I'm exporting music to a external device which does not support volume leveling. For the device, "apply DSP settings" is marked. I would expect, that the volume level is then hard coded into each frame and the Volume Level fields set to zero. But playing music with my device (iPhone / iPad), level still jumps around, which is hardly tolerable. If I misunderstand the function "apply DSP settings"a, please let me know.
Since JRemote doesn't honor the volume level information (Any reason for that?), I exported all files to a different folder using "apply DSP settings". I used a separate database to manage those files, but even running the "analyze audio" makes no change to the level (It should be close to 0 now).
To me, the DSP settings are not applied during the conversion process. I tested it by using three files 440Hz, 0db / -6db and -10db. When VL is working, all three files play the same volume (as on my PC), if not, there is a noticeable difference in volume. (the attached files need to be analyzed first)

You're playing locally on the (iPhone / iPad) with JRemote and you have transcoding turned on in JRemote?

Hi Bob,
yes, I'm playing locally with JRemote and transcoding is turned on. Like I mentioned before, I checked several methods so far, but there was no way, to hardcode VL into the export file or to use it with JRemote.
Once more for my understanding: if I play eg. the attached files after vl, they should play almost with equal volume. (It is true for local playback at my PC, not for JRemote or any external device mot honoring the vl-tags).

We talked about this a bit just now.
There isn't any DSP VL being applied to the MCWS transcoding and the tags are not preserved through that process so that the file length can be calculated in advance.
There are a couple of approaches to dealing with this.
It would be interesting if you could do a test playing non-transcoded material and see if the underlying player in JRemote (libbass) pays attention to the VL tags.
Knowing this would help in making a decision on how to handle the issue.

I've tested transcoded and non-transcoded files before and could find no difference. Also, I played the test files in JRemote (transcoded and non-transcoded) and find, that the player did not pay any attention to the VL tags. To me, the easiest would be, to teach the JRemote player to apply the VL values during playback.
