WiiM Replay gain and Synology NAS

[Manusz]

Please help me understand a Replay gain issue I experience.

First of all the configuration:
Synology Diskstation DS220+ running DSM 7.2.2-72806 update 2
Synology Media Server, version 2.2.1-3406
Wiim Pro, firmware 4.8.639134
Wiim Home App 3.0.5.24121118 on iPad

The WiiM Pro is connected via optical out to my NAD stereo amplifier
Both NAS and WiiM Pro are connected to my router via cables

The Diskstation stores a lot of CDs ripped using dBpoweramp, the files were saved with Replay gain tags.
I use the WiiM Home App to select music files to be played from the Synology Media Server.

When I listen to Internet radio stations the WiiM volume is usually set to 40 or 50 which, combined with the -20 dB volume setting of my amplifier, produces a sound level I like.
When playing the ripped FLAC files I have to increase the WiiM output to 60 or 70 to obtain a similar sound level.
When I play purchased FLAC files a WiiM volume of 40 or 50 is sufficient again.

So it seems that the Replay gain tag in my ripped files is not supported in this setup.

In release notes of recent WiiM firmware updates I see that WiiM have been working on support of Replay gain of various on-line services.

This makes me wonder if support of Replay gain in the Synology environment is something that could be solved by WiiM?

Hi Manusz,

A new firmware and app update will be released next week, introducing replay gain support for NAS and USB Media Library. Stay tuned!

Slighty off topic: does replay gain alter the quality of the sound?

Only the same way that volume would.

Thank you, you just made my day!

If you think your local tracks with Replaygain are quieter than internet radio now they will probably be even quieter when replaygain is enabled by WiiM.

Does Replaygain use embedded loudness data or will the file be analysed upon playback?

I don't know if I maybe need to analyse my library. Running Plex on a Synology unit here, but most of it was ripped with iTunes.

It reads tags, it doesn't analyse the files.

You have to scan the files first, I use foobar. It then applies metadata, like artist/track number etc.
