I'm facing an issue while migrating my library from the deprecated scriptProcessor to AudioWorklet. Current implementation with ScriptProcessor It c ...
I have made a low-pass-filter for image analysis using 2-dimensional FFT. It simply consists of 3 steps, (1) FFT of an original image, (2) replace hig ...
I wrote a low-pass filter based around the FFT algorithm. First I process the input data using forward FFT, then I decrease the "volume" of parts of ...
I need to implement a lowpass filter in Python, but the only module I can use is numpy (not scipy). I tried using np.fft.fft() on the signal, then set ...
I have a signal 3M samples long. I want to subsample it. I know that to avoid aliasing I need to filter off frequencies higher than Nyquist frequency. ...
We are working on a project which allows us to record some sounds from a microphone with a 5k Hz sample rate with some Low-Pass filter & HighPass ...
I have noisy heading data for a vehicle that I would like to filter. However, the vehicle heading must be an angle between -180 and +180 degrees, so t ...
I'm trying to add a LowPass filter to an AudioTrack or MediaPlayer, but I don't think it exists. It seems that the Android Audio Framework, unlike th ...
When designing low/high/bandpass filters I encountered the problem that they do not work as expected (see code and output). I want to isolate one of t ...
i have an array of n length fullfilled by 16 bit (int16) pcm raw data,the data is in 44100 sample_rate and stereo,so i have in my array first 2 bytes ...
I have several questions on making a lowpass filter in python/scipy.signal. Would appreciate any answers. I'm trying to understand how scipy.signa ...
I want to create a script that will manually modulate and demodulate a signal. I am using DSB-SC modulation and I am just confused on how to build the ...
I am trying to read in all files in a directory, they are then low pass filtered. After that the results are saved one after the other but not in on ...
I need to filter some signals eliminating frequencies below 0.7 HZ and above 4 HZ (as suggested in the reference literature. I'm trying this on ...
My application requires to sample a sensor and send the samples out in real time, without saving the samples. I am required to run a low pass filter ...
I believe there's something wrong when I convert it back using ifft2(). I am trying to use the ideal low-pass filter by creating a matrix L that has a ...
In the documentation on lowpass I found this: y = lowpass(x,wpass) filters the input signal x using a lowpass filter with normalized passband freq ...
I have the following exercise from the university: The bit sequence [1 1 0 1 1 1 0 0] with data rate DR = 50 bps is given. This bit sequence modulat ...
I am trying to pass my audio through low pass filter, so as to filter out noise from it. However, the output of the wav is very noisy, and I am unable ...
