Each region in a file is a spoken word in a sentence. I need a way to get the average loudness (RMS?) of each region (word) returned as a percentage. Can this be done with scripting?

Also, is it possible to extract the volume info of the waveform into numbers taken at specific intervals for redrawing a rudimentary representation of the waveform in another program (ie Flash)? Or, should I use a third party program for something like this?

thanks... I hope this is enough info to start solving this problem...

You can do this using statistics over an SfAudioSelection. see the
StatisticsTest.cs script in the SDK

Thank you.. That seems like the place to start.

What is ReadAudio() used for then?

Sorry for asking silly questions...

Is there an example somewhere of using SfAudioSelection to walk through an audio file in specific time increments or by markers?
