This page contains only DSP related SynthEdit modules (SEMs). The algorithms are tweaked to deliver the best performance as possible. This means that many parameters are not tweakable via pins. However, the important parameters can be, even if this sometimes means compromises in the performance. In this case the module is available twice.
\nAll modules that can be found here have been taken from my open source project ‘Delphi ASIO & VST’<\/a>. Feel free to download the original source code and experiment with it.
\nDespite being open source, the modules are currently not maintained any more.
\n
\nThe files are packed using 7z<\/a>. Visit the homepage to download a free tool to extract the archives.

All DSP Modules<\/h4>\n

All modules that can be found below are bundled into one large SE module containing about 175 sub-modules. There are no examples included, but it can be useful for replacing several single modules by one large module as this module saves space due to common use of the code. It is updated less often then the other modules, but feel free to contact me if something is missing for your needs.

Audio To RGB Converter<\/h4>\n

\"Audio
\nA very crazy idea to convert audio into an RGB value came into my mind, while working with the whole polyphase filter stuff. It’s far away from beeing sophisticated rocket science, but it is fun to play with this tools nevertheless. An example is included as well.

Barberpole Flanger<\/h4>\n

\"Barberpole\"
\nA “Barberpole” flanger implementation with up to 16 stages (more on request). The crossfade algorithm isn’t perfect yet, but this creates an interesting pitchshift effect, so I left it in.

Butterworth LP & HP Filters<\/h4>\n

\"\"<\/a>
\nButterworth LP & HP filters (up to 64th order = 384dB\/Oct). These filters are supposed to be used as static filters, but a special “automatable+” version is included as well, which allows to perform frequency modulations while maintaining a low CPU usage. The filter order may only be used statically though.<\/p>\n

Dither & Noiseshaper<\/h4>\n

\"SEM
\nA Dither & Noiseshaper implementation with a fast gaussian dither and some unique noise shaping filters. The module is designed to run at 44100 Hz. The reason for this is, that the filters have to be recalculated for each sampling rate and I currently only did this for the 44.1 kHz case. If you consider using this module and you need other sampling rates as well, feel free to contact me.<\/p>\n

Convolution<\/h4>\n

\"\"<\/a>
\nA convolution module for SynthEdit. Select a wave file with an impulse response, connect input and output and optionally choose the desired latency. The freely available code is entirely based on unoptimized open source code. It’s a bit slow, but free to use.
\nA faster version using the Intel Performance Primitives is available. In the current version it is between up to 10x faster (if you allow some latency). That version can be licensed for 99,90\u00e2\u201a\u00ac. A demo version is available here<\/a>.<\/p>\n

\nThis SE module contains 19 different dynamic processors (gates, limiters, compressors), that can be found in the Delphi ASIO & VST open source package. On request all these processors can be modified to support a sidechain input and more than one input\/output channel for more complex settings.<\/p>\n

Basic Filters<\/h4>\n

\"sem-filters\"
\nThe module contains 8 different types of biquad filters. You can find all the standard filters (lowpass, highpass, bandpass, notch, allpass, low shelf, high shelf, peak) in here. Furthermore I added a filter featuring a universal shape control. This can change the filter type continously between lowcut, low shelf, peak, high shelf and high cut. It was part of my KVR Developer Chalenge entry of 2007.<\/p>\n
