Access audio from script/extension

My editing workflow involves adding a lot of cuts during breaks in speech. This is a task that often takes several hours, but could be easily automated if I was able to access the raw audio data or peak files from a script or extension.

Is there a way to access the audio track data in some way? I'm happy to use any technique/language that allows me to access this information.

Thanks!

There is no direct access to audio (or video) available, from within an extension.

However, you can render any range of a timeline, to any output preset, including "audio only" presets; that should get you the audio you need to analyze.

Thanks for the info! Is there any documentation for the .pek files generated for audio waveforms? If I was able to parse them I could probably work around not having direct access to the audio. From a quick look it appears to be mono signed 16-bit PCM with some sort of header and padding between channels. The sample rate seems to be around 345 Hz which seems a bit arbitrary - although it's awfully close to 44100/128.

No, nor will there ever be.

Guidance: Do NOT rely on .pek files, ever.
