WAV MP3 Converter converts WAV to MP3 and MP3 to WAV. It can also resample WAV and MP3 file. WAV MP3 Converter can encode MP3 or WAV with different encoding parameters (like sample frequency, bit rate and channels). This means it can convert a large-size MP3 or WAV file to a small-size one. WAV MP3 Converter supports batch conversion. You can add multiple MP3/WAV files and convert them at a time. You can also add a folder or drag and drop several MP3/WAV files and folders onto main window, and then it will search all MP3 and WAV files and add to conversion list.
