This is another whopper like PRAAT. This one was developed at the Royal Institute of Technology (KTH) in Stockholm.
So SIT then.
It's cool and cheap and does the job. This is like the IKEA of speech tools. Maybe too high-level though. Let's see:
The Snack Sound Toolkit is designed to be used with a scripting language such as Tcl/Tk or Python. Using Snack you can create powerful multi-platform audio applications with just a few lines of code. Snack has commands for basic sound handling, such as playback, recording, file and socket I/O. Snack also provides primitives for sound visualization, e.g. waveforms and spectrograms. It was developed mainly to handle digital recordings of speech, but is just as useful for general audio. Snack has also successfully been applied to other one-dimensional signals.Yep. Bit beyond me. But this is the new goal: technology-literate teachers who also work outside of universities.
The combination of Snack and a scripting language makes it possible to create sound tools and applications with a minimum of effort. This is due to the rapid development nature of scripting languages. As a bonus you get an application that is cross-platform from start. It is also easy to integrate Snack based applications with existing sound analysis software.
