iPhone: Echo cancellation may not work on iOS using SDK 4.x

Description

There were a couple of reports saying that echo cancellation works fine using SDK 3.x but doesn't work properly when using SDK 4.x. (on devices running iOS 3.x and 4.x).

This ticket investigates whether there is a problem with EC using SDK 4.x, and if possible, finds a way to solve it.

Note: using speaker mode is recommended to test the EC.

  • Resolution set to wontfix
  • Status changed from new to closed

iOS SDK version: 3.2 and 4.0.2

Devices: iPad (iOS 3.2.1), iPhone 3GS (iOS 4.0.2)

Result: Echo cancellation doesn't seem to work using iOS SDK 4 on both devices except if we don't use speaker phone on the iPhone 3GS (which is more likely due to the low sound volume).
