The dedicated NGF Vocoder Project website is now online. It can be found here. The NGF Vocoder Analyzer Site is updated. It can be found here with updated schematics and downloads for the documentation.

Vocoder : Analyzer
The analyzer part of a vocoder has the function to divide the incoming signal into frequency bands and to generate an analog output signal per band in dependency to the signal level.
Because i wanted to be flexible what filter architecture and frequency distribution to use, i made the filters pluggable. So you can easily change filters and test different configurations. For the first attempt i used the filter architecture suggested by Jürgen Haible who derived them from the EMS 5000 vocoder. Other filters will follow. I added four more filters and moved the frequency of the high- and low pass.
