![]() If a sound card is reported to support 96 kHz or Stereo Tool cannot distinguish between 96 kHz capable sound cards and 192 Windows only reports if a sound card can handle 96 kHz or more. Make sure that the audio is playing through the selected sound card.Next, configure the things that you want to broadcast: Enable the Pre-emphasis setting for your area.On the receiver is turned on does not mean that the audio is reallyĬonnect the output to your FM transmitter, andĬheck on an FM receiver that the audio is really stereo.Ĭheck this by listening to the sound - the fact that the stereo indicator Stereo Tool should now be sending FM Stereo information in the output (Note: Make sure that some audio is playing before checking.) Also enable Pre-emphasize output.Ĭheck that no errors are reported in the Status overview at the left top If everything works fine, the status overview should look like this: Only continue if you can hear a stereo sound, otherwise check the bottom of this pageĬheck on an FM receiver that supports RDS that the RDS signal is really If the indicator is on, and the sound is still mono, theĪudio is apparently being resampled to 44.1 kHz. Note that "Probably OK" means just that: Stereo Tool is sending the data at the correct sample If the sound on the FM transmitter is mono or there is no RDS reception, it may be caused by If the sound on the FM transmitter is mono or there is no RDS reception But Windows or the sound card may still alter the sound, causing theįM Stereo and RDS signal to be deformed or lost. You are broadcasting too soft or too loud. ![]() Compare the volume of your sound with that of other stations. Too loud -> distortion disrupts the reception.) If the difference is big, that might be the problem (Too soft -> stereo signal is also too soft. Your sound card does not support the 192 kHz sample rate.See sound card requirements for a list of supported sound cards. The sound card output is being resampled to a lower sample rate by Windows.You might need to configure your sound card or Windows to output 192 kHz data. Windows may also start downsampling if another application was using the sound card when you opened the connection to it. Close any other application that is playing or recording audio, then disable and re-enable Direct Soundcard Access. If you have a Creative (SoundBlaster, X-Fi) sound card, it won't work. If you are experiencing hiccups in your Direct Soundcard Access output signal, please try the following steps: Otherwise, try if you can turn off any audio processing that is done on the sound card. With a larger buffer size, more data is sent to the sound card, so the chance that the sound card "starves" (has no more data to play) decreases. If that does not help, check the buffer indicator to see if the buffer is (almost) empty when hiccups occur. ![]() If the buffer slowly becomes empty, your processor might not be able to handle the processing. ![]()
