如何同时播放多个mp3/wma文件？
我需要在我的 WP7 应用程序中同时播放多个音效。 我目前使用它处理大约 5 MB 的 wav 文件，而不是用 wma/mp3 编码时的 500kb。
代码的当前部分：
Stream stream = TitleContainer.OpenStream(String.Format("/location/{0}.wav", value)
SoundEffect effect = SoundEffect.FromStream(stream);
effect.Play();
这在循环中效果很好，准备所有效果，然后播放它们。
然而，我真的很想使用 mp3/wma/whatever-codec 来精简我的 xap 文件。
我尝试使用 MediaElement，但看来您也无法使用它来播放多个文件。此外，XNA MediaPlayer 无法实例化，并且据我所知，无法同时播放多个文件。
我看到的唯一解决方案是，我以某种方式将 mp3 解码为 wav 并将该 Stream 提供给 SoundEffect。
关于如何实现多重播放有什么想法吗？或者有关如何将 mp3 解码为 wav 的建议？
I have the need to play multiple soundeffects at once in my WP7 app.
I currently have it working with wav files that takes around 5 megabyte, instead of 500kb when coded in wma/mp3.
Current part of the code:
Stream stream = TitleContainer.OpenStream(String.Format("/location/{0}.wav", value)
SoundEffect effect = SoundEffect.FromStream(stream);
effect.Play();
This works great in a loop, preparing all effects, and then playing them.
However, I would really like to use mp3/wma/whatever-codec to slim my xap file down.
I tried to use MediaElement, but it appears that you also can't use that to play multiple files. Also the XNA MediaPlayer can't be instantiated, and as far as I experienced can't be made to play multiple files at once.
The only solution I see left is that I somehow decode the mp3 to wav and feed that Stream to SoundEffect.
Any ideas on how to accomplish the multiple playback? Or suggestions on how to decode mp3 to wav?

关于转换...抱歉 - 但我认为目前没有任何 api 可用于 WMA 或 MP3 解码。
另外，我认为没有任何 MP3、WMA 或 Ogg 解码器的实现可以在纯 c# 代码中使用 - 我见过的所有解码器都使用 DirectShow 或 PInvoke - 例如，请参阅 C# 音频库。
我个人确实希望音频/视频压缩/解压缩在不久的将来在 WP7 API 中可用 - 但我无法猜测什么时候！
对于一些简单的压缩，您可以尝试诸如发送单声道而不是立体声文件，或者发送 8 位而不是 16 位音频文件 - 这些很容易在手机上转换回 16 位（分辨率明显下降）。
使用像 zip 这样的压缩也可能有助于某些声音效果......但我不认为它会取得巨大成功。
On the conversion... sorry - but I don't think there's any api currently available for WMA or MP3 decoding.
Also, I don't think there are any implementations of MP3, WMA or Ogg decoders which are available in pure c# code - all of them I've seen use DirectShow or PInvoke - e.g. see C# Audio Library.
I personally do expect audio/video compression/decompression to be available at some point in the near future in the WP7 APIs - but I can't guess when!
For some simple compression you can try things like shipping mono instead of stereo files, or shipping 8 bit rather than 16 bit audio files - these are easy to convert back to 16 bit (with obvious loss of resolution) on the phone.
Using compression like zip might also help for some sound effects... but I wouldn't expect it to be hugely successful.
