Audio Library Manager

About This Guide

This application note describes the usage of Audio Library Manager Tool alongside Audio Weaver Designer and demonstrates its uses. It is an application with a GUI to easily create wave flash file systems that contain audio files to be played on a target hardware or to be tested on a native target. This is a standalone application and is independent of any underlying software to create the Binary file. This is an upgrade from the previous ‘Wave Library Generator’ as it now both generates binary as well as extracts files from a binary.

Download the Audio Library Manager 2.1.0 here. Audio Library Manager_2.1.0_Installer.exe

The output generated from the tool consists of a Binary file (.bin) with the selected wav/Ogg files along with an encoded U32 list of the file names in the order added in the tool window as .csv. This .csv file is used to load into the TableSource module for Index mapping. The generated txt file contains a list of the included audio files and is solely for documentation purposes.
