Frequently Asked Questions

How does auto-ducking work?

The Automixer detects speech in your voice track and automatically lowers the music volume during speech, then smoothly fades it back up during pauses.

What audio formats can I import?

You can import MP3, WAV, OGG, FLAC and most other common audio formats. The output is rendered as high-quality audio.

Can I use ENDE's music library directly?

Yes! When opened from a song page, the music track is automatically pre-loaded into the Automixer so you can start mixing right away.

Is the audio processed on a server?

No. All mixing, ducking, noise reduction and export happens entirely in your browser using the Web Audio API. Nothing is uploaded.

Production

100% handmade

A human composed, played and arranged this track. No AI wrote a single note here.

Depending on the piece that means 40 to 100 hours: the idea, the melody, the chords, recording takes and throwing them away again, arrangement, mix. The slow way.

And it still costs you nothing. No subscription, no watermark, commercial use included. If you would like to give something back, donate to a charity. You do not owe me anything.
Staying honest: The mastering runs through LANDR — and LANDR is an AI. Composition, performance and arrangement are 100% human; that final polishing step is not.

Production

AI-assisted

The melody and the idea are mine. The AI worked them out.

I write the musical DNA — chord progression, structure, melody — on the keyboard in Cubase or FL Studio, often including a recorded audio sample. The AI takes over the part I never loved: laying brick upon brick. I am the architect, the AI is the construction crew.

Why at all? 778 tracks here were made entirely by hand — that took me years. The library now holds 2,392 pieces, all free, all from one person. A large catalogue, completely free and everything fully handmade: those three do not add up together.

And the result costs you nothing. No subscription, no watermark, commercial use included — exactly as with the handmade tracks. If you would like to give something back, donate to a charity.
