Playing progress example?

[kckrinke]

I'd like to see a clean example of playing an audio file and during playback printing out the progress of the playback (as in how many seconds, samples have been played, or position, or any useful indicator really).

I can't seem to figure out a simple solution based on the existing samples and reading the libsox documentation is painful enough that it's prohibitive for me to contribute this go-sox code myself.

I don't use sox that much myself, and I'm not sure if there's any simple way to get statistics out of sox while it's processing. But maybe someone who knows will see this issue :)
