The thing is, sound doesn't travel all that fast when you consider the wavelengths of vocal-range soundwaves. Those spikes are not going to arrive at the same time on the different phones.
As ever with DSP, phase problems will be the ruin of you.

Or do you mean that different frequencies will travel at different speeds, enough to make (e.g.) high and low frequencies arrive at different times? Whoa, apparently it does (http://en.wikipedia.org/wiki/Speed_of_sound#Effect_of_frequency_and_gas_composition http://en.wikipedia.org/wiki/Speed_of_sound#Effect_of_freque...) but seems to be a small effect.
- JonnieCache 15y agoWhen setting up a big sound system, you have to delay the bassbins by up to 10ms, depending on the size of the cabinets. Also, how do you calculate your offset? Consider that it is constantly changing.
