From 943dc942659c61b273ba219d5891af6e7510c8b3 Mon Sep 17 00:00:00 2001 From: Justin Ruggles Date: Thu, 10 Feb 2011 22:12:16 +0000 Subject: [PATCH] ac3enc: Remove unneeded clipping of shift amount. s->windowed_samples will always have a range of [-32767,32767] due to the window function, so the return value from log2_tab() will always be in the range [0,14].
