Regenerator
The DAISY Regenerator upgrades DAISY 2.0 books and corrects some problems in 2.02 books, producing valid DAISY 2.02 output by refreshing, fixing and updating the content of the DTB files so that they comply with the 2.02 specification.
RMS Level
The average energy level of the recording. Even if the peak level is close to 0 dBFS, the apparent loudness or amplitude of the recording can seem low. In this case, RMS levels are too low and could be improved by increasing the signal input level and using a peak limiter to prevent digital distortion and clipping.
