It needs to clip on voice peaks, so, I'd think in the milliseconds sort of time frame, implying a 1 kHz sort of bandwidth. I haven't figured it out from the schematic yet on my IC7000, but it's an all analog circuit with direct feedback to the Tx IF drive amplifier. Since FlexWire uses I2C (as I recall), which is no ball of fire, speed wise (although 100 kbps is easily doable, with 10kilosamples/sec possible without working too hard) that might set a limit on the performance of the ALC logic, if you're doing a simple "voltage in to set gain" strategy.
