bx_meter will show you Peak and RMS values of your mixes, including the relation between the two using centered, DYNAMIC LEDs. bx_meter has a Mid / Side mode (Sum and Difference) in addition to the standard L/R mode, and it offers 3 different weightings to be used to display dynamics more like you hear them. Just like many other Brainworx tools, you will find several solo switches and valuable extra features like the floating dynamic LED mode.
bx_meter does not automatically make your mixes sound better, it simply lets you look at how you are mixing or mastering with unprecedented precision. This visual information about your mix allows you to better understand the correlation of dynamics, M/S, phase and levels of what you are hearing. In return, it helps you mix and master far more accurately.
In this free video tutorial, Pro Tools Expert Team Member Julian Rodgers looks at the bx_meter plugin from Plugin Alliance, a comprehensive metering plugin offering Peak, RMS, Balance, Correlation and most interestingly dynamic range metering (DR).
The Portable Brix Meter BX-1 is a convenient refractometer that enables you to determine the Brix of food, beverage and other samples virtually anywhere!
Measurement is fast, requiring only 2 seconds.
It has a wide measurement range of 0-85% (0.2%), ample for the vast majority of samples/applications.
So, now I have inexplicable urges to get more Zeiss stuff (Zeiss acquisition syndrome). I already have a very nice Super Ikonta BX with a meter that's even accurate, and it has a coated Tessar in Synchro-Compur shutter - all the good stuff. The lens is amazingly sharp, even wide open. Now I'm thinking about the III.
Looking at online auctions, it seems that the IV gets all the attention. I'm not sure why, as it has the EV shutter/aperture system, and the selenium meter. The III is basically the IV without the two features that are most likely to be annoying: i.e. the EVS interlock, and meter.
I'm not sure why people like the IV's, other than they're newer and should be in better condition. The meter is not something I would necessarily trust, and the coupled aperture/shutter speeds are a PITA to use.
Thanks for trying to help. The BX does get 12 frames per roll, so there's not much difference there. The only thing that I can see is that the III is lighter, and lacks a light meter. The III is more streamlined looking, but the BX has that certain industrially serious look about it.
I own and use both a BX (latest version) and a III. Basically I would say this: the BX feels like a much better piece of fine engineering, and it is a pleasure even simply to handle. However I do 99% of my photography outdoor and in most cases associated with hiking/trekking/mountaineering, and the III sees at least trice the use as the BX simply because it is way more practical to carry along (it will fit nicely into the pocket of a wind jacket). Even when a Lunasix Pro meter is added in the other pocket, the combination is less cumbersome than the BX. However if it was not for these considerations, I would always pick up the BX.
The option to view the mid and side signals separately is an example of the precision visual feedback that bx_meter provides. You also have Solo listen buttons for the left, right, mid, and side signals.
I like plugins that help you understand a problem properly before fixing it. The visual feedback you get from bx_meter tells you what you are hearing and why, so you can make the best possible decisions for your mix/master.
To get the most out of the meter, add this meter into more than one of your audio effects plug-in slots after everything else on your master bus channel.
This way you will benefit from selecting different displays in each meter eg: stereo in one meter / mid side in another meter & so on.
Then you can monitor all of your meters at once if you need to have them all open at once (i think it has 4 different displays to choose from in the meter).
I do it like this because you can solo each meter to actually hear that process too ?
Mastering requires a balanced, highly tuned processing chain, which can be both complex and expensive. The bx_masterdesk plug-in takes much of the guesswork out of the mastering process by combining several parameters into single controls with carefully chosen individual audio processors, each pre-tuned for easy and effective results.
The Texmate BX-B31 is a modular compact bargraph meter which features a 31 segment Red (standard), Green (optional) or Amber (optional) display in horizontal or vertical formats. The BX-B31 is housed in a 1/16-DIN (96 X 24 mm) case which easily mounts in both thick and thin panels (up to 2")
The BX-B31 is part of the Lynx family of meters which features more than 33 different inputs via Texmate's I-Series plug-in signal conditioning modules, including AC/DC Current, AC/DC Voltage, Process, Resistance, Strain-Gage, Temperature and many more! The BX-B31 is available with either AC or DC power and can be configured with optional set-point relay outputs.
The main out has a switch to set output levels to -4dBm or -10dBm (corresponding to 0 on the output meter) and the RCA output is -10dBm. I guess that helps with running the mixer in the reds. Just in case anyone missed that.
As specific gravity was the basis for the Balling, Brix and Plato tables, dissolved sugar content was originally estimated by measurement of specific gravity using a hydrometer or pycnometer. In modern times, hydrometers are still widely used, but where greater accuracy is required, an electronic oscillating U-tube meter may be employed. Whichever means is used, the analyst enters the tables with specific gravity and takes out (using interpolation if necessary) the sugar content in percent by mass.
It is not, typically, actually necessary to consult tables as the tabulated Bx or P value can be printed directly on the hydrometer scale next to the tabulated value of specific gravity or stored in the memory of the electronic U-tube meter or calculated from polynomial fits to the tabulated data, in fact, the ICUMSA tables are calculated from a best-fit polynomial.
Dissolution of sucrose and other sugars in water changes not only its specific gravity but its optical properties, in particular its refractive index and the extent to which it rotates the plane of linearly polarized light. The refractive index, nD, for sucrose solutions of various percentage by mass has been measured and tables of nD vs. Bx published. As with the hydrometer, it is possible to use these tables to calibrate a refractometer so that it reads directly in Bx. Calibration is usually based on the ICUMSA tables,[6] but the user of an electronic refractometer should verify this.
where n D \displaystyle n_D is the refractive index measured at the wavelength of the sodium D line (589.3 nm) at 20 C. Temperature is very important as refractive index changes dramatically with temperature. Many refractometers have built in "Automatic Temperature Compensation" (ATC) which is based on knowledge of the way the refractive index of sucrose changes. For example, the refractive index of a sucrose solution of strength less than 10 Bx is such that a 1 C change in temperature would cause the Brix reading to shift by about 0.06 Bx. Beer, conversely, exhibits a change with temperature about three times this much. It is important, therefore, that users of refractometers either make sure the sample and prism of the instrument are both at very close to 20 C or, if that is difficult to ensure, readings should be taken at 2 temperatures separated by a few degrees, the change per degree noted and the final recorded value referenced to 20 C using the Bx vs. Temp slope information.
As solutes other than sucrose may affect the refractive index and the specific gravity differently, this refractive "Brix" value is not interchangeable with the traditional hydrometer Brix unless corrections are applied. The formal term for such a refractive value is "Refractometric Dry Substance" (RDS). See Brix and actual dissolved solids content below.
Modern optical Brix meters are divided into two categories. In the first are the Abbe-based instruments in which a drop of the sample solution is placed on a prism; the result is observed through an eyepiece. The critical angle (the angle beyond which light is totally reflected back into the sample) is a function of the refractive index and the operator detects this critical angle by noting where a dark-bright boundary falls on an engraved scale. The scale can be calibrated in Brix or refractive index. Often the prism mount contains a thermometer which can be used to correct to 20 C in situations where measurement cannot be made at exactly that temperature. These instruments are available in bench and handheld versions.
Digital refractometers also find the critical angle, but the light path is entirely internal to the prism. A drop of sample is placed on its surface, so the critical light beam never penetrates the sample. This makes it easier to read turbid samples. The light/dark boundary, whose position is proportional to the critical angle, is sensed by a CCD array. These meters are also available in bench top (laboratory) and portable (pocket) versions. This ability to easily measure Brix in the field makes it possible to determine ideal harvesting times of fruit and vegetables so that products arrive at the consumers in a perfect state or are ideal for subsequent processing steps such as vinification.
Due to higher accuracy and the ability to couple it with other measuring techniques (%CO2 and %alcohol), most soft drink companies and breweries use an oscillating U-tube density meter. Refractometers are still commonly used for fruit juice.
When a sugar solution is measured by refractometer or density meter, the Bx or P value obtained by entry into the appropriate table only represents the amount of dry solids dissolved in the sample if the dry solids are exclusively sucrose. This is seldom the case. Grape juice (must), for example, contains little sucrose but does contain glucose, fructose, acids, and other substances. In such cases, the Bx value clearly cannot be equated with the sucrose content, but it may represent a good approximation to the total sugar content. For example, an 11.0% by mass D-Glucose ("grape sugar") solution measured 10.9 Bx using a hand held instrument.[citation needed] For these reasons, the sugar content of a solution obtained by use of refractometry with the ICUMSA table is often reported as "Refractometric Dry Substance" (RDS)[8] which could be thought of as an equivalent sucrose content. Where it is desirable to know the actual dry solids content, empirical correction formulas can be developed based on calibrations with solutions similar to those being tested. For example, in sugar refining, dissolved solids can be accurately estimated from refractive index measurement corrected by an optical rotation (polarization) measurement.[9]
