如何更改.wav格式文件比特率 [英] How to change .wav format file bit-rate

问题描述

大家好，



在我的应用程序中我有一些.wav格式的音频文件，所以在这里我想改变比特率，因为我使用下面的代码

Hi all,

In my application i ahve some .wav format audio files,so here i want to change Bit rate, for that i am using below code

int bitrate;
           using (var reader = new WaveFileReader(textBox1.Text))
                      {
                          bitrate = reader.WaveFormat.AverageBytesPerSecond * 8;
                          reader.Dispose();
                      }
          if (bitrate > 128000)
           {
               using (var reader = new WaveFileReader(textBox1.Text))
               {
                   var newFormat = new WaveFormat(8000, 16, 1);
                   using (var conversionStream = new WaveFormatConversionStream(newFormat, reader))
                   {
                       WaveFileWriter.CreateWaveFile(@"C:\Docs\Files\", conversionStream);
                   }
               }
           }

它仅适用于某些文件，有些文件可用低于错误

it is working for some files only, and some files get below error

An unhandled exception of type 'NAudio.MmException' occurred in NAudio.dll

Additional information: AcmNotPossible calling acmStreamOpen

如何解决错误？

- 我在使用Naudio Dll



我尝试了什么：

How can i solve the error ?
--Here i am using Naudio Dll

What I have tried:

int bitrate;
            using (var reader = new WaveFileReader(textBox1.Text))
                       {
                           bitrate = reader.WaveFormat.AverageBytesPerSecond * 8;
                           reader.Dispose();
                       }
          if (bitrate > 128000)
            {
                using (var reader = new WaveFileReader(textBox1.Text))
                {
                    var newFormat = new WaveFormat(8000, 16, 1);
                    using (var conversionStream = new WaveFormatConversionStream(newFormat, reader))
                    {
                        WaveFileWriter.CreateWaveFile(@"C:\Docs\Files\", conversionStream);
                    }
                }
            }
