Thanks very much for all the help so far.
So far, I've been able to manually isolate crackle waveforms by:
1) Loading the lung sound .wav into Audacity
2) Display the sound signal in Spectogram (Shift-M\spectogram). Here I get to see the explosive crackles along the signal.
3) VISUALLY...
Is there a bandpass filter in Audacity?
I only see High-pass, low-pass and Notch (Bandstop) in the Effect menu.
I loaded a 10-second .wav file of lung sound with fine crackles into Audacity, zoomed into the first second and applied a high pass filter at 100Hz. The shape of the expected crackle...
Hi BradtheRad
Thank you very much for replying.
I do have Audacity, MATLAB 2011b (with DSP and Wavelet Toolboxes) and LabVIEW 2011 to use.
Had thought MATLAB's Wavelet toolbox was the most appropriate tool for the job since articles I've read usually use it.
I do know that fine crackles are...
Hi,
I'm in a situation....
I need to analyse lung sounds samples to detect crackles present in them and further classify these crackles by their characteristics for a project.
Having read some articles that have done such analysis, I figured the wavelet toolbox in MATLAB is the best tool for...
