![]() ![]() Then of course being able to chose only stereo or only multichannes, DFF etc -> all the input / output options of sacd_extract.exe. It actually works and the tags stay synchronized for several hundred ISOs at a time. Sounds scary, but I’ve done it for a library >1’000 ISOs (with a lot of help from the guys in the jRiver forum I am very grateful for). Classical tagging is a brainteaser that has driven many people close to despair.īasically what would be needed is an ISO to DSF conversion utility that has the following modes of operation:Ĭonvert all the files within an ISO and dump the DSFs into a artist / album directory structure based on the metadata within the iso.Ĭonvert all the files within an ISO and dump the DSFs into an identical directory / album structure the iso was in.įrom there on the user would be free to extract the artist / album metadata from the path name and put them into the DSF file’s tags if he / she wishes.įrom there on there one can use the tags copy / paste functionality within jRiver to copy all user defined tags of the ISOs to the DSFs. Roon is by far the best quality of metadata I have seen to date, but again, it is not perfect and certain elements of the metadata I will have to enhance with my own manually input data. I absolutely want to keep this rigid database in the background when I switch to Roon. Currently I have a very consistent database, that goes across FLAC, mp3s, SACD ISO, the lot. Becasue ID3 tag fields are not made for classical you have to misuse some of the fields to store information). I have over the years developed a naming convention for the different fields (what goes where. So everyone enhances the existing metadata with information of their own that suits their preferences. ![]() It gets worse with opera.Ĭurrently there is NO perfect meta-database for classical and I doubt there will ever be one. So if you want to search for ( ) as opposed to ( ) again with Oistrakh as soloist but a different conductor, then the fun begins. While pop basically only uses artist and album, classical uses artist, composer, album, conductor, soloist and others, depending on the database or sacd or the user’s preferences. It’s even worse with the eastern Europeans or Russians. The metadata within the ISOs is all over the place and really unuseable:ĭepending on the origin of the SACD. I have been dealing with the tagging issue for classical music for many years. The users will be the ones that need to convert the ISOs to a DSF structure that roon can handle, which is no easy task given the ultra primitive conversion tools available today. So it’s a bloody conundrum and I truly don’t know which path would be easier for roon and the users. But that is a two edged sword as something like sidecar tagging is needed to store the metadata outside the ISO. The other option for roon of course would be reading the ISOs directly, then everything would be one place and the metadata of the SACD embedded in the ISO (which is quite extensive and contains unique identifiers to the SACD) would be available as well for identification. So that can be handled - as long as the DSF files of one SACD sit in one directory and the tracks are correctly numbered. ![]() And if the DSFs are in the right sequence it could also tell from the metadata where in the sequence the multichannel tracks start. Roon could definitely tell from the DSF itself whether it is stereo or multichannel. All conversion tools I know of are based on sacd_extract.exe and convert stereo and multichannel in two separate batches and the DSFs end up in two separate directories, which is a bummer. Once I start converting them to DSF, the problems start. ![]() That’s exactly where the issue is buried. The main issue with the conversion is that all the ISO to DSF tools that I am aware of convert either the stereo or the multichannel tracks during a batch, but not both. I am asking, because I am looking at different ways to convert my >1’000 SACD ISOs to DSF and depending on how this needs to be done it is a larger or smaller effort. In order for roon to do something sensible with SACD content in DSF format, I would assume that the DSFs for both stereo and multichannel tracks would need to sit in the same directory in order for roon to identify them as belonging to the same SACD. With an SACD ISO the stereo and multichannel tracks sit in the same container, so I would assume that the metadata set roon has for a specific SACD content contains both the stereo and multichannel tracks.Īt this time let’s not discuss the merits of being able to play SACD ISOs in roon, but let’s assume that the ISO has been converted to DSF files. In my view one issue with Multichannel is how metadata is handled for SACD material. The NADAC is certainly a DAC I am following closely. I heard the multichannel demo in Munich and I must say, it was extremely impressive. ![]()
