From 267287407adfbf62da2444ca2683cbc4814d901e Mon Sep 17 00:00:00 2001 From: Gustaf Ullberg Date: Mon, 4 Jun 2018 19:04:40 +0200 Subject: [PATCH] AEC3: Set default down sampling factor to 4 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This change sets the default down sampling factor of the delay estimator 4. Down sampling factor 8 is still problematic for some signals.
