FM ENCODER STEREO INSTALLATION GENERATOR

Sinus generator works faster and more accurate.

FM ENCODER STEREO INSTALLATION PRO

Operating system Windows XP pro with service This program has been tested on a Pentium III 600 MHz. If you hear drop outs, increase the buffer size. The input signal so that the Input Peak level meters reaches a average of 90%.Īdjust the Master volume and the Wave volume on the mix consoleįrom the Output device to maximum. Switch on the clipper and the 15 kHz low cut filter. Do not combine the left and the right channel. By pressing this button, the stereo coder will do his job.Ĭonnect only 1 output channel from you soundcard to the input of the This happens because the 19 kHz pilot tone will always When there is no input signal, the Output peak will still showĪ peak of 8%. Volume of the input signal to an average of 90% on the input peak meters. Then the volume of the input signal has to be lowered. The Output peak shows every second the highest output signal. The Output peak is to watch if the signal will not be distorted. It’sĪlso possible to use the 38 kHz controller as a stereo widenerīy shifting him above the 100%. So that an optimal stereo separation can be reached. The amplitude of the 38 kHz signal can be controlled manually, Use the clipper and the 15 kHz low cut filter to stay within the Stokke mask. The 15 kHz low pass filter will take care that frequencies above

If you use the clipper, my advice is to also use the 15 kHz low pass filter. Because it works after the pre-emphasis, it will mostly cut the high frequencies so there will be no notable distortion heard. The clipper can be used after the pre-emphasis. The American standard uses 75 micro seconds. The European standard uses 50 micro seconds. The pre-emphasis can be switched between 50 and 75 micro seconds. Try to make the Buffer size as small as possible, to keep the latency low.Īlso the pre-emphasis, clipper and 15 kHz low pass filter can be switched You configure the record configuration well (the soundcard mustĪdjust the Buffer size. The same soundcardĬan be used as Input and Output device. SelectĪ soundcard for the Input and Output device. Operating system: Windows XP with Service Pack 1Īfter the program started up, you see a window like above. Soundcard: at least a samplerate of 192 kHz. Soundcards, share it with us by using the contact form. But the new SoundBlaster soundcardsĬan probably do this job too. Most of them can handle the surround 7.1 system. There are a few soundcards who can handle a samplerate of 192 kHz. Little latency between the input and output signal. Stereo signal will be generated and a good stereo separation will The stereo signal will be calculated digital, so that a perfect

Will be edited fully digital, so there is no loss in quality Windows XP WITH Service pack 1 is the first Windows version whichīy using a media player on the same computer, the audio-signal Most operating systems can not handle a samplerate of 192 kHz. These soundcards can produce frequencies up to 96 kHz.įor a frequency of 96 kHz you will need a minimum samplerate of Nowadays there are cheap soundcards which have a samplerate So you need a soundcard that can handle a minimum frequency ofĥ3 kHz. The maximum frequency of a MPX stereo signal goes up to 53 kHz. The stereoĮncoder is a simple application that runs with Windows XP with service To generate a stereo signal for FM radio transmitters. This project makes it possible to use a “normal” soundcard
