JamesDSP Manager is an open source audio DSP (digital signal processor) for Android. In this article, we’ll not only explore its features but will also see how we can enable and configure JamesDSP Manager properly to get the best audio output. It’s a great open source audio manager and equalizer for Android. Learn how to set up and configure JamesDSP Manager and explore its features.
The list of software Audio Digital Signal Processors (DSP) on Android is big and still growing. Most vendors usually ship their flagship devices with licensed DSP libraries which provide exceptional audio quality. Several of these manufacturer-specific audio DSPs like Dolby ATMOS and AM3D’S Zirene have been ported by talented developers to almost all Android platforms. Some of them require big modifications to the Android Frameworks to run properly.
A new open source audio DSP has been around for some time, known as JamesDSP Manager. It implements the most basic and some interesting advanced audio features. Also, it supports most ROMs (tested on Samsung ROMs, AOSP, CyanogenMod, LineageOS) and Android versions 5.x and newer. JamesDSP Manager can be easily installed by flashing a zip file through recovery. The author releases ZIPs for both ARM and x86 architectures.
