Hi,

I have ACL10 then I jumped to ACL2013 which is version 19. I suggest that you read carefully through all of the Mastering parts in the manual.

The ACL2013 manual says this as an overview:

You will find the following effects modules here: "StereoFX", "Equalizer", "Brilliance",
"Sound Cloner", "Dynamics", "Multimax", "Reverb / Echo", "Energizer" and "Chorus".
The functionality of the optimization effects is the same in principle: Adjust the
strength of the effect via the slider, switch the effect on and off to compare the
original with the edited audio material and access the actual operation console by
clicking on the symbol in the bottom right-hand corner.

There is more detail on each of the effects further on in the manual. Basicaslly, you do what they say. Try out each and listen to the effect, select and modify the presets until you get a sound that satisfies you. You do not need to turn on all of them or any of them. It all depends on your source material and what you are looking for in the way of sound. Once you play with all of the tools, then you will better understand what they do and how to use them, when and why.

I don't know if they have this in your version, but there is an Info button with an arrow on it at the right side of the screen just above the tools. With this open there is more informatiion given on each of the tools when you click on the tool.

You may find some information useful by looking at Kraznet on YouTube. He has done over 150 tutorials about (Magix) Samplitude Pro, some of which are about cleaning and mastering and there are similarities.

Whilst doing the above, take notes.

When you are sufficiently proficient, then maybe you can do a tutorial or a series of tutorials on Mastering.

Word of warning: the current version is ACL2014, but do not purchase it as it is really a downgrade. They have the higher level Audio & Music Lab2014 Premium which is much better and a step up, with some interesting new effects. If you are planning to upgrade this would be the best, otherwise stay with what you have.

Here is what the AML2014 Premium manual says about Mastering at the summary levels:

So that your recordings sound optimal, a selection of mastering tools are available to
you once you have cleaned up the audio material. Try them out yourself to see which
settings are the best, or let MAGIX Audio & Music Lab 2014 Premium do the work for
you by searching for the best settings automatically. For more detailed information
about the tools, please read MAGIX Audio & Music Lab 2014 Premium's help file.

"Mastering" is the second effects area and is meant for optimizing audio material. For
example, you can increase the loudness of the music (Multimax), copy the sound
characteristics of a particular musical style (Sound Cloner (view page 71)) or sonically
"freshen up" old MP3s with a low bit rate (Brilliance Enhancer (view page 71)).

The mastering functions are activated in the Mastering section. Mastering effects are
used for either improvement or a dedicated change of the sound of the audio. All
mastering effects function in realtime which means that you can switch them on and
off and change their parameters during playback and listen to the result of the
changes immediately.

There is a feature not available in lower level versions:

"Mastering" is the second effects area and is meant for optimizing audio material. For

MAGIX Audio & Music Lab 2014 Premium analyzes the audio material in the project.
The settings that are used to achieve the optimal sound for a particular musical style
depend on the audio properties of the source material. If the audio material in all the
objects is from the same source and are similar enough in sound, the wizard will apply
the appropriate effects at the project level. If the objects are not similar enough, the
effects will applied to each object separately. Audio & Music Lab automatically
decides whether the Auto Mastering will be applied to individual objects or to the
entire project.

The results of the Auto Mastering process can be checked in the dialog that follows.
You can play back the object under the position line either with effects (result) or
without effects (original). The "Back" option can be used to select a different musical
style. If you are satisfied with the results, you can click on "Apply" to close the Auto
Mastering wizard and finalize the process including the effects. To close the wizard
and return all the settings to their original values, click on "Cancel".
