Lexis Audio Editor is a good solution available for those looking to perform audio editing straight on their Android device. Thanks to its friendly user interface you can easily load files having the following formats: AAC, MP4, WMA, MP3, and few others. As soon as a song is loaded, the app will generate a waveform allowing you to quickly set starting and ending points for your selection.
Another handy feature is the integrated 10 band equalizer which can be used to change the sound of your audio file a bit, and make it sound kinda different. Moreover, you can use Lexis Audio Editor to mix the current audio file with another another file. The interface also provides commands for performing other tasks, such as starting the recording process, pausing, or stopping.
In case you want to save your project in the MP3 format, you should know that this action can be done only if you have the paid version of this software.
