kandi X-RAY | q Summary

q is a C++ library typically used in Audio, Audio Utils applications. q has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Q is a cross-platform C++ library for Audio Digital Signal Processing. Aptly named after the "Q factor", a dimensionless parameter that describes the quality of a resonant circuit, the Q DSP Library is designed to be simple and elegant, as the simplicity of its name suggests, and efficient enough to run on small microcontrollers. Q leverages the power of modern C++ and efficient use of functional programming techniques, especially function composition using fine-grained and reusable function objects (both stateless and stateful), to simplify complex DSP programming tasks without sacrificing readability. Q is the host of some experimental Music related DSP facilities such as Virtual Pickups (Virtual pickup placement simulator) and Bitstream Autocorrelation (An extremely fast and efficient pitch detection scheme) the author has accumulated over the years as part of research and development, and will continue to evolve to accommodate more facilities necessary for the fulfillment of various Music related projects. The library is Open Source and released under the very liberal MIT license.

            So, this is a good opportunity to use purrr::map. You are half way there by applying code to one dataframe.

            You can take the code that you have written above and put it into a function.

            Find proportion of times each character(A,B,C,D) occurs in each column of a list which has 3 datasets
            Asked 2021-Jun-15 at 19:00

            I have a list (dput() below) that has 4 datasets.I also have a variable called 'u' with 4 characters. I have made a video here which explains what I want and a spreadsheet is here.

            The spreadsheet is not exactly how my data looks like but i am using it just as an example. My original list has 4 datasets but the spreadsheet has 3 datasets.

            Essentially i have some characters(A,B,C,D) and i want to find the proportions of times each character occurs in each column of 3 groups of datasets.(Check video, its hard to explain by typing it out)



            Answered 2021-Jun-09 at 19:00

            We can loop over the list 'l' with lapply, then get the table for each of the columns by looping over the columns with sapply after converting the column to factor with levels specified as 'u', get the proportions, transpose, convert to data.frame (as.data.frame), split by row (asplit - MARGIN = 1), then use transpose from purrr to change the structure so that each column from all the list elements will be blocked as a single unit, bind them with bind_rows

            Swing JMenuBar not rendering properly
            Asked 2021-Jun-15 at 18:31

            First time actually using anything to do with swing - sorry for the poor code and crude visuals!
            Using swing for a massively over-complicated password checker school project, and when I came to loading in a JMenuBar, it doesn't render properly the first time. Once I run through one of the options first, it reloads correctly, but the first time it comes out like this: First render attempt
            But after I run one of the methods, either by clicking one of the buttons that I added to check if it was just the JFrame that was broken or using one of the broken menu options, it reloads correctly, but has a little grey bar above where the JMenuBar actually renders: Post-method render

            The code for the visuals is as follows:

            You should separate creating your menu from your content. Please review the following example. I decoupled your menu, component, and event logic into meaningful phases.

            You need to check for "q" before you use the value. You need to convert given to float BEFORE you add it in to the sum. The statement count+1 does nothing; it computes count + 1 and throws it away. This should work.

            A "for expression" must return unit, so the result is not propagated. For example:
