No. We only offer full bandwidth wav files. MP3 is a ‘compressed’ sound file format, so the quality is not as good. There are dozens of variations available when converting to MP3. Each variation will give you different sound quality and different sound file sizes. It’s best to start with uncompressed, high quality sound files. That way if want a different variation, you can always return to the original files and re-convert. This allows you to experiment, making your own decision of file size vs. sound quality. The higher the quality, the bigger the file size. Mp3 converter apps are readily available, you can even use iTunes.
