Download only audio file with fixed bitrate

[asteria121]

`
IReadOnlyList infoList;
var streamManifest = await youtube.Videos.Streams.GetManifestAsync(videoID);
var streamInfo = streamManifest
.GetAudioOnlyStreams()
.OrderByDescending(s => s.Container == Container.Mp4)
.ThenByDescending(s => s.Bitrate).FirstOrDefault();

    List<IStreamInfo> infoList2 = new List<IStreamInfo>();
    infoList2 .Add(streamInfo);
    infoList = infoList2;

    var conversion = new ConversionRequestBuilder(outputPath)
                .SetFormat("mp4")
                .SetPreset(ConversionPreset.Medium)
                .Build();

    await youtube.Videos.DownloadAsync(infoList, conversion);`

I want to stream it by NAudio. But if I download sound file like this code, bitrate is not constant (moves 100Kbps~150Kbps) and NAudio throws exception like "Mp3FileReader does not support samplerate changes". Is there any way to download only audio and fix bitrate like 192Kbps?

Are you downloading it as mp4? You can download it directly as mp3.
