From 6213cf73945db1dd488ec51d6c4214b496833d7b Mon Sep 17 00:00:00 2001 From: Rostislav Pehlivanov Date: Mon, 27 Aug 2018 23:12:36 +0100 Subject: [PATCH] atrac9dec: relax gradient value requirements Unlike the range, the gradient start value does not have to be lower than the end value. Does allow more files to be correctly decoded without errors.
