Convert SHN audio files to WAV or MP3, with mkwACT
You will seldom find shn audio files, but if you do and you need to convert them to MP3, most converters will prove unable.
You can convert shn files easily with the MKW Audio Compression Tool, a free program that will turn your shn files to the wav format. Shn is in fact a wav variation, with a ‘light’ compression.
I have not found a tool that would convert immediately shn to mp3, but perhaps you wouldn’t want to miss the special features (vbr conversion, etc) of your favorite mp3 converter.
Therefore, convert first to wav, and then use a good mp3 converter, such as XRecode or the Efficient WMA to MP3 Converter, to turn the wav files to mp3.
