From 87ec849fe9acba075c843e67bcd01f256f481a18 Mon Sep 17 00:00:00 2001 From: Christophe Gisquet Date: Fri, 14 Feb 2014 15:03:06 +0000 Subject: [PATCH] dcadec: remove scaling in lfe_interpolation_fir The scaling factor is constant so it is faster to scale the FIR coefficients in the tables during compilation.
