Online mixing and mastering

Radio-ready records, mixed and mastered in one room.

I mix and master your song myself, in my Los Angeles studio — through the same analog chain and monitoring used on major-label releases. Three revision rounds as standard, and unlimited revisions free for first-time clients with the code FIRSTMIX.

What you get

Everything a finished record needs.

One price, one engineer, no add-ons bolted on at checkout.

Professional mixing

A full mix by me, using the same analog gear and plugins used on major-label releases — balance, EQ, compression, effects, the lot.

Vocal tuning & alignment

Precise pitch correction and every take aligned so the vocal sits where it should. Auto-Tune on the Pro package; Melodyne and Auto-Tune on Elite.

Drum replacement when it’s needed

Professional samples blended with your original tracks for punch and clarity, without losing the feel of the performance.

Analog mastering

The final master runs through real analog mastering hardware for warmth, punch and the finish you hear on the radio.

Revisions until it’s right

I work with you until you’re happy. First-time clients get unlimited revisions free — no pressure, no hidden fees.

The room

Where your song actually gets made.

Not a bedroom, not a laptop in a coffee shop. This is the room your record passes through, and the hardware it passes through in it.

Analog front end

Avalon 747 vacuum-tube compressor and EQ · Locomotive Audio 14B tube limiter · Black Lion Audio BLUEY FET limiting amplifier.

Mastering chain

Bettermaker Mastering Limiter, Mastering Compressor and Mastering Equalizer — recallable analog processing, so a master can be revisited exactly as it was.

Conversion and monitoring

Lynx Aurora(n) conversion · RME ADI-2/4 Pro SE · Trinnov D-Mon monitor control · Kii Three active monitors.

Plugins

A full professional plugin library alongside the hardware. The analog chain is what most rooms don’t have; the plugins are simply the rest of the toolkit.

Why one engineer

Why every mix here includes mastering.

Most online mixing services send back a mix file and call it done. Here’s why that shortchanges your record.

The problem with mixing only

  • An unmastered mix sounds unfinished. It lacks loudness, low-end tightness and the high-frequency air mastering adds.
  • Spotify, Apple Music and Tidal all normalise loudness. Without mastering, your song arrives quieter and smaller than everything around it.
  • Mix and master decisions are connected. When two engineers work in silos, things fall through the cracks.
  • A great mix engineer hears your song differently than you do. They hear the 808 fighting the kick, the vocal getting swallowed in the chorus, the hi-hats poking too hard at 2:14 — and then they fix all of it.

The advantage of one engineer for both

  • I mix with the master in mind. The low-end decisions I make while mixing already account for what the mastering limiter will do.
  • Your song goes out finished — ready for Spotify, Apple Music, vinyl, radio and sync the moment you receive it.
  • Yes, major labels separate mix and master. They also have dedicated teams, months of time and six-figure budgets.

Pricing

Two options, but the same mix.

Both options include mixing and analog mastering. The quality is the same — the difference is in the details.
