I use Rasp 3b+/Volumio 2 (latest firmware) and Minimserver on a Synology DS412+ NAS.
It’s working perfectly nevertheless some questions:
Usng the Volumio app on an Android device.
When I let the Raspi do the flac to wav conversion, I get the perfect data in my screen.
I always let Minimserver do the flac to wav conversion so the Raspi only have to transport the file. Then I loose my tags metadata and tracknumer showing $!transcode.wav
When I use the same file and use BubbleUpNP or BubbleDS this data is picked up normally.
So it is transferred some
No problem
No going in deep discussion. Flac is a kind of zipped wav file, it will be unpacked to make it a wav file. It will take processor time. A NAS is oing this easier then the raspi. Besides that for my ears a wav file sounding slightly more comfortable to my ears then a flac file.
Humm . A flac uses a free lossless audio codec. So no losses. Depending on compression, the file size varies, but uncompressed data are identical. in the best case, converting to an other format you will get the same data, in other case you’ll loose information…
Playing wav files will give a better sound than playing flac files. This is the broad consensus on the forum https://www.aktives-hoeren.de
The less the CPU is busy, the better the sound.
In the past, flac files were used because flac is a lossless data format and uses only half as much memory. But in times of cheap memory this is no longer important.
