Java: way to completely disable any Swing unwanted beeps?

阅读更多关于 Java: way to completely disable any Swing unwanted beeps?

问题 I am working on a fairly complex Java application using Swing. On some occasions there are unwanted beeps without any user intervention. No crash, application keeps working fine, I'm respecting the EDT rules etc. Yet in some cases a beep can be heard: I may be doing something silly triggering that beep but in any case it s not a user action for it can happen upon importing data, when the user is away. Is it possible, for a Java application that should never ever emit any sound to configure it

Is it possible to generate complex tones in C#?

阅读更多关于 Is it possible to generate complex tones in C#?

问题 I need to create a sound containing tones of many different frequencies. Is there any way to do this in C#? The only tone generating methods I've seen so far involve console.beep, which works, but only for pure tones (single frequencies). 回答1: The Audiere library makes this extremely easy to do. Here's a nearly complete C# program to generate the DTMF tone for the "1" button: AudioDevice device = new AudioDevice(); OutputStream tone1a = device.CreateTone(697); // part A of DTMF for "1" button

问题 referencing to Hoans answer here Jelly Bean Beep In Speech Recognition I tried to implement a speech recognizer in the background. And it works all fine. The service runs in background and listens to words the user say. My problem is: If a music player is running and the speech recognizer restarts, the system sound stream is muted to prevent the beep sound of speech recognition. But muting this stream paues and mutes the music player, too. Does anyone have an idea how to prevent the beep

问题 I have a device that a user interacts with alongside of a C# WPF program. This program must beep when the user presses a button on the device, for either a specified amount of time or for as long as the user presses the button, whichever is shorter. The only speaker available to produce the beep/tone is the computer BIOS speaker; we cannot assume that other speakers are around (and it's actually safe to assume that there won't be any other speakers). How can I produce a continuous tone for

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Microsoft Windows Logo（下文简称MSWLogo）的发声依靠SOUND命令实现（类似于C语言里的beep函数），如果要实现拼接成一段旋律，有时还需要用到WAIT命令实现休止符的效果。 1、SOUND命令，播放声音，后接参数为包含两个参数的LIST，第一个参数为频率，第二个参数为发声时长 2、WAIT命令，等待指定长度的时间，后接参数为1/60秒的倍数一台88键的钢琴，每个键都有自己固定的频率，计算此频率的公式可以参考维基百科条目：钢琴键的频率： https://en.wikipedia.org/wiki/Piano_key_frequencies （目前这一条目并还没有被收入汉语维基，所以感兴趣的朋友只能看英文版）要实现弹琴的效果，可参照如下步骤：第一步，建立两个全局变量，SOUND_LENGTH是每个音节的默认长度，WAIT_LENGTH是每个休止符的默认长度 MAKE "SOUND_LENGTH 200 MAKE "WAIT_LENGTH 50 第二步，创建两个Procedure，用于播放单个音符 TO PLAY_SOUND :NOTE LOCALMAKE "FREQ GET_FREQ :NOTE LOCALMAKE "SOUND_PAIR [] LOCALMAKE
