ABSTRACT:
A transforming apparatus for compressing digital audio signals of a first format for transformation into second digital audio signals of a different format or a second format. The transforming apparatus includes a peak level calculating circuit for calculating the audio level of the digital audio signals of the first format, a hard disc unit for recording and reproducing level data of the digital audio signals of the first format along with the second digital audio signals to which data exclusively used for the second format are appended and a level indicator for displaying the audio level of the digital audio signals of the first format prior to transformation for monitoring the level of the pre-compression digital audio signals.
