Objective: Identify when sound starts in an audio file, then add a few seconds of silence before that point and resave the file.

The "crop" message works great to chop off the original silence but there seem to be no ways to add silence without rerecording into another buffer. This can't be done real time in this project as some files would be too long.

any ideas on how to add silence to the buffer~ ... without strange externals?

I tried using [poke~] and [count~], this merely overwrites the start of the buffer - one would have to be able to dynamically shift the end point of the buffer too, thus resizing it and wiping its contents. I can't see another way of doing this without using 2 buffers........

Can I ask the purpose of this? If it's not realtime, can you not add silence in an audio editor?

Well I think I have another way to get around this. It was to find ways to prep files for Ableton that might have some silence. You can add "silence" to the ableton file by faking the start time so I think this will work for now.. however I could see why this would be useful in the future or for others if anyone else has ideas. You would want to do it in a programmatic way, like be able to batch process it. Looking in an audio editor for when the sound begins and the adding a specific amount of time before that would be cumbersome for many files.
