App Description
“Freely manipulate sound with incredibly natural results.”
Make the comparison with your own ears. This music player makes it easy to independently change your music's key and playing speed and remove or extract specified sounds, while preserving an overwhelming audio quality that cannot be matched.
Recommended for:
・ Musical instrument practice.
・ Making karaoke tracks.
・ Musical transcription.
・ Creating audio tracks for dance practice.
・ Learning foreign languages by listening to podcasts.
・ Efficiently gathering information from podcasts.

With usual audio equipment, large changes to key and playing speed typically result in a heavy degradation of the audio quality. However, by using our company's “PhaseGear” technology, this app succeeds in reducing audio degradation to its utmost minimum. The result is surprisingly natural-sounding audio.
