The aim of this work is to analyse the performance of Apple's iPhone and iPad as voice recorders, while at the same time finding algorithms to enhance speech recordings and reduce the noise introduced by the low quality built-in microphone. We perform spectral analysis of silent recordings to acquire the noise print from different device models and propose a MATLAB implementation of a noise reduction filter

Abstract
The aim of this work is to analyse the performance of Apple's iPhone and iPad as voice recorders, while at the same time finding algorithms to enhance speech recordings and reduce the noise introduced by the low quality built-in microphone. We perform spectral analysis of silent recordings to acquire the noise print from different device models and propose a MATLAB implementation of a noise reduction filterFile in questo prodotto:
