![]() I'm not opposed to on-the-fly peak normalization (it's certainly better than baking it into the files!), but I'd like to understand the technical argument for it better. Even if your source is 24-bit, the last many bits are almost surely noise so you're not really removing "real" information with volume on those files either. Since I have the volume headroom, it doesn't change the sound quality at all.Īs 6233638 said, your DAC probably uses 24-bit, so turning a 16-bit down isn't actually removing information. If you were to do so, all of the dynamic range of the signal would be squashed and all the peaks would either be clipped or seriously compressed. Instead, I like the Replay Gain system that makes the volumes between songs sound about the same. If I peak normalized my songs, I might need -33dB for the same volume, so I'd get +3dB "for free." However, I already have 30dB more than I can really use so the 3dB isn't particularly helpful. This is a DAC hooked directly to a power amplifier. I'm trying to understand this request, so help me along.Īre you playing in a power starved system where you're looking for ways to squeeze extra volume out?Īs an example, on my home system, a comfortable listening level is about -30dB of internal volume. It's largely successful, but I would like to see a move towards R128, which should do a better job - maybe that is something for MC19 though.įor video, I believe Adaptive Volume set to Light does this, but there's no option for music playback. ReplayGain - which is what the Volume Levelling DSP utilizes - is based on analysis of your music, and normalizes around what it believes to be the "average" volume level for a track, so that tracks with a lot of dynamic range, and tracks with very little dynamic range, should all play at roughly the same volume. Matt is probably the person to ask about that. In reality, you need far less headroom though - the 3.5dB used in the DAC2-HGC is probably enough for "real" audio, and if you are using ReplayGain you probably don't have to worry about it.Ĭlipping protection may already handle it though - I'm not sure. You will also be susceptible to clipping due to intersample overs if you do this - which can approach 12dB in rare cases. This is the reason we have such compressed music in the first place, because that's how Radio and TV used to work. The more dynamic range a track has, the quieter it will be, so it biases towards highly compressed audio, which sounds louder when you use peak normalization. Now it is more like turning up the volume - nothing more.What you describe is Peak Normalization, which will not actually "normalize" the volume levels of your music. Historically, as digital audio quality improved, normalization no longer degrades the audio’s quality. If the volume was turned down, it reduced the bit depth. ![]() The poor reputation for normalization came in the early days of digital audio when all files were 16-bits. Performing digital processing to a file is going to change it in some way. It should be remembered that audio normalization is a destructive process. ![]() As soon as extra processing or play tracks are added, the audio may overload. Peak normalization to 0 dBFS is a bad idea for any components to be used in a multi-track recording. for matching volumes of different songs or program segments. It takes an average.Īudio should be normalized for two reasons: 1. There may be large peaks, but also softer sections. ![]() ![]() This considers the overall loudness of a file. Software offering such normalization normally provides the option of using dynamic range compression to prevent clipping when this happens. Loudness normalization can result in peaks that exceed the recording medium's limits. ![]()
