If you want to try the ffdshow method, here's some screenshots and a link to the RockSteady plugin. It works fine for XP but I couldn't tell you if it gets uglier to use on newer Windows. You can enable RAW audio in the list of codecs and it'll process the decoded audio. It also requires a DirectShow player such as MPC-HC.įFDShow doesn't need to be decoding the audio. You can't send DTS or AC3 directly for decoding by the receiver/TV as it can't be compressed. ![]() I do it with ffdshow and a Winamp plugin, but the Winamp plugin only supports stereo (miltucjannel audio will pass through uncompressed), so you have to downmix it with ffdshow first if it's multichannel (Potplayer no doubt has downmixing options too), and it has to be decoded by the PC. I'm pretty sure Potplayer also has that sort of normalisation built in, and the normalisation included with SMPlayer looks suspiciously like it works that way (I haven't tried it). That's how the normalisation built into MPC-HC and ffdshow works. Some players have a setting called "normalisation" that drops the volume when it gets loud and then slowly increases it again until there's another loud part, but I hate the sort of normalisation. That'll compress the audio and there'll be less difference between the soft and loud parts. The easiest option might be to check your TVs audio settings to see if it has a night mode. I wrote most of the stuff below before remembering about Potplayer, but it'll help explain using RockSteady if you'd like to try it anyway. I don't use Potplayer myself, but that's what I remember. if you use Potplayer I'm pretty sure it borrowed audio filters from ffdshow so it has the ability to load Winamp plugins itself, and maybe other types of plugins, so you wouldn't need to install ffdshow, and I think it has some reasonable methods for compressing the audio built-in, although I prefer my RockSteady configuration. Since I haven't adjusted all my recordings to the EBU target, I have followed the replaygain LUFS target instead so I'm reducing levels by at least 4dB.Edit: This will make sense after reading the rest of the post. When I run r128/bs1770 gain analysis tools on MuseScore's generated MP3s, it generally tells me they are 9+ dB too loud. In 2015 Youtube made LUFS loudness normalization mandatory and Spotify made it the default. In 2013 Apple began requiring their Sound Check, which does LUFS normalization, for all music on their streaming service. In 2011 the ITU modified their (2006-issue) standard to basically match the EBU, and it started to be more widely used in broadcasting. The EBU standard (which is slightly superior to ReplayGain) was released in 2010. Though ReplayGain was created in 2001 and was seen as best practice by audio enthusiasts, rational ways of normalizing levels didn't hit the mainstream until the 2010s. In the broadcast world, it resulted in overcompressed, overly loud channels, as well as ANNOYING COMMERCIALS WHICH ARE MUCH LOUDER THAN THE PROGRAM MATERIAL TO GRAB YOUR ATTENTION. In the world of CDs it led to the loudness war (see wikipedia). Part of the idea is that without a standard for loudness, people try to get more attention by making their material louder than everyone else's using dynamic range compression. ![]() It has extremely poor correlation with human-perceived loudness. ![]() Peak signal normalization is NOT a reasonable way to standardize levels. But there is no real disagreement that setting a LUFS target is the proper way to normalize and that the target should be relatively low. Some people recommend ReplayGain's target of -18, or something in between. The EBU standard of -23 seems to some to be overly affected by broadcast needs and too much of an adjustment for other audio. There is some difference of opinion about what the target level should be. It defines an algorithmic measure (LUFS) which very closely matches human-perceived loudness and gives a standard loudness level for recorded works. If you've ever heard of ReplayGain, the standard does much the same thing. Though the EBU and the BS series at ITU are broadcast-related, the standard isn't just intended for broadcasts.
