A plug-in to work with the Auto-Tune technology and provide real-time pitch correction and auto-tune vocal effects, including format correction, natural and artificial vibrato controls, or throat modeling technology. Along with that, it features the humanize control, low latency, and MIDI capabilities.
Auto-Tune (or autotune) is an audio processor introduced in 1996 by American company Antares Audio Technologies. Auto-Tune uses a proprietary device to measure and alter pitch in vocal and instrumental music recording and performances.
YouTuber Conor Maynard, who has received criticism for his use of Auto-Tune, defended the audio processor in an interview on the Zach Sang Show in 2019, stating: "It doesn't mean you can't sing ... auto-tune can't make anyone who can't sing sound like they can sing ... it just tightens it up ever so slightly because we're human and we are not perfect, whereas [Auto-Tune] is literally digitally perfect".
Its pitch correction module is efficient and easy to use, earning Graillon 2 the number one spot on the autotune freebie list. It is compatible with all digital audio workstations on Windows and macOS.
This free autotune effect is flexible and easy to operate, with adjustable speed, range, scale, and depth. The added stereo widening feature can be helpful in a vocal processing chain, but make sure to double-check your mix in mono when using it.
Aside from those few drawbacks, MAutoPitch is a brilliant free autotune VST that could quickly become your go-to pitch correction tool. Just like Graillon 2, it is compatible with all VST and AU plugin hosts on PC and Mac.
GSnap is an old freeware autotune plugin. It was the first free autotune VST on the market. Pitch correction software was still somewhat of a rarity back in the day when GSnap was released.
Unlike Graillon 2 and MAutoPitch, GSnap will only work on Windows-based systems. It does come with a very well-written manual, though. The instructions are worth reading if you decide to use GSnap as your go-to free autotune effect.
Although Voloco is available as a VST3 and AU plugin on desktop operating systems, it is primarily used on iOS and Android. The app version of Voloco is easily the best free autotune for mobile devices.
However, you can still use autotune (not to be confused with the Auto-Tune brand) in Audacity by downloading a free plug-in called GSnap. GSnap allows you to autotune and adjust the pitch of your recorded files on Windows, Mac, and Linux computers.
12. From now on, when you view the "Effect" tab on Audacity, GSnap will be listed as one of the available effects. When clicked, it will open a window that lets you autotune your audio file.
The GSnap window itself has over a dozen knobs and options, each of which can be used to autotune the selected audio. Experiment with the options, or check out GSnap's online manual for more information.
Schematics of some of the implemented components to achieve FIB-SEM automation and its results. (a) Automated Coincidence Point routine is illustrated schematically. When not tuned, the two beams are usually pointing at different positions of the sample surface (green plane, blue point for FIB center, red point for SEM center). The orange plane below shows the case where the ideal position (yellow point) is achieved for both FIB and SEM beams. In the software routine, a square is sputtered with the ion beam on the sample surface. The offset between the two beams is calculated based on the difference between the center of the sputtered mark in the SEM and FIB images (dy, distance between red and blue positions in the green plane). The z height (dz) of the stage is then corrected, and a further refinement using the SEM beam shift is performed by calculating the translation of the square mark between FIB (50 pA image) and SEM images. (b) Milling & Trench Detection: (1) After finding the coincidence point, a trench is milled to expose a cross-section at the region of interest. (2) The trench is detected to accurately position the field of view. First, three-level thresholding is applied to the image, followed by the detection of the biggest connected component that fits a trapezoid shape. From the final binary shape, boundaries of the trapezoid are found (3): the top corners (red circles), the trapezoid top center (blue circle), and the trapezoid center (light blue circle). (c) Image features detection: The image of the cross-section surface is analyzed and scored for the best focus positions to perform autofocus and autostigmatism. Features inside the image are found by using Harris corner detection and the variance of a small region surrounding each detected corner position. The initial features (red points) highlight the high contrast and complex areas of the imaging surface which usually cluster on cellular structures. Features are clustered and their centroids (green dots) are then filtered and prioritized to detect the first 6 ones suitable for AFAS (blue points). Due to the brightness/contrast settings to make the cell visible well inside the cross-section, the top surface of the sample above the cellular edge, which is covered with a gold coat, is only faintly visible. This region is excluded from the analysis of the cross-section to prevent autofocus outside the proper field of view. (d) Acquired data: Images are acquired at 200 nm intervals (in z) throughout the Golgi apparatus region. The resulting stack is used for 3D render and quantifications. (e) Multi-site images: Result of an experiment, where multiple targets had been acquired automatically across the full surface of the sample. Scale bars: (a) all 50 µm; (b) all 25 µm; (c) 5 µm; (d) slices all 2 µm, model 5 µm; (e) 500, 50 µm. 2b1af7f3a8
