Freesound Forums

hallo,
I am new to the freesoundproject and I am very curious about the work you are doing here. I very much like the idea of showing the waveform (or a piece of it) of every sound. I am currently working on a project where I am trying to find visual representations for voice sounds (not a music visualizer). I am interested whether it is possible to "read" a waveform (or other kinds of sound visualisations) in order to get information about the content or structure of human conversations (e.g. number of speakers, overlappings, emotional state..). If anyone knows if thats possible please tell me.
Another question: the waveforms you are showing to each sound file have different colors, why is that? they range from dark blue to yellow. Maybe it is obvious, but I am totally new to this field, thanks for any answer, Juli

perhaps you should have a look at our latest blog item:

@Bram, I have seen the latest blog item and it looks quite interesting, however I can't find an explanation of the graphical representation of the wave form. How do the colors effect the waveform? thanks for your help, Juli

Would a Color Spectrum analyzer do the same thing? there is one way to visualize them probably things like Bits Herts, format - ANSI and such. . . .It might work on frequency levels and blue is probably a higher KHZ frequency with yellow being a distorted and lower frequency with less Bits, Hertz and such. I don't know. . .
