Audio Evolution can store all your sample arrangements, mixer settings and options in something called a 'Project' file. From starting up Audio Evolution, everything is related to the current 'project'. When you did not load or save a project yet, you are using the 'Untitled' project. Although this is convenient because you can immediately start looking around and trying out Audio Evolution Mobile, we suggest you make a habit of starting a new project when you start working on something serious. In this way, all the samples that are related to your project will be in one place: the Samples subdirectory of your project. Press the top-left Project icon and choose the 'New Project' option to create a new project folder with a name of your liking.
Note: some characters are not allowed, so it's best to stick with normal alphabetic characters and numbers. You will get an error when a project name is not accepted. Some devices also do not take spaces, so we advise against using those as well.
At first start-up, an AudioEvolution folder is created on your device. The structure is as follows:
/mnt/sdcard/AudioEvolution /mnt/sdcard/AudioEvolution/Projects /mnt/sdcard/AudioEvolution/Projects/MyNewProject/ /mnt/sdcard/AudioEvolution/Projects/MyNewProject/Recordings /mnt/sdcard/AudioEvolution/Projects/MyNewProject/Samples /mnt/sdcard/AudioEvolution/Projects/MyNewProject/Samples/Track1_001.wav /mnt/sdcard/AudioEvolution/Projects/MyNewProject/Samples/Track2_001.wav /mnt/sdcard/AudioEvolution/Projects/MyNewProject/Var /mnt/sdcard/AudioEvolution/Projects/MyNewProject/MyNewProject.prj /mnt/sdcard/AudioEvolution/Projects/MyNewProject/OtherProject.prj /mnt/sdcard/AudioEvolution/Projects/MyNewProject/TempProject.prj /mnt/sdcard/AudioEvolution/Projects/Untitled/ /mnt/sdcard/AudioEvolution/Projects/Untitled/Recordings /mnt/sdcard/AudioEvolution/Projects/Untitled/Samples /mnt/sdcard/AudioEvolution/Projects/Untitled/Var /mnt/sdcard/AudioEvolution/Projects/Untitled/Untitled.prj /mnt/sdcard/AudioEvolution/Projects/Untitled/TempProject.prj etc.
Note that in this example, there are two project folders: MyNewProject and Untitled. In each project folder, there can be multiple project files (ending in .prj). You could for instance save multiple mixes of the same project in multiple project files, but they would still belong to the same song/project.
The only subdirectory you should be further aware of is the 'Samples' subdirectory. Here, your recordings and imported samples eventually end up. If you want to transfer audio files from your desktop to your Android device for use with Audio Evolution Mobile, it's best to copy them here.
