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

[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.

I heard that xyplorer has more options to view properties of multimedia files and so can you give suggestions according to my needs.

Regards,
Rupesh.

Open both panes (F10)
Open the source folder on the left / upper
Open the destination folder on the right / lower
Make sure the left / upper is the active pane

Menu - Panes - Sync Select...
Select Uniques
Now all files selected on the active pane are the ones that weren't transcoded

Upload to an external file hoster and link it here:
- One sample of a source folder file (a small one!) for each file type
- The corresponding files from the destination folder
Zip each samples into a file named either source.zip / destination.zip please...

Can you suggest just how to calculate the total playback length of a folder which contains suppose 500 audio files organized into various sub directories.

My source folder consists of mp3 files and the destination folder consists of opus files. Is it possible to sync both directories ignoring types of files and considering only filenames without extension.

Via a script

My source folder consists of mp3 files and the destination folder consists of opus files. Is it possible to sync both directories ignoring types of files and considering only filenames without extension

See my last post?
Only difference: Use [x] Ignore extensions in the Sync Select... Window

Ok it is possible to sync my source and destination folders. As I am new to scripting and to xyplorer can you provide the script to calculate the total playback length of a folder.
