CDP Mastering is an online automated audio mastering service, based on an intelligent mastering system developed by Crazy Daisy Productions since 2001. Users upload songs through the website, choose a sound style and a few fine-tuning options, and the system automatically completes the mastering process. The company clearly states that this is a mastering service: it does not provide mixing, and it is not a replacement for an experienced human mastering engineer.
Its main strengths are speed and automation. A typical song usually takes around 2–4 minutes to process. Each song can be mastered in 2 different styles for free, and the system also offers detailed adjustments for loudness and dynamics, low frequencies, high frequencies, and more. It supports WAV, AIF, MP3, M4A, and WMA uploads. For each style, the final output includes 24-bit WAV, 16-bit/44.1kHz WAV, and MP3 files, making it suitable for release, broadcast, duplication, or previewing. As for limits, tracks must be at least 10 seconds long and up to about 5 minutes 30 seconds, with a maximum file size of 90MB.
Pricing is very straightforward: $5 for a single song, and $3 for each additional track in the same batch, with no subscription required. Payments are handled via PayPal, using either a PayPal account or a guest credit/debit card. The page does not appear to provide fuller terms on ownership of users’ music rights, retention periods for uploaded files, refund policies, and similar details, so it is worth checking the privacy policy and terms of service before using it for formal commercial projects.
The advantages are its low price, fast turnaround, no subscription requirement, and the ability to test the results with free samples first. Getting two styles and three formats for each song also lowers the cost of experimentation. The downsides are that automated mastering cannot handle custom needs such as fade-ins and fade-outs, mutes, edits, or special sound effects, and it cannot compensate for a poorly mixed track. Production workflow features such as collaboration, comments/annotations, and team management are also not apparent.
It is suitable for independent musicians, producers, bands, and creators who need to quickly improve the loudness and tonal balance of a demo or release version. For important commercial releases, award submissions, or album projects that require aesthetic judgment, a human mastering engineer is still the better option. The provided text does not indicate how well it can be accessed from China, so this remains unknown. Since payment depends on PayPal, users in mainland China may run into payment convenience issues. Alternatives worth considering include LANDR, eMastered, BandLab Mastering, CloudBounce, and iZotope Ozone.
