FFT Analysis of audio signal - RiotDevices clean booster

Hey guys, a small video about FFT Signal Analysis using open-source software.

Comments are greatly appreciated.

Interesting video, thanks for taking the time to do it. After watching it I installed Jaaa and it looks like a pretty useful tool, using the noise generator you could use it to plot the frequency response of circuits, might be a good idea for a future video.

Indeed Slacker,

The only cons for this pice of software is that it doesn't plot other diagrams ... that would have been nice

Cool, are you sure you are not overdriving the input of the soundcard?

[gtudoran]

@~arph: yes 100% sure, but for this type of test (if you think that the signal level is too high) you can use a small divider (of a known value 1:10 or 1:100). The soundcard has a clipping led indicator

Ok, you did a good job

Thank you ~arph, hope it will be of some help for someone i know it helped me in some cases.
