FAQs

Why isn’t my CD as loud as theirs?

We’ve all noticed that some CD’s are louder than others. That’s because, in most cases, the louder CD has been heavily compressed and limited. Compression makes a soft sound loud and a loud sound soft, while Limiting is a severe form of compression using much higher ratios and a “brick wall” that prevents the signal from reaching digital zero. Although dynamics processing allows the entire mix to be brought up by several decibels, if not done well, the reduction in dynamic range can be quite noticeable. Still, when done well, compression/limiting should not be a problem.

The DDP (Disc Description Protocol) image that is created in a mastering session is used as the master for mass replication. There are several formats that can be sent, including CD-R, DAT, and 1630. Most replicators today prefer DDP images; whereas DAT, an outdated technology, has fallen out of favor.
