I'm aware of the playbackRate property on the AudioBufferSourceNode, but that also changes pitch. I'm also aware of the playbackRate property for <audio> and <video> elements, but I need to use the Web Audio API. I'm very new to the Web Audio API. Is there anything I can do? 回答1: There is a way to do this - its called granular synthesis (link points to a pd theory link, but the theory is universal). The idea of

We will be marking some object from the 1st image as a reference. Using the properties of the same object in the next image, we must calculate the speed of the moving vehicle. Can anyone help me here??? I am using python opencv. I have succeeded till finding the marked pixel in the 2nd image using Optical flow method. Can anyone help me with the rest? 回答1: Knowing the acquisition frequency, you must now find the distance

Our codebase has been growing over the years and now stands at around 4 million lines of code. Compilation speed is becoming an issue. We've spent time weeding out unit circular referencing (a known cause of slow compilation) and examined every aspect of the setup. It gets to a point we can't improve it any further materially with what we can control. At the moment, on a state of the art PC with 4 cores running Windows XP SP3 and Delphi 2006, start Delphi fresh and

The reason behind an include should be that, if removed, the code doesn't compile. Don't #include when you can forward

I have a very simple object ( Item ) with a 2 ints (one is the generatedId ), a String and a double . I test the time it takes (roughly) to update the object in the database (a 100 times) with the code below. The log statement logs: time to update 1 row 100 times: 3069 Why does it take 3 seconds to update an object 100 times, in a table with only 1 row. Is this the normal ORMLite speed? If not, what might be the problem? RuntimeExceptionDao dao =

I would welcome any suggestions in the form of pseudo code... I was trying to find information on this problem, online but could not find anything. very weird since it's 2014, how could it be that there is nothing on google for this...weird! 回答1: var checkScrollSpeed = (function(settings){ settings = settings || {}; var lastPos,

Example in java code: public class Test { @IntDef({Speed.SLOW,Speed.NORMAL,Speed.FAST}) public @interface Speed { public static final int SLOW = 0; public static final int NORMAL = 1; public static final int FAST = 2; } @Speed private int speed; public void setSpeed(@Speed int speed) { this.speed = speed; } } I don't want to use enums because of their performance issues in Android.

Even pointers to open-source components are welcome. 回答1: Try using the System.Net.NetworkInformation classes. In particular, System.Net.NetworkInformation.IPv4InterfaceStatistics ought to have some information along the lines of what you're looking for. Specifically, you can check the bytesReceived property, wait a given interval, and then check the bytesReceived property again to get an idea of how many bytes/second your connection is processing. To get a good number,
