![]() The problem is the two surround channels - they are near-copies of the fronts so when downmixed the fronts are way too loud. I have tried increasing the center channel volume by as much as 12 dB, but it still sounds wrong. The center channel is used for Davids vocal in some of the tracks, but it is way too quiet when doing a normal 5.1 downmix. I believe this one is mastered correct because a downmix of all 5.1 channels sounds perfect and offers DR 10-13. I have done three albums, all SACD, and all needed to be downmixed differently: The disc needs to be authored/mastered correct otherwise it will sound horrible when downmixed. Then do an Amplitude Statistics Scan and check for Possible Clipped Samples.Ģ. You can verify this by converting your foobar2000 downmixed music to a single wave file and opening it in a sound editor like Adobe Audition. foobar2000 does not.Ĭlipping is most likely the reason for your low DR with foobar2000. The software needs to do a 2-pass operation in order to find the proper output volume and prevent clipping. There are two issues with stereo downmixing that makes it a nightmare:ġ. What changes the result? What is causing the increase or decrease of DR with the result file? I just want a stereo file as dynamic as the original and i want a way to make it somehow with a standard result. I am now not sure if foobar does the job or what. Tried Opeth - Ghost Reveries AC3, downmixed. Downmixed it to stereo with foobar, now it clocks at DR13. DR shows 12 (track, Coming back to Life) with original 5.1 flac. ![]() Then i tried Pink Floyd - The Division Bell 5.1 flac with foobar. Then ripped it 5.1 and used foobar to convert to stereo. Ripped it (as 5.1 to 2.0) with DVD-A extractor and dynamics are intact with the result (DR14). I used Refused - The Shape of Punk to Come DVD-A to experiment. Also foobar does the job with flac files but there's a catch to it. It kinda is easy with a DVD-A disc, DVD Audio Extractor does the job. I am not sure how downmixing covered on the forum exactly cuz i couldn't find much. ![]()
