用LabVIEW实现分析输入音频的谐波成分

G.723的文档和实现-G.723 file and impliment

Opus is a totally open, royalty-free, highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet, but is also intended for storage and streaming applications. It is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype"s SILK codec and Xiph.Org"s CELT codec.

音频文件格式，包括WAV、ADPCM、CDR，另外还有AU文件格式，后面的音频数据即可以是一般的数据，也支持按CCITT G.721 (32 kbit/s) 和 G.723 (24/40 kbit/s)格式压缩好的音频数据-audio file formats, including WAV, ADPCM, CDR, another AU document format, as the audio data that may be general information, and support by CCITT G.721 (32 kbit/s) and G.723 (nometastases kbit/s) good audio compression format data

提取音乐（wav格式）中两种和弦特征：chromagram和tonalcentroid。其中chromagram是12维特征，根据十二平均律而来；tonalcentroid是在十二平均律的基础上加入了和弦结构信息（五度循环圈）得到的六维信息。-Extraction of music (wav format) in the characteristics of the two chords: chromagram and tonalcentroid. Chromagram which is 12-dimensional features, according to十二平均律come tonalcentroid is the basis of十二平均律joined the chord structure of information (five degrees circle) received the six-dimensional information.

在噪声环境下语音信号的增强，效果不错的，而且比较简单，易于理解-in the noise environment to enhance the voice signal, the effect good, but relatively simple, and easy to understand

音乐，电子音乐合成。12分律 1.在钢琴演奏中G音的和弦我们常用G7和弦.不用G和弦.为什么?  2.在乐理中G7和弦5724组成音中2音省略只用574为什么?(和声学中五级七和弦省去第五音) 在12平均律中音的频率 G4=392.00Hz B4=493.89Hz D4=293.66Hz F4=349.23Hz  在纯律中音的频率 G4=396.00Hz B4=495.00Hz D4=293.33Hz F4=352.00Hz  在纯律中D音二个的频率.一个由G和弦产生297.00Hz另一个由Dm和弦产生293.33Hz  G4=396 D=396x3/2/2=297 (钢琴无这个频率)  A4=440 Dx3/2=440 D=293.33 (5度相生律.12平均律.纯律皆D=293)  当前G和弦 D4音=293.33Hz故不会合谐.当D4音=297Hz 才会合谐所以G和弦不会合谐  G7和弦才会合谐.因此有经验的作曲家在配合弦时常用G7和弦而不用G和弦.

这个 c + + 程序是在附录中以下章节中详细描述的浊音的语音分离算法的软件实现。这种算法是其 2004 IEEE 货运上神经网络文章简化及略有改进的版本。我们已在这里源代码。在 Microsoft visual c + + 6.0 开发了这个程序。 "HuWang.exe" 文件生成具有以下设置：

这是一个能够查看wav数据的软件，简单易用！容易操作。-This is a wav be able to view data software, easy to use! Easy to operate.

播放.WAV文件，并显示其波形-players. WAV files, and display its waveform

wave文件播放类(可循环播放)-wave player category (players can be recycled)
