What We Do

Full-service mixing & mastering

From a single vocal stem to a full album, every project is mixed on calibrated monitors and mastered for the platforms your fans actually use.

From $150 / song

Mastering

Loudness-calibrated stereo mastering optimized for Spotify, Apple Music, and club systems, with a vinyl-safe option.

From $60 / song

Vocal Production

Pitch correction, comping, ad-lib arrangement, and harmony stacking to get a lead vocal performance-ready.

From $80 / song

Stem Mastering

Why Sidechain

An engineer who mixes for the room your fans are actually in.

Naomi Chen started Sidechain Audio in 2017 after years mixing on the Atlanta studio circuit, working sessions for independent rappers, R&B vocalists, and gospel choirs across the city. The studio was built around one idea: a mix should translate — car speakers, AirPods, and the club system — not just the room it was mixed in.

Every project gets reference checks across multiple playback systems before it's delivered, and every client gets two free revision rounds built into the price.

Translation-first mixingChecked on studio monitors, consumer earbuds, and car audio before delivery.

Hybrid analog/digital chainVintage outboard gear for warmth, modern plugins for precision and speed.

Fast, honest turnaroundMost mixes returned in 48–72 hours with clear, itemized pricing up front.
