Smartphone based real time classification of noise signals using subband features and random forest classifier
This paper presents the real time implementation and field testing of an app running on smartphones for classifying noise signals involving subband features and a random forest classifier. This app is compared to a previously developed app utilizing mel frequency cepstral coefficients features and a Gaussian mixture model classifier. The real time implementation has been carried out on both the Android and iOS smartphones. The field testing results indicate the superiority of this newly developed app over the previously developed app in terms of classification rates.
