harder for the stylus to accurately track high frequencies and loud passages, leading to distortion. Longer sides exacerbate this effect.
• Bass Frequencies: Low frequencies require more groove space. Excessive bass on a long side can cause the stylus to jump or the grooves to cut into each other.
• Loudness: A louder record requires wider grooves. If you want a loud master, you need less play time per side.

For optimal sound quality, it's generally recommended to stay well within the suggested maximum times, especially for albums with significant dynamics or bass content. Often, a 2xLP (double album) is chosen for full-length albums to ensure maximum fidelity per side.
