The RIAA Curve

The RIAA Curve is a standardized way the Recording Industry Association of America (RIAA) equalized audio recordings, especially vinyl records, to improve sound quality during playback. It involves boosting bass frequencies and reducing treble during recording, then reversing these adjustments during playback. This process reduces noise, prevents low-frequency distortion, and preserves record cleanliness. Essentially, it's a method to ensure consistent sound quality and longevity of records, making music sound balanced and clear when listened to on compatible equipment.
