General Help and FAQ



WiFi Speaker Guide

This will walk you through how to install and troubleshoot WiFi Speakers.

Setup:
First, download the server. Install the server on your Windows media PC. After installation, download and install the Android client from Google Play on your android device. Start the WiFi speakers app on your android device. Start the server application on your Windows media PC.

Connecting:
Within the WiFi Speaker Android application there should be a search button. Click this button to auto-find servers on your local network. If none are listed at first, try again after about 10 seconds. A list should display your server's IP address. Select the server in this list, then press the connect button. The Android device is now connected to the server.

Decreasing Latency:
4 things affect latency; server buffering, client buffering, audio format, and audio compression. Try adjusting the app's buffer time first. This will increase the likely hood of breaks in audio, but will reduce latency. If you are running locally you will probably be able to set this to zero. Next adjust the server's buffer time. You'll find this option in the server's settings under the Audio section. Lastly, select a smaller audio format. This will reduce the size of the audio being sent. If you have the pay version of the WiFi Speaker app, enabling audio compression will further reduce audio size.

Crashing or bugs? Other questions?
Please contact the developer. Bugs will be fixed quickly, and all feedback is welcome!



Troubleshooting
Can't connect?
If the Android device fails to connect to the server, please ensure the server's firewall allows TCP connections on the server's port. The server's default port is 57005, but this can be changed in the server's settings.

No Audio?
If there is no audio playing from the Android device, please check the Android device's media volume. Next, check your server's volume. Lastly, check that the device you wish to capture from is selected, and that the server's graphic equalizer is displaying activity. If all these options check out, try shutting down the app and server, and starting again. If this continues to be an issue, please contact the developer.


FAQ
  1. Does WiFi Speaker work over 3G/4G?
  2. Yes, it does! Purchase the paid version for 90% audio compression to reduce data consumption. Purchasing the app is not necessary for it to function over 3G/4G networks. See the help screen in WiFi Speaker server for required upload and download bandwidth.

  3. What kind of latency can I expect?
  4. Average minimum latency is 0.01 seconds (or 10 milliseconds) locally.
    Of course latency on any network will depend on topology, activity, desired buffer time, and audio format, as well as the server's and Android device's processing power, and CPU load.


  5. What audio formats does WiFi Speaker support?
  6. WiFi Speaker supports linear PCM sampling rates of 8khz, 11khz, 12khz, 16khz, 22khz, 24khz, 32khz, or 44.1khz, with a sample sizes of 8 or 16 bits, in Mono or Stereo. WiFi Speaker also has GSM encoded linear PCM audio available in the paid version.

  7. How do I configure my server?
  8. All configuration is done in the settings screen. Look for a button with a wrench and screwdriver. If you need any help with configuration, contact the developer and we'll sort it out!

  9. I can't connect to the Server?
  10. Try disabling your firewall entirely. If you can connect, then you need to add a firewall exception for the server's port. Also ensure the IP you're inputing into the Android app is on the same subnet as the Android device. If you'd like to see the media server's IP4 information for a specific network, see the Display option in the server's settings.

  11. Auto-discover feature not working?
  12. The auto-discover feature relies on cross-subnet UDP broadcasts. Some routers do not allow these type of broadcasts, or have them disabled by default. If UDP broadcasts are impossible, you must input the IP address of your media server manually.

  13. I hear breaks in my audio? My audio sounds too fast or too slow?
  14. If you hear breaks in audio, or it sounds like its playing too quickly, try selecting a smaller audio format, and/or increasing buffer length. Lastly, just try restarting the application.

  15. My audio sounds distorted? There's a lot of static in my audio?
  16. Try changing your audio input device. Sometimes the default device will be a built in microphone instead of the 'What U Hear' audio input device. If this is the case, click the Settings button in the server app, click the 'Sound', and select 'What U Hear' from the drop down. If you don't see the 'What U Here' option, your computer may not support the 'What U Here' interface.

  17. Can I run the server on Mac or Linux?
  18. No. The media server must be Windows XP, Vista, or 7. Windows 8 has not been tested. If enough requests are made, a Mac/Linux Server may be developed in the future.

  19. Can I run a PC client on Mac or Linux?
  20. Yes! Through an android emulator the Android WiFi Speaker client can run on Mac or Linux. A native Mac/Linux client is being developed.
