A complete program for sound quality restoration and enhancement
The following remedies can be taken when a mechanical feel to the vocals or missing frequencies in the accompaniment is noticed after separation:
- EQ CompensationVocal tracks are boosted by 2-3dB around 3kHz to enhance clarity, and the backing tracks use a 30-band equalizer to fill in the low frequencies below 80Hz.
- dynamic processing: Use a -4dB threshold, 3:1 ratio compressor for vocals with significant hiss, and add 1% reverb to the backing tracks to restore a sense of space.
- AI Repair ToolchainCombined use of Acon Digital Restoration Suite to remove spit + iZotope RX 10 De-hum to remove grid interference.
- phase correction: Check the vocal/backing phase relationship in your DAW, fine-tune the delay by 0.1-5ms to eliminate the offset phenomenon
Special note: For songs with complex harmonies, it is recommended to keep the original 5%-10% vocals mixed into the backing tracks to avoid the "hollowing out" effect. For professional production, Melodyne can be used for pitch correction.
