Hello, I'm trying to play an audio (I'm coding in C# SDK)

I converted .mp3 to raw by audio conversion software, and when i play the .raw on audacity is sounds pretty fine

I tried to use _ezb.SoundV4.PlayData function like this:

byte[] bytes = File.ReadAllBytes("../path");

_ezb.SoundV4.PlayData(bytes,100);

but the audio sounds really bad

when i try to play the .mp3 in ARC it sounds better.

any ideas? thank you!

Must save PCM as MONO 8 BIT and 14700 hz

I recommend loading and playing the file in real-time like this... Here's how the soundboard loads and plays the file. I compress the file so it can be stored in a much smaller memory footprint


if (openFileDialog1.FileName.ToLower().Contains(".mp3")) {

  using (NAudio.Wave.Mp3FileReader mp3 = new NAudio.Wave.Mp3FileReader(openFileDialog1.FileName)) {

    using (NAudio.Wave.WaveFormatConversionStream pcm = new NAudio.Wave.WaveFormatConversionStream(new NAudio.Wave.WaveFormat(EZ_B.EZBv4Sound.AUDIO_SAMPLE_BITRATE, 8, 1), mp3)) {

      using (MemoryStream ms = new MemoryStream()) {

        using (GZipStream gz = new GZipStream(ms, CompressionMode.Compress))
          pcm.CopyTo(gz);

        _compressedAudioArray = ms.ToArray();
      }
    }
  }
} else if (openFileDialog1.FileName.ToLower().Contains(".wav")) {

  using (NAudio.Wave.WaveStream wav = new NAudio.Wave.WaveFileReader(openFileDialog1.FileName)) {

    using (NAudio.Wave.WaveFormatConversionStream pcm = new NAudio.Wave.WaveFormatConversionStream(new NAudio.Wave.WaveFormat(EZ_B.EZBv4Sound.AUDIO_SAMPLE_BITRATE, 8, 1), wav)) {

      using (MemoryStream ms = new MemoryStream()) {

        using (GZipStream gz = new GZipStream(ms, CompressionMode.Compress))
          pcm.CopyTo(gz);

        _compressedAudioArray = ms.ToArray();
      }
    }
  }
} else {

  throw new Exception("Unsupported audio file type.");
}

Playback like this...


using (MemoryStream ms = new MemoryStream(_compressedAudioArray))
using (GZipStream gz = new GZipStream(ms, CompressionMode.Decompress))
  EZBManager.EZBs[_cf.SoundBoardv4.EZBIndex].SoundV4.PlayData(gz, 100);
