The await keyword is where the magic happens. In the example below, the first block is doing exactly that. It allows streaming audiotrack write async PCM audio buffers to the audio sink for playback.
Instead, it causes the compiler to sign up the rest of the async method as a continuation on the awaited task. The reason for this is outlined in the Async in Depth article. On the C side of things, the compiler transforms your code into a state machine which keeps track of things like yielding execution when an await is reached and resuming execution when a background job has finished.
Important Info and Advice Although async programming is relatively straightforward, there are some details to keep in mind which can prevent unexpected behavior. The task is a promise to produce audiotrack write async actual byte array when the task is complete.
The code expresses the intent downloading some data asynchronously without getting bogged down in interacting with Task objects.
These are blocking and return when the data has been transferred from the Java layer to the native layer and queued for playback. The introduction of blocking tasks into this can easily result in a deadlock if not written correctly.
How do you achieve this? When you await such a task, the await operation rethrows only one of the exceptions. It starts all the tasks immediately the Task. This is achieved by "pushing" the data to the AudioTrack object using one of the AudioTrack.
When the task completes, it invokes its continuation, and execution of the async method resumes where it left off. ConfigureAwait false ; After the program is done being paused, it will continue potentially on an entirely different thread with a different context. There are a lot more details to consider beyond this.
WhenAny which allow you to write asynchronous code which performs a non-blocking wait on multiple background jobs. The size of this buffer, specified during the construction, determines how long an AudioTrack can play before running out of data.
For an AudioTrack using audiotrack write async static mode, this size is the maximum size of the sound that can be played from it. For example, the task might be the result of a call to Task. This is the convention used in. Async and LINQ are powerful, but should be used together as carefully and clearly as possible.
Note that this would also be incredibly inefficient, as the state machine generated by the C compiler for the async method would not be accomplishing anything. The best way to handle this is to start a background thread which does the work using Task.
Bonus it works really well with dependency injection. Delay simulates doing work for 1 second. The async keyword turns a method into an async method, which allows you to use the await keyword in its body. Here are two questions you should ask before you write any code: Additionally, you should always measure the execution of your code.
Race conditions can typically be avoided altogether. For an introduction to async programming, see Asynchronous Programming with async and await.
Use a parsing library instead. The task to which the await operator is applied typically is returned by a call to a method that implements the Task-Based Asynchronous Pattern. WhenAll Waiting for all tasks to complete await Task. Run, and await its result. The UI thread is free to perform other work.
This example shows how you might grab User data for a set of userIds. An await expression can occur only in the body of its enclosing method, lambda expression, or anonymous method, which must be marked with an async modifier.
Example The following example returns the total number of characters in the pages whose URLs are passed to it as command line arguments.
For example, you may find yourself in a situation where your CPU-bound work is not costly enough compared with the overhead of context switches when multithreading.You should add "Async" as the suffix of every async method name you write.
This is the convention used mint-body.com to more-easily differentiate synchronous and asynchronous methods. Note that certain methods which aren’t explicitly called by your code (such as event handlers or web controller methods) don’t necessarily apply.
Apart from that answer i also used mint-body.comsync() method to play audio async. I think need not create an async mint-body.com is what playing audio asynchronously.
The stream writer is currently in use by a previous write operation. Examples The following example shows how to write a string to a. Async functions mean we can now write code which looks synchronous.
This means our code can be easier to read and reason about. Node and browser support is good and there are tools available to help support older browsers. From my understanding one of the main things that async and await do is to make code easy to write and read - but is using them equal to spawning background threads to perform long duration logic?.
The methods of mint-body.comrack are listed below. For a list of all members, see the AudioTrack list. See Also: Object. Public Methods. AttachAuxEffect: TrackStatus Attaches an auxiliary effect to the audio track. Flush() Flushes the audio data currently queued for playback.
