Hi everyone.

I have such problem: does not working adaptive volume on DSP.
JRiver 19. Windows 7. Play via USB to Asus XonarU7 [WASAPI], than from asus to NAIM DAC V1 SPDIF IN.
Now plays flac 16bit 44khz source, internal 64bit 44 kHz, volume - internal.

Other effects like a virtual subwoofer - works fine.

So, loudness function does not work too...

Can you help me to solve this problem please..

Ilja.

What makes you think it's not working?

Check the Audio Path while it's playing and it should show a gain / cut there.

By my ears, I hear it..

Can you tell my where is that audio path and how use it ?


Now tried DSD.. to open it, jriver says frequency must cut from 384 KHz, to 176.. and it plays and adaptive volume works! Night mode works!
So.. I think it must be because flac 16bit 44khz source, but internal is 64bit 44 kHz, 16 bit not=  64  bit
But DSD is 64bit source = 64 internal..

May be it ?

 Matt, thanks. It also worked, but I didn't notice because the algorithm of work such that on loud records is a little added by dB (+0.5..1 dB), and on silent, like a violin - there is more dB gain (+3. +7dB). Therefore on one record I heard, on another dont hear..
Thanks. Audio path helps to see it

So, another stupid question number two 
I push speaker icon, there I choose "loudness" and.. NO loudness I hear
Internal volume is selected. Also I try to select another.. Application volume, system volume.. Loudness do not work.
Also I do not see it on Audio path when Loudness is selected with tick.

The "Loudness" feature is not a setting to make things louder.
Adaptive Volume in the Night Mode or Small Speakers Mode is for that.

The Loudness feature applies Equal-loudness Contours to your music when the volume level is reduced, so that it is perceived to sound the same at lower volume levels.
Your system must be calibrated to a reference level of 83dB, and Media Center must be the only device in control of the volume for it to work correctly.
There is a lot of confusion over this, and the setting should be renamed in my opinion. (and possibly moved out of that menu)

The Loudness terminology has been in use for about 40 years. Many stereo preamps still have a loudness button - which is based on equal loudness contours. THX certified receivers call it Loudness Plus. Here is what it is called more recently:
Dynamic EQ - Behringer on their DSP products and Audyssey
Dolby Volume
Adaptive DSP - Yamaha

My mistake - I didn't realize that was what the loudness button on older devices did.

When I pressed the "loudness" button on my old amplifier I hear changes, but in JRiver I does not hear any changes. 
This function DO sound LOUDER. Because it push up dB level on some frequency which our ears hear more weakly.
Here on the picture you can see it https://en.wikipedia.org/wiki/Equal-loudness_contour

But it does not work on JRiver, and I want to find out why.. 
And steps how to turn it on  ?

The control in Media Center is a smart control as opposed to the "dumb" control in your amplifier.
The effect is increased the lower the volume is set.
 
It is supposed to be used with the speakers calibrated to 83dB and Media Center being used for volume control - though you don't have to do that.

[Ilja]

Brr..
Then its not necessary function and should forget about it.

+1 I dont though to do that.. I just though push the button and enjoy loudness.

Or have manual in help section how to calibrate speakers to 83db and media center for using volume control to use this Loudness..

[Ilja]

Can you tell me how calibrate speakers and jriver to use loudness ?

[Matt]

Can you tell me how calibrate speakers and jriver to use loudness ?

You use Tools > Advanced Tools > Audio Calibration > Volume calibration

You play that and set the volume to reach 83dB (I'm going by memory on that number, so please tell me if I'm wrong), then set the internal volume reference level to that number.

[Ilja]

Fuh.. Loudness works, thank to all.

You use Tools > Advanced Tools > Audio Calibration > Volume calibration

No need to do these steps.. just play any music and reduce a jriver internal volume, and than after selecting "loudness" it will works and you can see "loudness" in audio patch.

But to hear loudness well you need to reduce volume approximate in these range: -8..-20 dB. Just choose it on your own hearing.
83db it will be -17dB..

So, Loudness is very needed function, because "Adaptive volume" -> Night mode or For small speakers does not increase volume on music files which are recorded at the high volume levels, it increase them for about +0.2.. +1dB. You do not hear it. But if you need more loudness by dB up on these records - choose Loudness.

Badly certainly that in instructions not a word about it.
It should be corrected.
