SelfCorder

The android application was made primarily because I couldn't find any application which allowed me to record myself singing along to a song. Thus, SelfCorder was born.
It allows you to choose an audio file, and record a video while the audio is simultaneously playing. You can record yourself in a quiet environment using earphones. The high-quality recording can be used as an audition tape of yourself. On speakers, the audio will interfere, so unless that is what you want, I recommend earphones.

The application has been programmed using Apache Cordova, so if anyone wants to port the app to iOS or other mobile platforms, it should be straightforward to do so. You're welcome to get your hands dirty.
