FerricTDS - Tape Dynamics Simulator
Inspired by the smooth dynamic shaping capabilities of some high-end reel-to-reel tape recorders, this plug-in simulates three of the most distinctive and much appreciated sonic effects generated by these devices: Read More »

This short article gives a brief introduction on applying waveshaping algorithms not directly in the audio path but via a transformed equation through the sidechain and a VCA instead.

The concept of magnetic recording to a moving tape was invented by the German-Austrian engineer Fritz Pfleumer and received a patent back in 1928. The basic idea was to translate the voltage from the audio signal straight into magnetic energy, which then induces magnetic particles on a tape (moving along the inductor at constant speed). These particles manage to store the audio information. The whole process goes the other way around for recall.

While working on the Density overall re-design I was working extensively on the audio engine as well but just for one single reason: The one thing I was missing in the original design was to have some more “responsive” gain riding possibilities but without the usual tradeoff of introducing more distortion or compromising the transparency. And (unsurprisingly) that turned out to be not that easy.
Developers friend: the oscilloscope

Houston, we have a release date! The release of the Density mkII VST plug-in is now scheduled to end of this month. More specs and details will appear here during the next days or so – stay tuned. If you tend to react allergic concerning teasers better stay away a while from here

A short compendium on digital audio compression techniques.
Basic compressor configurations
Compression vs. limiting
Technically speaking the same principles are used in audio signal limiting and compression processors but just the transfer curves and envelope follower settings are different. Ultra fast attack rates and high ratio amounts are used for limiting purposes which causes just very few peaks to pass on a certain threshold.
In digital implementations limiting processors can be more strict due to look-ahead and clever gain prediction functions which guarantees that no peak information passes the threshold. That is called brickwall limiting then.

There were already an excursion here about the design of compressor transfer curves over here and now this article turns on to the design of the sidechain path of a compressor in general. One major part of the sidechain design of a compressor is the filtering and thats the topic here for now. Read More »
