This is a AUv3 compatible audio compressor which can be used as plugin with your favourite DAW such as Cubasis, Meteor, Auria or GarageBand. It supports a modern graphical interface and presets with stereo meters for monitoring signal levels. An audio compressor is used to reduce the volume levels of loud sounds above a specified threshold and amplify quiet parts thus reducing an audio signals dynamic range. The dynamic volume changes of a recording means that the overall level of the compressed recording can be increased inside your mix. The recording will also sit inside your whole mix much more easily. There are times when you need to apply different amounts of compression to specific frequency bands such as when compressing drums. In these cases you can isolate say the kick drum and the snare, providing a boost to the kick, while suppressing the snare. This multi band compressor allows you to define 4 bands, with separate threshold, ratio, gain, attack and release times for each. We also provide an automatic gain mode, often referred to as make-up which automatically boosts the signal as you decrease the threshold. Once the compressor gate is triggered simply adjust the gain to suite. This effect effectively splits the frequency domain into 4 bands using 3 crossover controls. We provide gate and peak lights for all four compression bands as well as allowing you to mute specific bands which might be useful if you are wanting to remove a frequency range from the mix. This is one of a suite of AUv3 compatible plugins which will also soon be available from 4Pockets.

Based on creative techniques developed by studio engineers and producers in the early 1980s, Shimmer Delay Ambient Machine combines reverb, pitch shifting, and feedback to create out-of- this-world soundscapes and spaces. Great for guitars, keys, synths, samples, and vocals, Shimmer Delay Ambient Machine promotes getting lost in creative production and electronic music facets of the ambient spectrum. Swell crescendo means to start at a low volume and then swell to a much louder level, which is similar the sound of a violin being bowed. Now you get those sweeping swells from your guitar using the auto swell section of the Shimmer Delay Ambient Machine. The Shimmer Delay Ambient Machine user interface is designed with an emphasis on user control and playability. Shimmer Delay Ambient Machine has been designed to be tweaked in real time. All of the sliders have a smoothed response, to avoid clicks when changing settings or automating the controls. At the same time, the algorithm has been highly optimized, so you get a huge delay sound without straining your CPU. Works as a standalone app, AudioUnit v3 effect, or Inter-App Audio effect
