What are online mastering services?

Online mastering services let artists worldwide send their mixed tracks to a professional mastering engineer remotely and receive release-ready masters back. At Razik Mastering, every track is processed by a real human engineer using analog hardware and high-precision digital tools — no AI and no presets — then delivered as a polished WAV optimized for streaming and all playback systems.

How does your online mastering process work?

Upload your full mix through our secure panel. You first receive a free mastered sample so you can hear the difference. Once approved, your track is fully mastered by ear, shaped to your genre, and delivered as a release-ready master in 24 to 48 hours with revisions included.

Is online mastering as good as attending a studio in person?

Yes. The same engineer, analog hardware, and process are used whether you attend in person or send your tracks online. Clients in the Washington, DC area are welcome to attend sessions, while artists worldwide receive identical quality through online delivery.

Do you use AI or presets for online mastering?

No. Every master is made by a real professional engineer who listens to your track and makes genre-specific decisions. No AI, no presets, no automated chains — just analog warmth, digital precision, and human judgment.

How fast is your online mastering turnaround?

Standard online mastering is typically delivered within 24 to 48 hours. Stem mastering projects may require additional time depending on complexity.

What file formats and settings should I send?

Send full mix files as WAV, AIFF, or FLAC at 16-bit or 24-bit — no MP3. Leave headroom on the master bus (peak around -6 dBFS, no limiter or clipping) so the engineer has room to shape the master.

Do you offer online mastering worldwide?

Yes. We work with artists, producers, and labels worldwide who are releasing music to streaming platforms and record labels. All masters are delivered online with transparent pricing and fast turnaround.

What's Included with Your Mastering

Every track is mastered by hand by a professional audio engineer — never run through an automated algorithm or AI preset.

Secure Payments

We accept PayPal, Credit Card, and Bank Transfer.

AI mastering tools process every track through the same automated algorithm. Our free sample is handled by a real human mastering engineer using premium analog hardware — every decision is made by trained ears, not a preset.

You'll receive a free 1 to 2 minute mastering preview — long enough to hear exactly how your song responds to professional analog mastering across the intro, main section, and drop or chorus.

No — we do not accept MP3 files. Please submit a WAV, AIFF, or FLAC file at 16-bit or 24-bit.

Yes. Same analog hardware, same engineer, same process. The only difference is length — you receive a 1 to 2 minute preview rather than the complete track.

The free mastering sample is available for one track per new client. If you have an EP or album, contact us after receiving your sample — we offer bundle pricing for multiple tracks.

Professional mastering enhances tonal balance, controls dynamics, increases loudness to competitive streaming levels, widens the stereo image, and ensures the track translates across all playback systems — from earbuds to club PA systems.

Most free mastering samples are delivered within 24 hours. If you have a deadline, mention it in your submission notes and we will do our best to prioritize your track.
