.wav到.flac的c#转换器

本文关键字：转换器 flac wav | 更新日期: 2023-09-27 18:05:35

我的程序正在录制。wav格式的声音，并将其转换为。flac格式
我将把这个。flac文件发给google，希望我能得到声音的文本。
但是当我的程序试图将文件发送到谷歌时出现错误，"该进程无法访问文件'C:'Users'Ahmad Mustofa'Documents'Visual Studio 2010'Projects'FP'voice。因为它正在被另一个进程使用。"。我不知道哪个进程还在使用那个文件。下面是我的代码:

        string inputFile = Path.Combine("wav ", input);//the converter
        string outputFile = Path.Combine("flac", Path.ChangeExtension(input, ".flac"));
        if (!File.Exists(inputFile))
            throw new ApplicationException("Input file " + inputFile + " cannot be found!");
        WavReader wav = new WavReader(inputFile);
        FlacWriter flac = new FlacWriter(File.Create(outputFile), wav.BitDepth, wav.Channels, wav.SampleRate);
        // Buffer for 1 second's worth of audio data
        byte[] buffer = new byte[wav.Bitrate / 8];
        int bytesRead;
        do
        {
            bytesRead = wav.InputStream.Read(buffer, 0, buffer.Length);
            flac.Convert(buffer, 0, bytesRead);
        } while (bytesRead > 0);
        flac.Dispose();
        flac = null;
        wav.Dispose();
        wav = null;
        //the sender
            FileStream FS_Audiofile = new FileStream("C:''Users''Ahmad Mustofa''Documents''Visual Studio 2010''Projects''FP''voice.flac", FileMode.Open, FileAccess.Read);
            BinaryReader BR_Audiofile = new BinaryReader(FS_Audiofile);
            byte[] BA_AudioFile = BR_Audiofile.ReadBytes((Int32)FS_Audiofile.Length);
            FS_Audiofile.Close();
            BR_Audiofile.Close();
            HttpWebRequest _HWR_SpeechToText = null;
            _HWR_SpeechToText = (HttpWebRequest)WebRequest.Create("http://www.google.com/speech-api/v1/recognize?xjerr=1&client=chromium&lang=de-DE&maxresults=1&pfilter=0");
            _HWR_SpeechToText.Method = "POST";
            _HWR_SpeechToText.ContentType = "audio/x-flac; rate=44100";
            _HWR_SpeechToText.ContentLength = BA_AudioFile.Length;
            _HWR_SpeechToText.GetRequestStream().Write(BA_AudioFile, 0, BA_AudioFile.Length);
            HttpWebResponse HWR_Response = (HttpWebResponse)_HWR_SpeechToText.GetResponse();
            if (HWR_Response.StatusCode == HttpStatusCode.OK)
            {
                StreamReader SR_Response = new StreamReader(HWR_Response.GetResponseStream());
            }

.wav到.flac的c#转换器

您确定FlacWriter会自动处理Stream吗?您可以尝试这样做:

...
using (var flacStream = File.Create(outputFile))
{
    FlacWriter flac = new FlacWriter(flacStream, wav.BitDepth, wav.Channels, wav.SampleRate);
    // Buffer for 1 second's worth of audio data
    byte[] buffer = new byte[wav.Bitrate / 8];
    int bytesRead;
    do
    {
        bytesRead = wav.InputStream.Read(buffer, 0, buffer.Length);
        flac.Convert(buffer, 0, bytesRead);
    } while (bytesRead > 0);
    flac.Dispose();
    flac = null;
}
