Audio and Speech Processing. Collection of Articles usefull in Audio and Speech Processing. Tuesday, October 03, 2006. Using Sox as a library to read audio File. Ok so finally I decided to test what I have been studying in audio processing and use it with C/C searched the web and finally figured out sox is pretty cool. It already has code to take care of most file operations. Cool I thought lets try to reuse some of the source files - tried and failed - ran into compiler and linker error :-(. Libsta(vorb...

Sound intensity is frequently expressed in terms of decibels (dB). The decibel (1/10 of a Bel) was named in honour of Alexander Graham Bell. It expresses the logarithm to the base 10 of. The ratio between two sound intensities or (sound pressures). Internationally recognised reference standard intensity for sound is 10.
