kandi X-RAY | stk Summary

stk is a C++ library typically used in Audio, Audio Utils applications. stk has no bugs, it has no vulnerabilities and it has medium support. However stk has a Non-SPDX License. You can download it from GitHub.

The Synthesis ToolKit in C++ (STK) is a set of open source audio signal processing and algorithmic synthesis classes written in the C++ programming language. STK was designed to facilitate rapid development of music synthesis and audio processing software, with an emphasis on cross-platform functionality, realtime control, ease of use, and educational example code. The Synthesis ToolKit is extremely portable (most classes are platform-independent C++ code), and it's completely user-extensible (all source included, no unusual libraries, and no hidden drivers). We like to think that this increases the chances that our programs will still work in another 5-10 years. STK currently runs with "realtime" support (audio and MIDI) on Linux, Macintosh OS X, and Windows computer platforms. Generic, non-realtime support has been tested under NeXTStep, Sun, and other platforms and should work with any standard C++ compiler. The only classes of the Synthesis ToolKit that are platform-dependent concern sockets, threads, mutexes, and real-time audio and MIDI input and output. The interface for MIDI input and the simple Tcl/Tk graphical user interfaces (GUIs) provided is the same, so it's easy to experiment in real time using either the GUIs or MIDI. The Synthesis ToolKit can generate simultaneous SND (AU), WAV, AIFF, and MAT-file output soundfile formats (as well as realtime sound output), so you can view your results using one of a large variety of sound/signal analysis tools already available (e.g. Snd, Cool Edit, Matlab). The Synthesis Toolkit is not one particular program. Rather, it is a set of C++ classes that you can use to create your own programs. A few example applications are provided to demonstrate some of the ways to use the classes. If you have specific needs, you will probably have to either modify the example programs or write a new program altogether. Further, the example programs don't have a fancy GUI wrapper. If you feel the need to have a "drag and drop" graphical patching GUI, you probably don't want to use the ToolKit. Spending hundreds of hours making platform-dependent graphics code would go against one of the fundamental design goals of the ToolKit - platform independence. For those instances where a simple GUI with sliders and buttons is helpful, we use Tcl/Tk (which is freely distributed for all the supported ToolKit platforms. A number of Tcl/Tk GUI scripts are distributed with the ToolKit release. For control, the Synthesis Toolkit uses raw MIDI (on supported platforms), and SKINI (Synthesis ToolKit Instrument Network Interface, a MIDI-like text message synthesis control format).

            Load STK applet on SIM card boot
            Asked 2021-Jun-12 at 13:50

            Are there any methods that a Sim Toolkit applet is selected when phone boots or SIM card is inserted on phone?

            I want an applet on a SIM card that automatically executes some commands and display a message when SIM is installed on phone or phone boots.

            STK Applet got 3 methods 'process','processToolkit'and 'install'. I don't know if each of methods 'process','processToolkit' can be called during phone boot or SIM installation on phone?



            Answered 2021-Jun-12 at 13:50

            This is possible. You have to register the event EVENT_PROFILE_DOWNLOAD during the applet installation.



            How can I pass all the variables as a list and download multiple csv with few lines of code instead of several lines?
            Asked 2021-Jun-11 at 04:15

            I have around 50 stocks for which I need to pass the variable ticker1, ticker2, ticker3.....ticker50 in the URL. Currently, I wrote a repetitive 50 URLs where I pass Tickers from ticker1, ticker2...ticker50 seperately. How can I acheieve it without repeating the lines of code?

            So intead of having url1...url2....url50, I have one single url where it loops in all the tickers for ticker1-50 and it retrieves/downloads multiple csv in a given path.

            Below is my repetitive code which achieves the result but i want to optimize it and make it clutter free.

            Home screen showing null future builder in firebaseAuth Flutter
            Asked 2021-Jun-10 at 16:48

            I am currently trying to get the current user state from FirebaseAuth and switch between home screen if user didn't logged out or splash screen if user is logged out. User registration and login are both successful and registered in firestore database. But everytime i closes the application from my phone and re opens, the MediaQuery.of(context) width has a null value and shows an error.

            But the bottom navigation bar is still showing. It works when i rebuild the app and login again, it brings me to the home screen. It only occurs when i close and re open the app.

            I guess the culprit is this line:

            How can I detect when an order fills using the Interactive Brokers Java API?
            Asked 2021-Jun-04 at 15:45

            The IBKR TWS (Trader Workstation) is a tool for managing stock orders in the stock market, by Interactive Brokers. They provide an API to automate orders, like placing orders, cancelling orders, and more.

            I'm creating a program to handle executed orders in my Trader Workstation using the Interactive Brokers Java API.

            I'm having trouble detecting when an order fills.

            The documentation describes that the execDetails callback (which is an EWrapper method, see code below) is invoked when an order is filled, but I tried using that and the execDetails callback was never invoked (I tested this by logging the reqid int in that callback, and I never got any log).

            I have also researched about the completedOrder callback, which I'm not sure if that's the callback that will be invoked when an order is filled, because I tested both callbacks with a simple log, and nothing was outputting in the console.

            I don't understand the reqExecutions function and whether I need that. I have already read the documentation on this callback, and I don't understand what I'm doing wrong. I want to know I how can detect when an order fills, or executes in the TWS using their API.


            Here is my current code:



            Answered 2021-Jun-04 at 15:45

            Here is code that works, I tested with api 9.81.

            Note that if you're using clientID 0 then you should also get callbacks from trades place in TWS. I've never tried, but the docs are clear.

            It looks like you're largely asking about style. I'm going to take your code and edit it to be more in keeping with what I would do, then I'll comment below.



            Flutter App Issue with Json Decode - Data from Socket
            Asked 2021-May-23 at 09:54

            A Short explanation about my App. I get data from a socket server which is written in python, the data are in Json Format. When the data arrive i use Json Decode to convert it to a List. This list i use for a Listview builder to display the data. So far so good, but my problem is, that sometimes i get an Exception ([ERROR:flutter/lib/ui/] Unhandled Exception: FormatException: Unexpected character) I dont understand why sometimes everthing works perfect and sometimes i get this Error. If i use a real device this error comes more often

            First, you need to call persist only at entities that are created with new. But this will not give you speed performance.

            The flush slows the application down every time you use it, because here the query will be send to the database. To speed up your application you have to minimize the use of flush. In your case, just do one flush after you updated your entites.

            Add new column "code" to each dataframe and concatenate them. Obviously, rows for Z198, sup and S222, stk will be missing. The solution is to .reindex the final dataframe with product of code and mode values. The function .reindex will add NaNs to missing rows automatically.
