Master your collection of songs so that it sounds like a cohesive CD rather than a jumble of songs with differing volume levels and tonal qualities. Equalization (EQ) adjustments and gentle use of effects such as reverb and compression can all make your CD sparkle. Mastering software is quite affordable offers many features, but it also requires a significant level of skills; unless you're accomplished in this area, consider sending your mixes out to a professional mastering facility. It may create an added expense, but if you going through the trouble and expense of creating a CD, don't cut corners in audio quality.
Research several online CD replication and duplication companies (see the link in the Resources section below) and request quotes from them. Some will charge extra for shipping; some will include it in the price, so pay attention to the fine print. Figure out your packaging requirements and how many copies you need in advance. Factors such as the number of panels you have in your CD inserts and how many colors you need on them will all affect the price.
Download artwork templates from your manufacturer of choice. Using these templates will ensure correct sizing and specifications, which will help you avoid unnecessary and costly delays. If your graphic design skills aren't up to par, hire a graphic artist to prepare your sleeve design. Your CD sleeve plays an integral part of your recording project; since it represents the music on the CD, it needs to look as professional as possible.
Upload your art and audio files to the manufacturer. Ask plenty of questions of your contact person at the company so you can minimize any technical glitches and mismatched file formats that could delay your order. Audio files are large, and uploading them can become extremely cumbersome; consider using a file transfer protocol (FTP) service to deliver the files.
Review the PDF proof of your CD artwork that the manufacturer sends you, and if all looks well, email the manufacturer with your approval. The company will now manufacture and package your CD with your artwork. The turnaround time varies between companies and will also depend on the type of shipping you choose. Whatever the time frame, use this time to plan your marketing strategy for selling your CD—by far the most challenging part of the process.
