Thank you for the inputs I still have a few more queries (a) So is it that we do not need to go via OpenSL for a adding a custom effect. ? (b) In the link given below http://www.khronos.org/message_boards/viewtopic.php?f=33&t=3612
I understand that we can add custom effects by introducing a new interface in OpenSL . In the OpenSl framework implemented in Android is this feature not supported? (c)If supported , what would be the steps involved.
