Mediapurge is a free media management system for audio , video files and image files for the Windows 7 , Windows 8 , Windows 10 , Windows Server from 2008 R2 and Linux operating systems . The program has specialized in the duplicate search with the help of acoustic fingerprints and optical fingerprints for large amounts of data, but also supports common tag editor functions with the support of metadata .

The responsible developer is Peter Lorenz.

Range of functions

For the duplicate search using acoustic fingerprints, Mediapurge supports all common audio, video and image formats, optionally with an internal or external decoder .

All common tag formats, including ID3 (ID3v1 / ID3v2), Vorbis comment for FLAC and Ogg Vorbis , WMA , as well as metadata from RIFF-WAVE files are supported for the functions for tidying up the media inventory.

The program has a wizard-based interface in German and English, which guides you through each function in a uniform scheme. In addition to the duplicate search, the program can also automatically convert media files, sort them on the data carriers, edit metadata and compare stocks. Parameter entries were deliberately avoided in order to make the working environment as simple as possible, which in turn limits the scope of functions to the options provided.

history

Mediapurge based on MP3Find (cleanup functions 1999-2011), but was completely re implemented . The general scope of functions as well as the algorithm already contained in MP3Find for the creation of acoustic fingerprints and the integrated database for processing large amounts of data were conceptually adopted and further developed.

The development of Mediapurge began in 2010 with the idea of ​​creating easy-to-use software for the most frequently required functions for maintaining large media collections. The first version of the program was published in February 2011. The versioning was continued, whereby Mediapurge started with the main version 5 after several preliminary versions .

From 2013 to 2014 a compiler change to a Unicode compatible compiler was carried out; In the course of this change, most of the processing routines were inevitably rewritten. In addition to many small improvements in 2015, additional formats such as Opus and WebM were added in 2016 , and FLAC support was expanded. The working environment supported as of this date German and English. In 2017, memory support up to the 4 GB limit (under Windows 7 or Windows Server 2008 R2) was activated and the handling of large files was improved.

A native version for Linux- based operating systems such as Ubuntu , Redhat , Suse has been available for download on the website since 2018 . For the Windows 10 operating system, Mediapurge can also be downloaded from the manufacturer's website in the Windows Store .

From version 6.5, track recognition is possible via the local music database. The official support of images was then also added in 2019 with version 6.6. A method is available for the duplicate search of image files, which works with fingerprints in a similar way to the processing of audio files.

In December 2019 there was a major rollout of all programs, which essentially resulted from an internal quality audit and, at least for Mediapurge, did not produce much new functionality. Also in the same month was the 20th anniversary of the common code base which began in December 1999 with MP3Find.

After the articles in the magazines LinuxUser and LinuxMagazin pointed out some initial weaknesses in the new image recognition algorithm, it was improved once again in order to actually only find image duplicates in the default setting. It is still possible to recognize very similar image motifs; for this purpose, the software offers the possibility of reducing the comparison accuracy and making suggestions for settings depending on the area of ​​application. The new image recognition was rolled out for Windows and Linux users in early 2020.

The expansion to include a web-based database for the automatic completion of meta information, which was also announced in early 2020, will not find its way into a Mediapurge for the time being, but instead implemented in a separate product called TagComplete, which is based on Mediapurge technology.

technology

The duplicate detection of Mediapurge based on a proprietary technology, the MAFP (MAFP, m p3find a coustic f inger print) which was developed primarily for for this purpose may be also used for the title ID. The processing libraries are divided into the areas of title recognition ( decoder , analysis algorithms) and title identification (comparison algorithms, database ). The acoustic fingerprints themselves consist of a two-part key pair that reflects the features of the audio profile that are significant for recognition. The key length varies depending on the track length, it is possible to identify incomplete music profiles with the help of the MAFP.

For the use of the technology in the processing of library was TagComplete to functionality for remote replication , and data comparison means web extended.

The source code of the processing library and the specification of the web service - TagComplete API V1 - are not freely accessible.
