Blue Mangoo Parametric Equalizer is an audio unit plugin, with six bands of filter controls: - Low cut and high cut with adjustable Q (resonance) - Two bell filters with adjustable Q - Low and high shelf filters This plugin exists because we needed an equalizer that is easy to use in the small screen space of an iOS Audio Unit plugin, but still powerful enough to do relatively complex filtering. * Blue Mangoo Parametric Equalizer is an AU3 plugin. It runs within an audio unit host app such as Garage Band. It does not run as a standalone app.

De-Esser is an AUv3 Compatible plugin for your favourite DAW such as Cubasis, Auria, AUM, Meteor, BM3 (does not work as a standalone app). This is actually a trio of effects all rolled into a single package which are ideally suited but not limited to voice recordings (De-Esser, a Vocal Doubler and a Noise Gate). This De-Esser is a great tool for removing sibilance from your vocals. Sibilance is the harsh over emphasising of phonetics such as 'ss', 'sh', 'ch', 'th' etc. which tend to be made worse during the recording process. This plugin has two modes of operation, 'standard' and 'multi-band' which can be used to effectively remove this kind of problem. The standard mode emulates the ducking of a volume control just like mixing engineers used to do in the good old days, but in this case uses a compressor driven by a filtered band of the input signal that contains the problematic frequencies. This is a common and effective method which has been tried and tested for many years. The multi-band mode uses a similar filtering mechanism to isolate the effected frequency band and applies a compressor to just that range in isolation. This method gives much more pleasing and natural results as it retains the overall volume level and only effects the specified frequency range. We also included a Vocal Doubler which simulates a multi-track vocal recording. It uses sophisticated techniques that eliminates the phase cancellation issues associated with layering vocals in this way. You have complete control over delay time, levels and stereo field placement. Finally this package incorporates a Noise Gate, to remove unwanted background noise from your recording. Fully configurable threshold, attack, release and dB reduction settings are available. A visual frequency display helps you quickly find and isolate the effected frequency ranges which can also be turned off to reduce CPU load. 4 different visual modes are available to help visualise issues. A siblance filter preview button lets you listen to the problematic frequencies in isolation and a limiter is available to make headroom for the vocal doubler. This is a great addition to our AUv3 plugin range which is heavily biassed towards recording of vocals.
