CD Mastering
Masters prepared for CD-compatible delivery, including appropriate final files and sequencing requirements where supplied as part of the project.
The starting point is always the mix and the release goal. SPL Mastering does not apply one preset chain to every record; the processing route is selected according to what the track needs to translate and feel finished.
Reference pricing
Mastering + £10 CD master
Final pricing can vary with project scope, stem count, number of tracks, alternate versions or specialist delivery requirements.
What is included in the mastering workflow?
Mastering decisions
EQ, dynamics, stereo, saturation and level are used only where they improve the record and support the intended playback environment.
Release delivery
Approved masters are supplied in the formats agreed for the project, with secure communication and delivery available through XYPHERON.Chat.
London / M25
Available across the full service area
CD Mastering is available to clients throughout London and the M25 through the same remote-first approval workflow. West London clients can also discuss attended requirements where appropriate.
CD Mastering FAQs
What should I send before mastering?
Send the final approved mix at its native sample rate and bit depth, avoiding clipping. Include references and tell SPL where the record is going: streaming, club, radio, CD, label catalogue or multiple destinations.
Can you tell me if the mix needs changes first?
Yes. If something in the mix is likely to prevent a strong master, feedback can be given before committing to unnecessary processing.
How are revisions handled?
Review the master on playback systems you trust and send focused notes. Project communication and delivery can be kept together through XYPHERON.Chat.
