1. The Basics
SoundSeeder turns your Android Smartphones into a wireless multi-speaker audio system.
Select and play music with SoundSeeder, connect additional devices as wireless speakers to your phone and listen to your music on all devices at the same time and in sync.
Use SoundSeeder to share your music with friends or even build an Android based wireless multi-room home audio system.
SoundSeeder requires a Wi-Fi connection to stream your Music to other devices.
You can use SoundSeeder with any available Wi-Fi Hotspot. If no Wi-Fi is available, create a mobile Wi-Fi network via “Wi-Fi Direct” or use Androids built-in portable Hotspot to connect your devices.
The usage of SoundSeeder is very easy:
- Connect your devices via Wi-Fi and start SoundSeeder.
- Choose one device to be the “Player” and set all the other devices to be “Speakers”.
- Select an audio file and start the playback on your player. All devices will start playing your music.
Start SoundSeeder and select the audio source of your choice:
- Play tracks that are located on your phone, in your dlna media library or in your google music account. See: My Music Mode
- Select one of 25.000 included Internet Radio Station and listen to it via SoundSeeder. See: Online Radio Mode
- DLNA Media Renderer (DMR) Mode – Control SoundSeeder remotely with a DLNA controller application of your choice. This mode enables soundseeder to play any external source that is supported by your dlna controller app. Read more…
- Microphone / AUX – Play sound that is recorded by the internal microphone or via the line-in (AUX) port of a connected USB soundcard. See: Mic/AUX Mode
- Connect to another SoundSeeder Music Player and play its music. This will switch your device to Speaker Mode
To connect a SoundSeeder device to another SoundSeeder Player, switch your device into “speaker mode” by activating the menu item “Player connection”:
Click on “Available Players” if you have multiple players in your network and to select one of it manually.
Soundseeder devices will discover each other automatically after they have been connected to the same Wi-Fi. If an device is not visible to your player, try to add it manually by entering its IP address. The IP address of your soundseeder device is displayed in the Settings (see Settings).
You can install and use SoundSeeder for free and as long as you want to.
In the free version of SoundSeeder some features are limited. You can unlock them by upgrading SoundSeeder via an In-App Purchase.
The benefits of the Premium Version are:
- Unlimited number of connected Speakers. (The free version is limited to max. 2 connected Speakers at the same time.)
- No connection timeout. (In the free version each Speaker connection is limited to 15mins.)
- No Banner Ads.
The Premium-Upgrade is bound to your Google-Account and will be available on all your devices. You don’t need to purchase SoundSeeder multiple times if you use it on multiple devices.
We have implemented two Android apps and one Java application, to provide SoundSeeder for as many devices as possible. Please note, that you need at least one device running Android 4.1+ to use SoundSeeder and that all devices need to be connected to the same (WiFi) network.
- The SoundSeeder Music Player is available for Phones and Tablets running Android 4.1 and higher (Jelly Bean, KitKat, Lollipop). Use this app to select and play your music or to connect it as wireless speaker to another SoundSeeder Music Player.
- If your device is running an older Android version (2.2 – 4.0), install the SoundSeeder Speaker App. It is a “Speaker-Only” version of SoundSeeder, which can be connected to the SoundSeeder Music Player App.
Both Apps are available on Google Play.
- The Java based Speaker Application lets you connect your Windows and Linux computers as SoundSeeder Speaker to your Android device. It requires a JavaSE 1.6 Runtime Environment and a WiFi connection to your Android device.
The Java Speaker is available in the Download Section.
The number of supported media formats depends on your device and Android version.
On most Android devices SoundSeeder supports the following audio codecs:
mp3, mp4, m4a, aac, 3gp, ogg, flac
Supported playlist formats are *.m3u, *.m3u8, *.pls and the internal playlists of Android.
This library represents your local music files, grouped by Albums, Artists, Songs, Folders, Genres and Playlists. It contains all audio files that were indexed by the Android OS in the external memory of your device.
Select any library entry to play it or to add the entry to your current playback queue.
To filter library entries, select the search icon in the top-right corner of the library view and enter the name of the Artist, Album, Song, … you are looking for.
This network browser lists all UPnP/DLNA capable media libraries in your WiFi network.
Select a media library and browse its content. All compatible audio and video files can be added to your playback queue.
If you like to select music that is located on your speaker devices, install an UPnP media library application (like BubbleUPnP or AirWire) on your speaker devices.
Note: This feature requires the Google Play Services installed on your device.
If the Google Play Services are available, you can access all your Google Music songs directly in SoundSeeder.
First of all select a Google account and start the import of your Google Music library into SoundSeeder.
After the import is completed you can browse and select your Google Music songs like locally stored media.
Activate the ‘Online Radio’ mode, to stream internet radio stations to your speakers.
SoundSeeder contains more than 25.000 Radio Stations, that are provided by http://www.dirble.com.
The stations are listed by favorites, countries and genres. Use the search field in the action bar to filter the items in the list.
The DLNA Renderer Mode is used to control SoundSeeder remotely via DLNA Controller apps.
DLNA is a standard technique for sharing digital media among multimedia devices. Is is supported by many apps, audio devices and media servers.
While the DLNA Renderer Mode is active, SoundSeeder can be controlled by any DLNA Controller app in your WiFi network.
Here are some suggestions for compatible DLNA application:

SoundSeeder is now also compatible with the application “AirAudio”.
On rooted devices AirAudio is able to capture the sound of any Android application and to stream it via DLNA.
Activate the DLNA Renderer Mode of SoundSeeder and connect AirAudio to SoundSeeder to stream your music to your speakers.
You can download AirAudio on Google Play. (free trial version) For more information check the description of AirAudio.
Select this mode to stream the microphone input or external usb audio sources via soundseeder.
By default soundseeder takes the input of the internal microphone and streams it to your connected speakers.
Note: To avoid audio feedbacks, turn off the speaker of your SoundSeeder Player device, while using the microphone.
SoundSeeder also supports the Android host mode for audio on compatible Android devices*.
If your device supports USB-Audio accessory, you can use soundseeder to stream external audio sources via the line-in (AUX) port of a connected USB soundcard.
*USB host mode needs to be supported by your hardware. USB-Audio is officially supported since Android 5.0 and proprietary supported by some vendors since Android 4.1. We have successfully tested soundseeder with soundcards based on the “C-Media” audio chipset.
Especially users of Nexus devices should see the article Record and play back audio using USB host mode for more information.
If the playback of Player and Speaker is not in sync when you run soundseeder for the first time, you can adjust the offset of your playback in steps of 10 milliseconds.
In Speaker Mode press the +/- Button in the bottom-left corner to adjust the offset.
The best way is, to start with offsets of -100ms and +100ms, to check in which direction you need to adjust your playback. Then adjust the playback in steps of 10 milliseconds, until its completely in sync.
Once the offset is adjusted, it will be saved for further connections.
Click the speakers button in the top actionbar to manage your connected speakers:

Auto pause: Activate this setting to pause the playback automatically, when no more speakers are connected.
Buffer Size: If the connection of your devices is unstable or not in sync, try to change the buffer size on player- and speaker side. A larger buffer reduces the probability of interruptions but requires more resources and might impair the synchronicity.
Google Music support: Deactivate this setting to disable the Google Music plugin and to hide the Google Music menu items. (See Google Music)
Maximum UPnP Download Rate: By default, the maximum download rate from UPnP media servers is limited to 2048kbit/s. The limited is set to increase the priority of the audio stream that is sent to your speakers. Changing this value might affect your speakers connection and playback quality while streaming media via UPnP.
Auto connect: If this setting is activated, the speaker will automatically be connected to your player, when it is started and gets discovered.
Auto re-sync strategy: Specify the automatic re-sync intensity for this speaker. The available options are off, low, medium, high and extrem and specify how fast (and often) soundseeder re-syncs the speakers playback automatically.

SoundSeeder supports scrobbling to LastFM via the following open source applications:
Please install one of these Applications to scrobble your music with SoundSeeder.
SoundSeeder is able to stream the sound of a Windows PCs via dlna. This feature allows you to stream music played from Spotify, Youtube or any other third party application to your SoundSeeder Speakers.
- Download and install the free application “Stream What You Hear” by Sebastien Warin on your Windows PC. It streams your system sound as mp3 stream via HTTP/DLNA: http://www.streamwhatyouhear.com/download
- Start “Stream what you hear” on your PC. Right-click on the tray icon and change the settings to:
MP3, 44100Hz, 16bit Stereo and 320kbit/s
- Now connect the PC and your Android device running SoundSeeder to the same (WiFi) network
- Start SoundSeeder and open the dlna network browser (“Add Track – Network”)
- You should now see the “Stream What You Hear” app listed as device. Select it and start the “MP3” audio stream.
SoundSeeder will now play your Windows PC sound.
Please note: The playback via SoundSeeder will be delayed by about 5s. The PC sound can be muted without disturbing the audio stream.
Each Speaker requires a constant Wi-Fi traffic of about 1.5Mbit/s (0.75Mbit/s in mono mode). Make sure that you have a solid Wi-Fi connection and that your Wi-Fi is fast enough to always ensure enough bandwidth.
You should also consider to use a dedicated portable HotSpot or “Wi-Fi direct” to connect your devices.
If the connection of SoundSeeder is instable, check the following options:
- Go to the SoundSeeder Settings and activate “Stay awake” to avoid the standby mode
- In your devices Wi-Fi Settings set “Keep Wi-Fi on during sleep” to “Always”
- In your devices Wi-Fi Settings deactivate “Wi-Fi optimization”
- Connect your device to the power adapter while using SoundSeeder to prevent standby mode
- Your Wi-Fi connection can also be affected by periodic Wi-Fi scans.
To reduce the number of Wi-Fi scans:
– Go to the advanced Wi-Fi Settings of your device and deactivate “Scanning always available”
To completely deactivate periodic Wi-Fi scans:
– Go to the Location Settings of your device and set the Location Mode to “Device only” or deactivate the Location Service completely
Devices made by different manufacturers and with different versions of Android might not be in-sync when you start SoundSeeder for the first time.
You can adjust the offset of your Speakers manually. On Speaker-side press the +/- Button in the top-right corner to adjust the offset of the speaker.
On Player-side the offset of each Speaker can be adjusted in the speaker management view.
If your connection has become asynchronous while listening to music, press the “SYNC” button to reset the connection. If this happens very often, please check the Wi-Fi signal strength and traffic load. Using a dedicated portable HotSpot or “Wi-Fi direct” might remove this problem.
Please note: Synced playback via Bluetooth speakers can not be guaranteed!
Bluetooth speakers use their own audio buffer, that adds an additional delay to your audio playback.
On most speakers this delay varies between 20ms and 70ms each time you start your playback. This means that the playback of your speakers can not be adjusted by adding a constant offset.
If you want to use SoundSeeder with external speakers, please connect them by wire to your line out.
If you have purchased the premium version of SoundSeeder, the number of connectable speakers is not limited. (See Free version vs. Premium version)
With a fast Wi-Fi connection (IEEE 802.11g+) you should be able to connect 16 Speakers (and more) without any problems.
Each Speaker requires a constant Wi-Fi traffic of about 1.5Mbit/s (0.75Mbit/s in mono mode).
If your speaker is not listed, please check if your Player and Speaker are connected to the same Wi-Fi. If your Wi-Fi network or your Android device does not support the autodiscovery of SoundSeeder, you can connect Players and Speakers manually with their IP address.
You can find the IP address of your device in the SoundSeeder settings dialog. (See Settings)
You can use Androids built-in portable Wi-Fi hotspot to connect your SoundSeeder devices wherever you want.
Select one device to be the hotspot. Go to the advanced Wi-Fi Settings of your phone (you can use the shortcut in SoundSeeder) and activate the portable hotspot feature.
Now all your other devices can connect to this hotspot and run SoundSeeder together.
To connect your SoundSeeder devices via Wi-Fi Direct go to your Android Wi-Fi Settings.
In the advanced settings menu select Wi-Fi Direct on every device you want to connect.
The next dialog shows all Wi-Fi Direct devices that have been found.
Select the devices you want to connect to, to invite them to your Wi-Fi Direct group. After the connection has been accepted by these devices they are connected and SoundSeeder is ready to use.
No, the connection of SoundSeeder devices via bluetooth is not supported.
SoundSeeder requires a fast network connection and supports the connection between mutliple devices. Wi-Fi offers the best performance to realize this.
SoundSeeder supports the Android host mode for audio on compatible Android devices.
If your device supports USB-Audio accessory, you can use soundseeder to stream external audio sources via the line-in (AUX) port of a connected USB soundcard. (See Mic/AUX Mode)
Please note: Your Android device has to support the “USB host mode” to use this feature. Please check your device specs. USB-Audio is officially supported since Android 5.0 and proprietary supported by some vendors since Android 4.1. We have successfully tested soundseeder with USB soundcards based on the “C-Media” audio chipset.
Especially users of Nexus devices should see the article Record and play back audio using USB host mode for more information.
