- Cross-platform: available for OS X, Linux, Windows
- Native support for aiff, wav, mp3 and ogg (but what about AAC?)
- Annotations: Support for adding labelled time points and defining segments, point values and curves. The annotations can be overlayed on top of waveforms and spectrograms
Vamp Plugins is at the core of the Sonic Visualiser, and it seems like they want this to become a standard for non-realtime audio plugins. This seems like a good idea, and it will be interesting to see how this develops.
I have just briefly tested it, and it has not crashed yet (which is a good sign). It is not particularly fast on my PowerBook, but at least it is multi-threaded so it doesn’t freeze while doing the analysis.
For more advanced analysis, editing, and sdif export, I still prefer SPEAR.
