Hints of New Things from Zebranalogic

There are a couple of posts up on the Zebranalogic blog discussing some of what they are working on. First is Digital Audio Techniques. "In our research of audio development, we are working with some digital techniques for digital systems. Like the Direct Digital Synthesis (DDS) technique. With this one we can simulate analog waveform with a dsp processor. The result is pretty good and depends of the number of digital samples. The output is ploted in a GLCD (Graphic LCD ). The frequency of the wavform is variable by software with a knob..."

The second post is New MIDI design which mentions, "In order to complete our blocks for a new audio machine we are designing a more complete MIDI circuit. Part of the process is the system simulation. In the picture we can see the capture of the values of Status byte, note, velocity and note off, all are the same in this test because we are entering the values with a PC keyboard ...we are working a lot to design a bigger machine with more details and best options..."
