To confuse me even more, apparently ‘0dB’ in digital isn’t really 0dB, but has some ‘headroom’ calculated in to allow for that. And of course, when you run out of bits, you’re straight into hard clipping.

Now there are multiple volume controls along the way. This is all pretty confusing because when I started in audio back in the Mesozoic, you just turned the knob until you got the volume you wanted. Fidelia has a ‘Prevent clipping’ checkbox in its prefs but provides no info on how it operates. VLC has a tick mark on its volume slider that seems to correspond to unity gain, but it’s the only one. Since Tidal has this recording, I found the same passage and adjusted the volume the same way. I just back down the player volume until it stops turning red. So far, the champ is ‘Trilogy’, a Chick Corea live recording. So far, I have done this by finding the recordings in my collection with the loudest peaks. I want to pass the signal to the DAC at the highest level possible without delivering a clipped signal downstream and then control volume after the DAC, in the analog domain on my amp.

So that's where I get into calibration, which is what my main question really is. Even I know that a clipped signal is not ‘bit-perfect’. I want to control the volume in the analog domain. Also, it seems to me that if any source I am listening to is outputting a clipped signal, turning the volume down after-the-fact is not going to ‘un-clip’ it. As I just mentioned, changing the system volume going into the DAC can only be done in SoundSource. This results in clipping on peaks, verified by the indicators in SoundSource. Namely, all of the players mentioned above apply gain to the signal at their maximum volume settings. SoundSource does have a volume setting for it, but (AFAIK) it won't help with the second (and bigger) problem. There are a couple of problems with this.įirst, when the the DAC is selected as the output device, the system volume setting is grayed out. The standard advice I see (including from rogue amoeba) it Is to max out the volume control on the source, and control the volume using the system volume, to get ‘bit-perfect’ playback. That's where I discovered I had a problem: All of the Applications mentioned above have their own volume controls. They are useless for determining actual sound levels, but they have one very handy feature: they change color to red when the signal is clipping. I often use one designed for headphones which gives a more natural stereo image.Īmong SoundSource’s features is little level meters. It also allows me to use plug-ins with any sound source. Not long ago, I installed the latest release of Rogue Amoeba SoundSource, a little utility that allows me to control the routing of sound the computer. Whatever I am listening to goes out to an external DAC, and from there to an analog amplifier.

Main ones are Swinsian, VLC, Fidelia, Vox, and occasionally even iTunes. I stream Tidal and Idagio lossless, and use a variety of players according to my mood to play back local files.

I use my 2018 Mac Mini as my primary source of audio playback.
