Splitting MP3 files

In order to split MP3 files, they must first be converted back into "normal" audio data. For that, you'll need the add-on pack "More tracks and formats" or a Music Maker Edition such as MUSIC MAKER Premium. Both can be purchased and activated directly in the program's in-app Store.

For the add-on, proceed as follows:

• Open the "Store" top right.
• Select the "Features" option from the dropdown menu.
• Search for "More tracks and formats" or scroll down the list of items.
• Click on the "More tracks and formats" tile to read more detailed information.

• Click on the price to to buy the add-on and follow the instructions.

Afterwards, in addition to the WAV, WMA and OGG export formats already included in Music Maker Free, you also have unlimited access to the fee-based MP3 and FLAC encoders. This means that you can now load and edit all MP3 files, as well as create them from other audio formats. You also now have an unlimited number of tracks in the project window.

Here's how to import your own MP3 file into the program:

• Click the icon for the File manager in the upper toolbar. This will open the File manager on the right.
• In the file manager, go to the folder where your MP3 files are located.
• Drag & drop the MP3 file into the arranger on the left. You can place several MP3 files there in a row.
• If required, zoom in using the zoom buttons in the lower right so that you can see all the media in the arranger.

You can drag your MP3 files anywhere onto any track. In general, it makes the most sense to drag the first MP3 file directly to the beginning of track 1 and place all the others to the right of it, leaving a bit of a gap between them.

• Press the spacebar to play or pause playback.
• Click in the timeline to move the playback marker. This allows you to jump to different position.

The yellow range above the top track is the section that is played.

• To change the range, drag the ends of the bar to the left or right with the mouse. You can also move the ends with a simple click in the range bar: Left-clicking sets the start of the range, right-clicking sets the end of the range.
• The yellow playback range can also be shifted freely. To do this, click in the middle of the area and drag the range to the left or right over another part of the project, for example over another MP3 file in the timeline.

All MP3 files in the project can be split using the same easy method:

• Move the playback marker to the place where you want to split the file and press the "T" key.

This cuts the object in the track into two separate objects.

To delete a certain section in the middle of the MP3 file, cut the file once at the start and again at the end, and then simply delete the part using the Del key.

Good to know: All MP3 file editing with Music Maker is non-destructive, which means that your original MP3s remain untouched.

To cut the MP3 file at its ends, proceed as follows:

• Move the mouse pointer to the front or back edge of the object until the mouse pointer becomes a double arrow.
• Click and drag the object edge inwards.

This allows you to cut out unnecessary parts at the beginning and end.

You can fade two objects into each other by applying a crossfade with the object handles:

• Move the rear object onto its own track below and drag it forward so that the start overlaps with the end of the first MP3 file.
• Click the object above to select it.

Now, handles will appear on the object.

• Drag the handle at the back object edge to the left. This will create a fade-out.
• Click the bottom object and drag its front handle to the right. This creates a fade-in.

Alternatively, you can merge the two objects on the same track to create a crossfade. But it's also possible to adjust the crossfade more precisely if the two objects are placed on two different tracks.

• Play the transition and listen to the result. If necessary, adjust the position of the objects on the tracks and the fade handles until you get the result you want.

Want to enhance the audio of your MP3?

• Click on the FX button in the upper toolbar to open the Object effects.

The object effects will then display below on your interface. Effects are always applied to the object that is selected in the track. You can use the equalizer to give dull recordings more excitement and intensity. Use the compressor to increase loudness and punch.

• Use the mixer to balance the volume of MP3s on different tracks. Open this by pressing the "M" key or by clicking the mixer icon in the toolbar.

You can find additional track effects for all the objects in a track and a mastering section for overall sound in the mixer as well..

In some cases, you may want to reduce or increase the volume of certain parts of an MP3 file. This can be done using a volume curve.

• Right-click on an empty area and select "Display track curves" > "Volume".
• Zoom into the display if necessary and place curve handles by double-clicking on the volume curve.
• Drag the curve downwards using the handles.

To make a specified range louder, do the opposite and make all the other ranges quieter using the volume curve. This helps prevent clipping.

The mixer also lets you control the overall volume of each track. This lets you achieve a harmonious volume balance across several objects in the arranger.

Finally, when you play your MP3 file and everything sounds the way you want it to, you can export your project. You have the choice between exporting the complete project from the first to the last object or only the current playback range.

If you only want to export a specific area, make sure that the playback range is exactly over that part of the project. If you have several MP3 files, it's usually best to export each MP3 file separately and then move the playback range to the next MP3 file in sequence.  

To export, open the "File" menu and select an option from the "Export" submenu. The following audio formats are available for compressing files:

• Audio as MP3: With this option you get back the MP3 files containing all cuts and edits made during the project.
• Audio as Ogg Vorbis: OGG has (almost) the same properties as MP3. The main advantage of this format is that it is available for free. That means this option is also available for use without the additional package "More tracks and formats".
• Audio as Windows Media Audio: WMA files are also free. This codec was developed by Microsoft and is included with your Windows operating system.
• Audio as FLAC: This format is the only truly lossless compression format (aside from WAV). This means it offers the highest sound quality. Even for formats with quality loss, like MP3 and OGG, settings can be adjusted so that you don't notice any quality loss or artifacts in the sound. Like MP3, FLAC requires the purchase of the "More Tracks and Formats" add-on pack or a Music Maker Edition.

Whatever format you choose, there is an export dialog where you can change the compression settings.

• If you only want to export the current playback range instead of the complete project, be sure to select the "Only export the area between the start and end markers" option in the export dialog.
• Click "OK" and select a target directory where you want to save your files.

This is where you will find your export files and then copy them to your smartphone, for example.
