DeYin

DeYin helps you truly understand a musical recording more quickly.
Record vocals or instruments – or import an existing recording. DeYin analyzes the melody and turns sound into a visible and editable musical structure: pitches, pitch movements, and playing techniques are displayed on a timeline.
You can listen to the original recording while observing what is happening in the music. Automatic analysis results can be compared directly with what you hear and corrected manually.
Listen → analyze → see → correct → understand.
This combination of analysis and your own corrections makes DeYin a tool for learning. Instead of simply receiving a finished result, you engage directly with the sound and develop a more precise understanding of the music.
DeYin also provides time-synchronized lyrics and export to Sanpu, MIDI, SRT, and video with a transparent background.
The original recording, analysis results, and your own corrections can be saved and edited again later.
DeYin is designed for musicians, learners, and anyone who wants not only to hear or play music, but to understand it more deeply.
DeYin does not generate music and is not a replacement for a Digital Audio Workstation (DAW). Automatic analysis results are intended as an aid and may vary depending on the recording and musical material.
All audio data and analysis are processed locally on the device.
