how to compare two huge music directories playback length and file count of corr

rupeshforu3:
Hi I am Rupesh from India and I have a huge directory of size 150 gb of which 93 gb are mp3 files which are speeches recorded by someone at 64 kbps and remaining are music files with bitrate between 96 kbps to 216 kbps.

I want to compress all these files and store these in external memory card. Upon performing a number of experiments I came to conclusion that opus codec is best for speeches and mp4 files generated using aac(Nero acc encoder) is best for music with crystal clear quality at even lower bitrates.

I have converted 93 gb speech files to opus files and occupied 30 gb and converted remaining music files to mp4 files which occupied 20 gb. I have choosed lamexp for conversion which is a best open source software which combines binaries of other encoders including lame, opusenc, NeroAacEnc etc.,. For opus encoding I have used 11 kbps,16 kbps and 24 kbps. For aac encoding I have used 48 kbps and 56 kbps. For all encoding I have used 48000 Hz sample rate.

Even though I have used lower bitrates for conversion the resulted output files are of acceptable quality. The output file names generated and directory structure are identical to source.

During conversion very few of the original files are ignored and so no output files generated for those. Some very few of files are not transcoded properly I mean suppose source file is of 50 minutes length it was transcoded to a file containing 5 minutes or 10 minutes in length but the source and destination file names are identical. I have noticed those differences by examining some source and destination directories.

Sometimes I think that a huge amount of files are not transcoded properly as illustrated above. I want to compare source and destination directories and obtain a list of files with paths which are not transcoded properly.

Suppose I have a directory of size 23 gb and 2400 files and I have transcoded to a destination directory of size 5 gb and 2200 files.
can anyone of you suggest how to the list of the missing 200 file's.

Suppose I have a directory of playback length 600 hours distributed into various files say 1000 files and I have transcoded these files and the resulting file count is 1000 of playback length say 500 hours.  Can anyone of you suggest how to obtain the list of files with paths which are different in playback length.

Atleast can you suggest how to obtain the playback length of the total directory which contains 150 files.

In playtime app I am unable to see any entries when I add a folder containing mp3 files but at status at the bottom I am able to see 1000 files loaded. When I add a folder containing opus files I am unable to see anything. I have copied the mediainfo folder to program files which is extracted and added path to system settings.Can you suggest how to configure mediainfo in playtime app.

Regards,
Rupesh.

Hi, rupeshforu3, and welcome to the DonationCoder site.

That's odd.  You should see something like this:

You need to add the opus extension to the audio extension list like this:

rupeshforu3:
I have followed your suggestions and added opus in audio codecs section and at present the app is able to load files but it is showing 0 in all fields of all files.

When I export the content to csv file and when I open the file in Microsoft office excel only the file name and file path are occupying the whole row of the corresponding file and so there are no other options like size, play back length etc.,

Would you please post a screenshot of what you're seeing?

CWuestefeld:
I believe you can get to what you're trying to do by using XYplorer (the Windows Explorer replacement). This has a means of adding to the displayed file list various file attributes, including what it can pull from ID3 tags of audio files, or EXIF tags in images. Once you've got them displayed with the track length, there's a function for outputting the directory list as a "report" into a file. So if you do this for both directories, using the same sort sequence, and then diff the two files (using a tool like WinMerge).

One possible hole in this is that I'm not sure if it's able to read opus files.
