Zusammenfassung
We present an approach to estimate encoder parameters from previously MP3PRO-compressed, then decompressed audio material. The algorithm has been designed to identify the presence of spectral band replication (SBR), and for bit-rate detection. Furthermore, MP3 compression parameters like frame offset and block type are detected. As evaluation results show, the approach is able to identify SBR with a high accuracy, while the compression bit-rate detection is prone to errors, especially for higher bit-rates.
