Paper Review

This was a group Experiment - finding out relevant papers and patents on DSPP applications. We, as a group of 5 - Abhijit Haridas, Shreyas Padte, Vipan Koul, Sakshi Joshi and myself had to study on research papers and patents which implemented compression of the audio signal. We chose to study "Audio Compression" as an application.
Paper Review
Paper: International Journal of Computer Applications (0975 – 8887)                                                                 Volume 86 – No 13, January 2014                                         
Summary:
Audio compression has been carried out by various methods such as Discrete Cosine Transform, Wavelet Transform, Wavelet Packet Transform (W.P.T) & Cosine Packet Transform. Mean compression ratio has been calculated for each of above methods. Various other parameters have been calculated and compared. Output for each transformation was observed and it was found that Wavelet Packet Transform gives the best compression ratio as compared to other methods.

  1. Speech compression is an important practice so that less storage space is required and also less energy and transmission power is utilized during transmission.
