http://www.notam02.no/arkiv/src/ Mammut will FFT your sound in one single gigantic analysis (no windows). These spectral data, where the development in time is incorporated in mysterious ways, may then be transformed by different algorithms prior to resynthesis. An interesting aspect of Mammut is its completely non-intuitive sound transformation approach. This is very minor update. If you already have mammut, theres probably not much point in upgrading. The "big" change in this release is the first entry in the changelog. I must also warn that mammut can be a bit hard to compile up, now that pygtk1 has been replaced with pygtk2 in all recent distributions I know about. 0.16 -> 0.17 -Initialize sound at startup, so that mammut appears in jack patch bays. -Removed the included sndlib binary. -Added a point in the INSTALL file about how to configure mammut to find the pygtk1 files. -Added a note in the INSTALL file about that sndlib for some reason does not work with delta cards when using the alsa driver. The oss driver (under alsa emulation), and the jack driver works just fine. --
