Has anyone tried Google Sound Amplifier?

Hi,

Is anyone familiar with Google Sound Amplifier? I’ve tried it only once (I don’t have any Android phone) and it seems that the lag is very very little, unlike many iPhone apps I’ve tried that stream with very bad latency.

For the records, Google Sound Amplifier works like iPhone Live Listen (which btw is not available with Phonaks) and lets you use the phone as a microphone with noise reduction functions, good for noisy environments.

Please let me know your experience!
Thanks!
