To get started using AudioMass just head to the site and click “use a sample” to start exploring the audio editing tools. You can record directly into AudioMass by clicking the red record button at the top of the interface. You can import existing MP3s that you own into AudioMass to edit the audio playback.
There are about a dozen and a half effects that you can edit in AudioMass. Some of those include fade in/ fade out, distortion adjustments, reverb adjustments, and playback speed.
When you are satisfied with your audio file in AudioMass you can export as an MP3 file.
Applications for Education
AudioMass could be a good option for an audio editing tool that you can use on your Chromebook or for an alternative to desktop programs like Garage Band and Audacity.
