Play Audio File using Free C# API

NAudio allows .NET programmers to play audio files from their own .NET applications. In order to play an audio file, first, you need to open the file using AudioFileHeaer. After your file is successfully opened you can use WaveOutEvent as an output device to play audio. You can simply play audio by passing AudioFile to outPutDevice with Init method and call Play() method.

Free C# API to Convert MP3 to WAV file

The API allows the developers to convert MP3 files to other file formats. The developers can add an MP4 conversion feature in their own application if the ACM MP3 codec is present in the application machine. This codec is usually pre-installed in most versions of Windows. Converting MP3 to WAV is pretty simple you just need to open an MP3 file using MP4FileReader and convert it using WaveFileWriter.CreateWaveFile() method.

Concatinate Multiple Audio Files via C#

The API allows the developers to concatenate multiple audio files into a single audio file. The concatenation process is pretty simple. You can load your multiple audio files using AudioFileReader() method and concatinate them using ConcatenatingSampleProvider() method.
