Analysing Decompressed Audio with the "Inverse Decoder" - Towards an Operative Algorithm
Perceptual audio coding of high quality audio signals is nowadays widely used. To reproduce the audio data, the bitstream is expanded into an uncompressed audio format by the decoding algorithm. As shown previously, it is feasible to recover the encoding compression parameters from the decoded audio signal and even translate a decoded audio signal back into its original bitstream representation. This technique is referred to as "inverse decoding" and has several interesting applications, including tandem-resistant re-encoding of audio signals. The paper illustrates practical results obtained by the first working implementation of an "Inverse Decoder" based on the popular MP3 coder. The performance of the algorithm is evaluated in terms of reconstruction precision and computational complexity. Finally, algorithmic issues are discussed.
