Universal compressed audio player |
摘要 |
A universal compressed audio player having the ability to decode and play an encoded audio file residing in a music storage, regardless of the particular encoding algorithm used to encode the audio file, consists of: a music storage containing a compressed audio file to be decoded; a programmable digital signal processor adapted to decode the compressed audio file under the direction of a decoding software program; a nonvolatile memory containing the decoding software program directing the operation of the digital signal processor; a program adapted to copy the decoding software program from a memory card into the nonvolatile memory; a digital-to-analog converter to convert the decoded signal into an analog audio signal; and a speaker or headphones to convert the analog audio signal into sound.
