Abstract
A digital recording system for stereophonic audio signals is disclosed. Included is an MP3 encoder coupled to an ADC for encoding the two channels of digital audio signals into a compressed data stream. Before being directed into a flash memory for editing, the compressed data stream is split into the original two channels of audio data blocks. An editing device is coupled to the flash memory for block-by-block editing of the stored audio data blocks. On being subsequently retrieved from the flash memory, the two channels of audio data blocks are reformatted into an MP3 data stream preparatory to introduction into an MP3 decoder.
