在听筒模式下 am.setSpeakerphoneOn(false); setVolumeControlStream(AudioManager.STREAM_VOICE_CALL); am.setMode(AudioManager.MODE_IN_CALL); 我用Mediaplayer AudioTrack调节音量总是失败 at.setStereoVolume(vol, vol); player.setVolume(vol，vol); 后来 决定用AudioManager来调节音量 AudioManager可以修改系统Android系统的音量 下面介绍几个AudioManager的几个音量调整方面的方法. 首先是得到AudioManager实例: AudioManager am=(AudioManager)getSystemService(Context.AUDIO_SERVICE); 调整音量方法有两种,一种是渐进式,即像手动按音量键一样,一步一步增加或减少,另一种是直接设置音量值. 1、渐进式 public void adjustStreamVolume (int streamType, int direction, int flags) am.adjustStreamVolume (AudioManager.STREAM_MUSIC, AudioManager.ADJUST

I'm currently doing a very very important school project. I need to extract the information of a WAVE file in C/C++ and use the information to obtain the LPC of a voice signal. But, in order to do that, I need to do some pre-processing to the signal, like doing Zero crossing and energy analysis, among other things. Which means that I need the sign and a real value. The problem is that I don't know how to obtain useful information and the correct format for that. I have already read every single field in the file, but I'm not sure I am doing it right. Suggestions, please? This is the way I read

Well the docs finally said it, I need to take it easy on my wrist for a few months. Being that I'm a .NET Developer this could end my livelihood for a little while, something I'm not anxious to do. That said, are there any good handsfree options for developers? Anyone had success using any of the speech recognition software out there? POSTSCRIPT: I've recovered my arm again to the point where two-handed programming isn't a problem. Dragon Naturally speaking worked well enough, but was slower, not like the keyboard where I was programming faster than I thought. It's out there, and it works...

《Demons》是美国摇滚乐队Imagine Dragons（梦龙乐队）演唱的歌曲，由丹·雷诺斯、本·麦基、丹尼尔·韦恩·瑟蒙、亚历克斯·达·基德、乔希·莫瑟填词谱曲，收录在乐队首张录音室专辑《Night Visions》中，于2013年1月28日通过新视镜唱片发布。该首歌曲是电影《九层妖塔》的主题曲 。 When the days are cold 当暗无天日 And the cards all fold 当希望落空 And the saints we see 我们看见的圣人们啊 Are all made of gold 熠熠闪光，遥不可及 When your dreams all fail 当梦想沦落 And the ones we hail 当深陷逆境 Are the worst of all 这是最黑暗的日子吧 And the blood’s run stale 连血液都跟着腐朽 I want to hide the truth 我想隐藏这真相 I want to shelter you 帮你构筑虚拟的天堂 But with the beast inside 但我内心的野兽 There’s nowhere we can hide 蠢蠢欲动，呼之欲出 No matter what we breed 不管我们以何为食 We still are made of greed

I'm trying to stream audio from the mic from 1 Android to another over WiFi. After looking at some examples I made 2 applications with a single activity in each, 1 to capture and send audio and the other to receive. I've used the Audiorecord and Audiotrack classes to capture and play. However, i just hear some crackling sound (which has now stopped after i made some changes though i reverted back) The activity to send voice. public class VoiceSenderActivity extends Activity { private EditText target; private TextView streamingLabel; private Button startButton,stopButton; public byte[] buffer;

iOS devices have embedded voice synthesizers for Accessibility's VoiceOver feature. Is there a way you can use these synthesizers programmatically to generate text-based sounds? My problem is: I'm working on a simple app for kids to learn colors and rather than recording the names of the colors in each language i want to support and storing them as audio files, i'd rather generate the sounds at runtime with some text-to-speech feature. Thanks [EDIT: this question was asked pre-iOS7 so you should really consider the voted answer and ignore older ones, unless you're a software archeologist]
