Converting Music Files (Audios)

Multimedia Xpert can convert between a massive number of audio formats. It can be viewed as the universal audio converter. If your player can't play an audio, no problem, Multimedia Xpert can fix that.

At this time it supports

• 300 input file formats
• 161 output file formats
• 244 audio codecs

and the numbers are constantly growing. What is most important: The algorithms are reliable! Here are some frequently used conversions:

• Conversion of Flac to MP3 (Lossless audio coding)
• Conversion of AAC to MP3 (Advanced Audio Coding)
• Conversion of ALAC to M4A (Apple Lossless)
• Conversion of EAC to AAC (Exact Audio Copy)
• Conversion of M4A to MP3 (MP4 AAC, ie. produced by the Android app 'Voice Recorder')
• Conversion of WMA to MP3 (Windows Media Audio)

Multimedia Xpert is near to converting anything to anything correctly. It can be extremely frustrating if you can't hear something or just get an error message after a long processing. Also, not everybody would like to install a different converter for each single audio format whereas there exists a program which can do it all, and with high reliability.

Mass conversion

Multimedia Xpert is specifically designed to convert many files in a single pass without user input. As a specialty, it can also convert files directly in place. More info about that in overwrite management.

Making file sizes smaller

A conversion can be used for making file sizes smaller to bring down upload/download times. To achieve this you can reduce the bit rate of the audio.

Repairing partially damaged files

Sometimes audio files get damaged during the transfer or transport by USB stick or other medium. If the damages are not too big there is a good chance that a music file can be repaired. Just convert it to the same format. The conversion algorithms are quite tolerant and will recover whatever possible. You will end up with a file that has some parts skipped but at least it's a fully valid one which can be played by every music player without any problems. Multimedia Xpert simplifies such conversions by a built-in Inplace Replacement method that doesn't require entering a new name.

Selecting and/or adding streams

In the past streams were called "tracks", but today the word stream is more common. During the conversion, you have the option to pick some streams/tracks from the input and at the same time add new ones (). To just add some streams to the audio without converting please read here.

Clipping audio

Sometimes you would like to remove a part on the start or end. You can do this by switching to the Output Specification page and entering an extraction range.

Listening to the converted media

After a conversion the green buttons in the grid will perform some functions on the converted output. We recommend VideoLAN Client (VLC) as a player because it can play nearly any format and is a free and open community solution. Here some tips for VLC:

• You can stop the opening of its main window on a unsuitable location with an unfitting size by unchecking the checkbox "Resize interface to video size" in the section Interface.
  

Solutions for conversion problems

• If you hear only an inferior sound after a conversion, it is usually because no bitrate was specified in the specification. In this case, each codec selects its own bitrate. Unfortunately, in a few cases this value is much too low. This problem can be solved by entering something higher or equal than 160 in the Audio Bitrate field.
