Audio Noise Reduction Using Low Pass FiltersDOI: 10.4236/oalib.1103709, PP. 1-7 Subject Areas: Applications of Communication Systems, Artificial Intelligence Keywords: Low Pass Filters, Noise, Audio Filtering, IIR Filters, FIR Filters Abstract
The study aimed to filter and remove noise from
audio, and in this study researcher followed the descriptive
analytical method. The study sample consisted of an audio file and has been
save Audio of on a formula (WAV), and the study used matlab 7.10.0 to read
sound and design low pass filter, then insert the audio signal with the noise
signal into the filter and output a signal audio without noise. The researcher
has reached findings that differed according to
the rank of the filter. The low pass filter has a great effect on
removing noise during the registration process together with the times of
implementation.
