我有一阵列,包含一个MP3流。
如果我想要能够转换成一个WAV,那么是否应当假设这一流必须进一步编码?
在其目前的 by状态中,是否能够发挥基本功能,如获得/设立职位(假日)?

Yeah, MP3文档与WAV文档有很大不同。 西维协会的档案中含有从开始至尾以样品形式显示的原始视听数据,同样,比图文件也含有从左到右上、上到底的粉子的原始数据。 你们可以认为,作为声音波段的比图画——但不是像彩色,而是在两个频道上播音灯,通常每秒4 100次,如果它带有定型,每频道2次。
(鉴于你能够实际计算西维协会档案的卷宗量——储存1分钟的录音,你需要60秒钟,* 44100个样本 * 2个频道* 2个按字节=10.09MB)。)
MP3文件载有经数学修改的这种形象,并丢弃人可以听到的录音。 它同样致力于打压图像。
象录像卡最终需要比照图才能工作一样,声音卡最终需要WAV数据,以便与你合作。
在Mp3案卷一开始,数据集称为ID3 标签,其中载有关于档案的基本资料——艺术家姓名、跟踪长度、名称等。 您可使用改为/write ID3 tags in C#。
至于声音本身,我并不肯定在C#中完全写有Mp3 decoers。 从技术上讲,没有理由不做(它也应该是良好的业绩明智的),但标准相当松散,数学紧张,因此人们往往只使用FFMpeg等物品去编码。 http://www.google.com/search?hl=en&source=hp&q=c%23+ffmpeg&btnG=谷歌+Search&aq=f&aqi=&aql=&oq=&gs_rfai= rel=“noreferer” 页: 1
如果你不需要做任何特殊处理,而你只是想做录音,那么你可以使用WPF/Silverlight

将MP3改为WAV,使用类似于以下的代码:
Stream inputStream = ...;
Stream outputStream = ...;
using (WaveStream waveStream = WaveFormatConversionStream.CreatePcmStream(new Mp3FileReader(inputStream)))
using (WaveFileWriter waveFileWriter = new WaveFileWriter(outputStream, waveStream.WaveFormat))
{
byte[] bytes = new byte[waveStream.Length];
waveStream.Read(bytes, 0, waveStream.Length);
waveFileWriter.WriteData(bytes, 0, bytes.Length);
waveFileWriter.Flush();
}
根据“Rei Miyasaka”的答复,在C#. 公开来源中也写了MP3 decoder。 查阅Mp3Sharp。
