Creating Subdirectories for Multiple Disc Sets in File Conversion

Re: Creating Subdirectories for Multiple Disc Sets in File Conversion

I've also noted another odd result. Consider the following file name when ripped to FLAC

01-Symphony No. 4 in A major ('Italian'), Op. 90; 1st movement-Classical Masterpieces of the Millennium; Mendelssohn-Bartholdy-Berlin Radio S.flac

This file is in a single subdirectory called:
S:\FLAC\Berlin Radio Symphony Orchestra\Classical Masterpieces of the Millennium; Mendelssohn-Bartholdy

When converted to MP3 with batch converter, the resulting mp3 is named:
01-Symphony No. 4 in A major ('Italian'), Op. 90; 1st movement-Classical Masterpieces of the Millennium; Mendelssohn-Bartholdy-Berlin Radio Symphony Orche.mp3

but shows up in the following subdirectory:

D:\TempMP3Files\Berlin Radio Symphony Orchestra\Classical Masterpieces of the Millennium; Mendelssoh

That is, the subdirectory name is truncated. And it turns out that the files within the original FLAC subdirectory end up in about 7 or 8 different name subdirectories (all truncated versions of the original name of the album) depending on how long the ultimate name of the mp3 track file is.

I could see the length issue being a problem, but it strikes me as odd that the original naming of the FLAC files and subdirectories (from the ripper) didn't suffer from the same problem as the later mp3 conversion names/subdirectories.

Re: Creating Subdirectories for Multiple Disc Sets in File Conversion

Check your files have those ID tags written to them, specifially Disc and Compilation (only on compilation discs), without them batch converter cannot name the tracks.

Re: Creating Subdirectories for Multiple Disc Sets in File Conversion

The FLAC files do contain both disc tags and compilation tags (when the CD is a compilation).

The first code box is the file information from dbpoweramp for the FLAC file. This is from a two disc set. It does contain the disc field (note that it indicates disc is 1). The FLAC file has the Disc number in the file name. And when ripped to FLAC, the files are saved as:

Edith Piaf\Enregistrements publics vol. 2\Disc 1\filename.flac

Code:

Below is the information on the mp3 created with batch conversion. Note that it also indicates Disc 1. However, the file name doesn't include the Disc #, and the mp3 files are not created with the expected directory structure. Instead, the mp3 files are all in:

Edith Piaf\Enregistrements publics vol. 2\filename.mp3

The individual files continue to carry the Disc identifier in the tags, but the naming didn't work and the directory structure didn't work.

Code:

Artist Edith Piaf

When I have compilation discs, the batch ripper DOES place the mp3 album directories underneath the COMPILATION subdirectory as it should, but under album name, there is no separate Disc 1, Disc 2, etc. subdirectories as expected (and as does happen with the original FLAC ripping).

Re: Creating Subdirectories for Multiple Disc Sets in File Conversion

Although still interested in what I'm missing above, I have found a way to create the exact same directory structure with the mp3 files as I have with the FLACs. I use the following in dynamic naming. The original files are in
FLAC/Artist/Albumname/Disc#/tracktitle.flac

The mp3 files end up in
MP3/Artist/Albumname/Disc#/tracktitle.mp3

Code:

Folder:   D:\MP3\
Dynamic naming: [TRIMFIRSTFOLDER][origpath]\[origfilename][]

Re: Creating Subdirectories for Multiple Disc Sets in File Conversion

Install the [Audio Info] Codec from Codec Central, and run it (on default settings) on that FLAC file (one with Compilation set) please, post the results.

Re: Creating Subdirectories for Multiple Disc Sets in File Conversion

This file is part of a compilation disc that has four discs (this is from disc 1). You can see that the original FLAC file was placed in a separate disc subdirectory and included the Disc # in the file name. But when using the same dynamic naming for converting to mp3 (noted in first posting above) all four discs are in a single subdirectory for the album and disc # is not in mp3 file name. However, the mp3 files do contain the correct disc field.

Re: Creating Subdirectories for Multiple Disc Sets in File Conversion

Thanks Gary, will mark as a bug to look at.

**Spoon** · April 15, 2008, 12:37 PM

Re: Creating Subdirectories for Multiple Disc Sets in File Conversion

Gary,

Can you try R13 (the latest alpha version), I am trying your string:

[IFCOMP]Compilations\[album] [IFMULTI] \Disc [disc][]\[track]-[title]-[album][IFMULTI]-Disc[disc][]-[artist][][IF!COMP][artist]\[album][IFMULTI] \Disc [disc][]\[track]-[title]-[album][IFMULTI]-Disc[disc][]-[artist][]

On a flac file with Compilation '1' and it goes into a compilations folder (if using Music Converter >> dynamic naming).

**garym** · April 15, 2008, 01:07 PM

Re: Creating Subdirectories for Multiple Disc Sets in File Conversion

I'll do this in the next few days and report back.

**garym** · April 22, 2008, 07:56 PM

Re: Creating Subdirectories for Multiple Disc Sets in File Conversion

I've installed R13 and checked the behavior. I still get the same outcome. Note that the problem was not putting files under a compilation subdirectory, but putting files in separate disc folders under the album folder. That is, the FLAC files are originally ripped to separate disc folders under the album name when multidisc, but when converting the FLAC files with the same dynamic naming convention, the tag disc ID is correct, but all the song files are in a single album directory versus album/disc1, disc 2, etc. That is, in ripping song to FLAC with following dynamic naming:

Code:

[IFCOMP]Compilations\[album] [IFMULTI] \Disc [disc][]\[track]-[title]-[album][IFMULTI]-Disc[disc][]-[artist][][IF!COMP][artist]\[album][IFMULTI] \Disc [disc][]\[track]-[title]-[album][IFMULTI]-Disc[disc][]-[artist][]

Folders look like:

artist/album/disc1/track - title

(with disc 2, disc 3, etc. all falling under the album as separate subdirectories.

When using exact same dynamic naming to go from FLAC to mp3(lame) using the batch converter and selecting the directory with album (and lower level subdirectories with disc 1, disc 2) the songs all end up under a single album directory:

artist/album/track - title

All songs DO have correct Disc ID in tags, etc. See below for file info from FLAC and then from mp3.

Re: Creating Subdirectories for Multiple Disc Sets in File Conversion

Duh! The answer turns out to be quite simple. In my tagging options I've set disc to be simply disc number rather than disc number/total (i.e., 1/2). When ripping, the program knows that the CD is 1 of 2, 2 of 2, etc. But when converting, the FLAC tags only contain the disc number without the total discs and obviously there is no way for the program to know that there are multiple discs. Problem solved!
