Dual Channel FFT

Dual Channel FFT is a free metering plugin developed by Christian Budde. Compatible OS(s): Windows.

Dual Channel FFT is a program that analyses the spectral difference between two measurement points. This can be useful to measure the electro- and acoustical chain during a live performance.

Additionally the program can visualize the processing of VST Plug-ins, export the frequency response to TXT/BMP and export the impulse response to WAV.

Dual Channel FFT is free for non-commercial use.

Correlometer

Correlometer is a free correlation meter VST, VST3, Audio Unit, AAX plugin developed by Voxengo. Compatible OS(s): Windows 64b, macOS.

Correlometer is an analog-style stereo multi-band correlation meter plug-in based on the correlation meter found in the PHA-979 phase-alignment plugin.

Multi-band correlation meter is an advanced way to check for presence of out-of-phase elements in the mix. Broadband correlation metering reports overall phase issues and may misrepresent problems present in select spectral bands, while multi-band correlation meter easily highlights problems present in mid to high frequencies that are not easily heard by ear, but may still reduce clarity of the mix. Another application of multi-band correlation metering is phase- and time-aligning of channels and tracks, especially bass and bass-drum pairs, guitar mic and D.I. source pairs, two-microphone stereo recordings, etc.

Correlometer can display 4 to 64 individual spectral bands, with adjustable band quality factor that controls the degree of band’s selectivity. Averaging time of correlation estimator can be adjusted. Correlometer supports side-chain inputs for easy correlation estimation between separate audio tracks.

Correlometer features:

4 to 64 band correlation meter.

Adjustable band quality factor.

Adjustable averaging time.

Side-chain input.

Resizable user interface.

All sample rates support.

Zero processing latency.

User interface color schemes.

Retina and HighDPI support.

Brainworx bx_solo

Brainworx bx_solo is a free stereo imaging and signal monitoring VST, VST3, Audio Unit, RTAS, AAX plugin developed by Plugin Alliance. Compatible OS(s): Windows 64b, macOS.

M & S solo knobs. free! Just grab it.

bx_solo is a nice little tool that we have designed to get you started with and used to the way we approach the M/S technique – be it for recording-, mixing- or mastering purposes.

Description

L (LEFT channel), R (RIGHT channel), M (MONO sum, mid signal) & S (STEREO-Difference, side signal) – and all this phase-corrected (when needed) and mono-ed out on both speakers of your system. This is very helpful when working in M/S modes (because especially listening to only the S-signal of a stereo mix is not so easy to do with modern DAW stations) and to check your signals / mixes for errors, noises, clicks, whatever…

bx_solo also contains a stepped M/S Stereo Width Control, so you can get an impression about what you can actually do with it. Do try it out on subgroups (makes rock guitar subgroups jump out of your speakers at about 150%!), FX returns, keyboards / samplers, etc.

Using the Stereo Width Control too heavily may lead to phase problems. bx_control & bx_digital both have the Mono Maker on board – this tool will be able to get rid off these phase problems with its unique way of mono-ing out your stereo signals / mixes only in the bass frequencies – Mono Maker is the solution – unless you really over-do the settings…

To be able to fine-adjust the Stereo Width Control (and use Mono Maker at the same time for best results!) please try bx_control.

Features:

Fully automatable.

“Mouse Over” feature: adjust the parameters by holding the mouse over any knob and simply turn your mouse wheel.

Direct access: just type in any valid number into the text fields for direct access to the exact value.

Bitter

Bitter is a free bitscope VST, VST3, Audio Unit, RTAS, AAX plugin developed by schwa. Compatible OS(s): Windows 64b, macOS.

Bitter is a 64-bit bitscope and intersample clip indicator.

Bitter shows how many of the available bits are being used by the audio signal, reports clipping samples, and estimates when digital-to-analog conversion would cause inter-sample clips.

Typical uses for a bitscope include: verifying that a render dither is working properly; verifying that a particular plugin is not reducing the signal bit depth; testing for faulty audio source data.

aXMeter

aXMeter is a free metering VST3, Audio Unit, AAX plugin developed by SSA Plugins. Compatible OS(s): Windows 64b, macOS.

aXMeter is an Ambisonic meter plugin that shows you the RMS and peak levels of all the Ambisonic channels, up to seventh order. The channels for each order are grouped together for easy viewing.

By default, aXMeter shows the channel levels up to third-order. If the input signal is of higher order, the plugin window will expand to reveal the gains for the higher order channels.

The aXMeter is ideal for checking signal levels between encoding with the aXPanner and decoding with the aXMonitor.

Input: Any Ambisonics format up to seventh-order.

Note: AAX version requires Ambisonic buses present only in Pro Tools Ultimate.
