| Mar 4, 2021 at 12:12 | comment | added | Marcus Müller | And a plot of the frequency response of your filter you've estimated would be nice, too. | |
| Mar 4, 2021 at 12:06 | comment | added | Marcus Müller | Hm, I think a good start would be the line of code that actually does the convolution of audio and the filter impulse response. | |
| Mar 4, 2021 at 11:15 | comment | added | Khubaib Ahmad | @MarcusMüller my max and min value is in [-1:1] | |
| Mar 4, 2021 at 11:14 | comment | added | Khubaib Ahmad | Can I share my files and Jupyter notebook? | |
| Mar 4, 2021 at 11:13 | comment | added | Marcus Müller | yeah, that sounds exactly like what happens when you drastically clip. Make sure none of the floating point values leaving your convolution are outside [-1,1]; other than that, you're asking us to debug your system, which you only tell us about, but don't show, so that'll be hard. | |
| Mar 4, 2021 at 11:10 | comment | added | Khubaib Ahmad | @MarcusMüller No sir, there seems no clipping because the recorded sound is from the laptop, and while visualizing the audio file in Audacity and In data (array) form, there is no clipping. It's more like robotic sound with static noise added. | |
| Mar 4, 2021 at 11:08 | comment | added | Khubaib Ahmad | @user12750353, Audio length is approximately 6 seconds at a sampling rate of 48000. I have made 21 ms of chunks for replicating streaming in real-time. My Impulse response is also of length 21ms i.e 1024 samples. | |
| Mar 4, 2021 at 11:07 | comment | added | Marcus Müller | are you sure you aren't clipping? | |
| Mar 4, 2021 at 9:18 | comment | added | Bob | How long is your audio? and how long is your inpulse response? | |
