Table of values for the specific channel of the sound

I want to write a function that takes sound data and number as input and gives back table of values for the specific channel of that sound.
I have 2-channel sound:
sound = InputForm[Play[{t Sin[2000 t], (1 - t) Sin[2000 t]}, {t, 0, 1}]]
InputForm gives me SampledSoundFunction for all channels, but I need only for the chosen one. Is it possible to do this?
