主　　题：Digital signal processing Wavelet Programming language Performance analysis 

摘      要：The time spent processing the test set is a crucial factor in research projects involving audio signal transforms. The present work analyzes the performance of a set of programming languages commonly used in this type of scientific research. The results showed the C and C++ languages as faster in a test suite with 8 different programming languages implementing the discrete Wavelet transform.
