Sometimes you feel, the sound quality of your device’s external speaker is not that good. If you own latest Samsung device, then Group Play will allow you to sync multiple Samsung devices. What if you own non Samsung Android device? Thanks to an XDA developer jekatt for introducing an app called “SoundSeeder”. The app was developed with the core concept of Group Play, which allows you to share music playing on one device on other. SoundSeeder will work on any Android device that runs 4.1 or newer and lets you share music to any Android device running 2.2+ operating system. SoundSeeder works via WiFi connection, allowing you to connect up to 16 different devices and also lets you control playback and volume on all devices.
Here are the features of the app,
Fully featured Music Player (Play, Shuffle, Repeat, Queue, Playlists, …)
Support for mp3, mp4, m4a, aac, 3gp, ogg, flac
Media Library sorted by Album, Artist, Title, Folder, Genre, Playlists
Autodiscovery of SoundSeeder Player / Speaker via WiFi
Music streaming in sync without delay
Support for Androids portable hotspot to connect devices wherever you want
Home screen and lock screen widgets
If you face any problem with WiFi disconnection when the device goes to sleep, then checkout this original thread on XDA for support.
