Hi all, Is anyone aware of any application as in the subject? With live I also mean audio output from another (jack) source. AFAIK there are only baudline [1] and freqtweak [2]. Baudline seem very well done and it supports jack, but I personally find the vertical scroll a bit awkward (personal taste) and it doesn't seem possible to zoom to a specific frequency range or have two separate channel views. Freqtweak also has a vertical scroll, and although it looks a pretty cool software I can't seem to successfully select the jack source. One sonogram software which really rocks is Sonic Visualiser [3] but (as it's more intended for analysis and in fact does much more than sonogram) it doesn't have live input. Really I'd be happy with a simple horizontal scrolling sonogram ideally with frequency zoom just to 'see' audio I'm working with (I know there are very nice spectrogram applications, but for certain stuff I prefer sonogram), e.g. in the style of the built-in sonogram of MAX MSP. Suggestions, pointers et cetera appreciated. Lorenzo [1] http://www.baudline.com/ [2] http://freqtweak.sourceforge.net/ [3] http://www.sonicvisualiser.org/
