This is a AUv3 compatible analyser / tuner which can be used as plugin with your favourite DAW such as Cubasis, Meteor, Auria or GarageBand.

This plugin can be used directly within your DAW to analyse either the monitored input signal from your audio device or your mixer output. It uses Apple's accelerate framework to perform fast high resolution 8K fast fourier transformations to display a real time frequency spectrum. The result is an accurate representation of the sampled sound broken down into its frequency components.

You can use this plugin in conjunction with equalisers and parametric filters to obtain a nice flat mix or eliminate hard to find unwanted noise or hiss.

Various display modes include, linear narrow band, logarithmic narrow band, Octave, 1/3 Octave, 1/6 Octave and Mixer Mode with selectable ANSI A and C weighting curves. Up to 64 times oversampling can be applied to obtain more stable readings.

This plugin also includes a Digital Tuner mode which allows real time note detection, frequency and cents deviation from true pitch.

This is one of a suite of AUv3 compatible plugins which will also soon be available from 4Pockets.

Very responsive

This is pretty awesome, and responds very well to the input with hardly any lag. The different modes are nice for various applications. It pretty much does what you would want it to, like momentarily freezing the display, etc. My only wish is that you were able to zoom in on the frequencies to narrow the span of frequencies shown on the graph, especially in linear mode.

Very handy

Nice for checking the tuning of samples among other uses.

The tuner doesn’t works well

I´ve tried the tuner mode to get in tune my guitar but it simply is not accurate and you can’t be secure about its medition. That makes me ask you, does the LUFS meter works well? I use it in the master to know the loudness of my tracks but I really don’t know if it is accurate. Thank you for reading.

P.S: Please add a oscilloscope mode!
