如何使用NAudio将音频文件转换为320kbps的.M4A？

Question

When I try to convert audio file to .m4a with this code

using (var reader = new MediaFoundationReader(input))
    //encoder.Encode(output, reader);
    MediaFoundationEncoder.EncodeToAac(reader, output, 320000);

It always returns a file with bitrate of 192/195kbs. Even this code

var bit = MediaFoundationEncoder.GetEncodeBitrates(AudioSubtypes.MFAudioFormat_AAC, 44100, 2);

returns bitrates up to 192000.

How do I encode it to 320000kbps instead?

Answer 1

With MediaFoundationEncoder you can only encode at the bitrates that media foundation offers. You'll need to find an alternative encoding tool for other bitrates
