Dnuos is a console program that creates lists of music collections, based on directory structure.
For example, a list might look like this:
Album/Artist | Size | Type | Quality =========================================================== Ambient | | | Alva Noto | | | 2001 - Transform | 70.9M | MP3 | -V2 2004 - Transrapid | 30.2M | MP3 | -aps 2005 - Transspray | 31.7M | MP3 | -aps 2005 - Transvision | 32.3M | MP3 | -aps Alva Noto and Ryuichi Sakamoto | | | 2002 - Vrioon | 72.6M | MP3 | -aps 2005 - Insen | 99.1M | MP3 | 320 C 2006 - Revep | 27.9M | MP3 | -V2n
The list format is completely customizable and can be plain text or HTML.
Dnuos supports MP3, AAC, Musepack, Ogg Vorbis, and FLAC audio files. Quality profile detection is also supported, including LAME quality preset information.
Audio file information is saved to disk after a list is made for the first time, making subsequent lists much faster to generate. Only audio files and directories that have been changed since the last list was made are analyzed.
Dnuos is based on code from Oidua. Oidua makes similar lists, but is much older, has fewer features, and is no longer maintained.
Run dnuos --help for a full rundown of the available options.
Extract the archive and run make to install it:
tar zxvf dnuos-*.tar.gz cd dnuos-* sudo make install
This will install a console script named dnuos into /usr/local/bin. (On Mac OS X 10.4 and earlier, it may get installed into /Library/Frameworks/Python.framework/Versions/Current/bin.)
Once installed, open up your favorite terminal emulator and run dnuos. On Mac OS X, Terminal might be a good choice (located in /Applications/Utilities/).
There's no installation. Just extract the zip file where you want to install it. You can run the program in the command prompt with dnuos.exe.
After extracting Dnuos, press the Windows key and R to bring up the Run dialog. Type cmd and press enter to start the command prompt. Then type the drive letter the .exe is on, and cd to the directory with the .exe file. From here, simply run dnuos.exe.
If terminals and command prompts aren't to your liking, you can try one of the following graphical front-ends instead:
- Version 1.0.6 (May 31, 2008)
Made the Makefile more consistent across platforms. This now the recommended way to install Dnuos.
Fixed album and artist information not being populated for FLAC files. (Cached directories with FLAC files will be rescanned.)
Fixed potential Unicode error crashes with file names that aren't properly encoded with the file system's character encoding.
- Version 1.0.5 (May 5, 2008)
- Fixed potential Unicode error crashes due to UTF-8 cache format transition.
- Version 1.0.4 (May 4, 2008)
Greatly improved support for file and directory names with Unicode characters on Windows. Dnuos should now be able to scan folders and open audio files with Unicode characters in their paths, and Unicode characters can now be used in command line arguments.
Improved cache format support between Python versions.
- Version 1.0.3 (Apr. 27, 2008)
Fixed a crash with malformed locale environment variables (e.g. LANG, LC_ALL, etc.)
Fixed incorrect output when scanning root drive folders on Windows (e.g. C:\).
- Version 1.0.2 (Mar. 29, 2008)
- Fixed -V/--version not working in regular output.
- Version 1.0.1 (Mar. 24, 2008)
Improved printing of ID3 tags with null bytes.
Fixed Python 2.3 compatibility.
Fixed possible cache-related crash on certain Mac OS X environments.
- Version 1.0 (Mar. 20, 2008)
Added --delete-cache for deleting the cache directory and --cull-cache for removing non-existent directories from the cache.
Updated French translation.
- Version 1.0b7 (Mar. 10, 2008)
Updated French translation with corrections.
Fixed crash on displaying sizes in terabytes or higher.
Fixed Unicode-related crashes. UTF-8 is now used unconditionally.
- Version 1.0b6 (Feb. 24, 2008)
- Fixed cache creation not working on Windows.
- Version 1.0b5 (Feb. 23, 2008)
Added -L/--list-files for listing individual files in directories. Information about individual files isn't cached, however.
Added -u/--unknown-types for listing directories with unsupported audio types.
Fixed creation of the cache directory failing.
- Version 1.0b4 (Feb. 22, 2008)
Added support for locale-specific number formatting.
Fixed Audiolist tag crashing on VBR MP3s.
Fixed crashing on inaccessible directories (now ignored).
Added support for gettext-based translation.
Added a French translation.
Fixed theoretically possible zero division error with -t/--time.
Fixed issues with the cache not caching correctly (and non-existent directories now get culled from the cache).
Improved the cache implementation so it's loaded incrementally instead of all at once before a list is printed.
Fixed -e exclude directory switch not working with relative paths.
Fixed crash with -w/--wildcards.
Fixed -m/--merge not working properly on Windows.
Improved unit test coverage and fixed Windows portability issues.
- Version 1.0b3 (Dec. 25, 2007)
Added support for saving the cache even when Dnuos is interrupted.
Renamed -p/--parallel back to -m/--merge, as it does just that.
Fixed -i/--ignore-case not working.
Marginal speed improvements in audiotype and id3 code.
Removed a substantial amount of unused code in the id3 package.
Fixed possible crash with new vendor output field in certain cases.
Fixed parsing errors with Ogg Vorbis files and added vendor support.
Reduced win32 package size.
- Version 1.0b2 (Dec. 7, 2007)
Updated and consolidated documentation.
Fixed setup.py sdist not including all files.
Fixed handling of MP3s with VBRI headers (e.g. made by Fraunhofer).
Fixed serious issues with ID3 code that made it probably never work.
Fixed an import of set() (should improve Python 2.3 compatibility).
Switched from pickle to cPickle (when available) and switched to the most efficient pickle format (should speed things up quite a bit).
Made cache directory finding more robust.
Added support for saving the cache mid-list, so if you cancel making a list, it'll cache what it already listed.
Added a friendly error message for output strings with invalid fields.
Added a Makefile that runs setup.py.
- Version 1.0b1 (Dec. 2, 2007)
Significant code overhaul.
Added audio metadata caching.
Added the ability to filter out directories with mixed files.
Added proper distutils/setuptools support.
Added AAC bitrate calculation support.
Added V output flag that prints the encoder info (only MP3s for now).
Cleaned up help message (uses optparse now).
Removed -m/--merge switch.
Dropped support for Python 2.2.
- Version 0.94 (Jan. 16, 2006)
- Fixed endianness issues on big-endian machines.
- Version 0.93 (Jan. 13, 2006)
Fixed regression with MP3 header detection.
Added experimental VBRI header support.
- Version 0.92 (Jan. 13, 2006)
The -l (LAME MP3s only) and -v (VBR MP3s only) switches now work in regular output.
Added -b switch. Allows filtering of MP3s with bit rates lower than specified by -b.
- Version 0.91 (Jan. 12, 2006)
- Made finding of MP3 headers more robust. MP3s encoded at -V 9 with LAME 3.97b1 no longer confuse Dnuos.
- Version 0.9 (Jan. 11, 2006)
- Finally forked Oidua! This is now DNUOS!

Running the test suite requires the test data (in the same directory as setup.py). Once you have it, you can run the tests with the following command:
python setup.py test
