Coefficient Audio is an audio post-production service for musicians, bands, DJs, and labels. Its core offerings cover mastering, Stem Mastering, final mixing, CD Master, DJ Mix/compilation processing, plus vinyl restoration and remastering. The website reads more like a service price list and delivery-specification guide than an online automated tool.
Its services focus on “release-ready audio delivery.” For digital releases, clients can receive 16bit/44.1kHz WAV files suitable for platforms such as SoundCloud, YouTube, iTunes, and Spotify, with 24bit WAV or 320kbps MP3 also available for free. For CD releases, it can deliver a DDPi file set or a physical Red Book/CD-A disc package. For vinyl releases, it takes into account cutting risks such as high frequencies, sibilance, and low-frequency phase issues, and delivers high-resolution 24bit or 32bit WAV files suitable for vinyl. For cassette releases, it typically provides 16bit WAV files according to the duplication service’s requirements.
Pricing is transparent: mastering costs £35 per track for 1-3 tracks, £32 per track for 4-8 tracks, and £28 per track for 9 or more tracks. CD Master is £30, DJ Mix or CD compilation processing is £65, Stereo Mix is £120 per track, Stem Mastering for up to 6 stems is £45 per track, and vinyl restoration/remastering is £75 per album. Returning artists and labels can receive single-track discounts, while larger projects can be quoted separately. Payment is by bank transfer or PayPal, with a clear “no upfront payment, pay when satisfied” policy.
The strengths are clear pricing, professional delivery formats, and coverage of multiple release scenarios including digital, CD, vinyl, and cassette. Its guidance on source-file standards, headroom, avoiding MP3, and related requirements is detailed, which helps improve final audio quality. It also promises revisions and archived backups of mastering sessions. The limitations are that the website does not specify turnaround time, copyright ownership, the exact equipment chain, listening samples, or an online collaboration system, making it better suited to projects that can communicate via email and file transfer in the early stages.
Coefficient Audio is suitable for independent musicians and labels that need human mastering judgment, release-format preparation, and multi-format compatibility handling, especially projects planning CD, vinyl, or cassette releases.
