You can playback 10 second sine sweeps (included) from a CD on a boombox at a film set, record the sweep with microphones, feed the recordings to the IR Pre Processor Application, and you have a sample of the room for use in ADR and foley.
Recording a sample this way happens at unoffending levels, so it is no problem if the crew is present. You can capture acoustics this way in a matter of seconds.
Portable, self powered playback equipment can be used. Audio Ease has sampled boomboxes to be able to make up for the ugly characteristics of their speakers.

Sampling acoustic spaces for Music
If you want to obtain the highest possible quality in your acoustic samples (Impulse Responses), you are limited to AC powered gear, but the basic method is the same: You playback sine sweeps (included) via a good studio monitor, record the sweep in the room with mics, feed the recordings to the IR Pre Processor Application, and you have a sample of a room. The longer the sweep you use, the higher the signal to noise ratio. The IR PreProcessor can handle 300 second sweeps so you can get clean Impulse Responses even in noisy environments. The complete procedure is described in this pdf:
