how to change deltarune music for covers from yt?

If you want to use Deltarune music as a base for covers or to swap it into the game, there are two different goals:

1. extracting and editing the music for covers , and
2. replacing the in‑game music files so the game plays your tracks.
   I’ll cover both, since your question mixes “for covers” and “from YT”.

Quick overview

• Deltarune’s official OSTs are available as .ogg files from the game’s folder and from the official releases on archive.org.

• YouTube doesn’t give you clean, editable audio directly; you usually download the OST or use a converter, then edit in an audio program like Audacity.

• To change the music inside Deltarune, you drop your own .ogg files into the mus folder with the same filenames as the original tracks.

1. Getting Deltarune music to make covers

Option A: Use the official OST (best quality)

This is the clean, legal way to get the music:

1. Download the OST
   • Chapter 1: https://archive.org/details/DeltaruneChapOneOST
   • Chapter 2: https://archive.org/details/kingboss_202109
     These are official releases by Toby Fox, in .ogg format.

2. Install an audio editor
   • Audacity (free): https://www.audacityteam.org/
   • Or any other editor (Reaper, FL Studio, etc.).
3. Import and edit
   • Open Audacity.
   • Drag the .ogg files into it.
   • Record your instruments/vocals on new tracks, mix, and export as MP3/WAV.

Use this method if you want high-quality audio for YouTube covers, remixes, or live performances.

Option B: Extract from YouTube (if you don’t have the OST)

If you only have YouTube links:

1. Use an audio downloader
   • Tools like yt-dlp, 4K Video Downloader, or online converters can extract audio from YouTube videos.
   • Always check copyright and terms of service; for personal practice and non-commercial covers, this is usually acceptable, but distributing high-quality rips without permission can be problematic.
2. Convert to a workable format
   • Convert the result to WAV or MP3 if needed.
   • Import into Audacity or your DAW.

This will work, but it’s lower quality than the official OST and may have compression artifacts.

2. Changing Deltarune’s in‑game music (so the game plays your covers)

If your goal is to play your own versions inside Deltarune (not just as a separate cover video), you can replace the game’s music files:

Step 1: Find the mus folder

• itch.io / Windows download version :
  Open the unzipped Deltarune folder, go into mus.
  Example path (may vary):
  Deltarune/mus.

• Steam version :
  Typical path:
  C:\Program Files (x86)\Steam\steamapps\common\DELTARUNEdemo\mus
  (adjust based on where you installed Steam).

Step 2: Prepare your audio files

• Your tracks must be in .ogg format.
• Name them exactly like the original files you want to replace (e.g., twr.ogg, field_of_hopes_and_dreams.ogg).
  You can see the original filenames in the mus folder.

• If your cover is in MP3 or WAV, convert it to .ogg using:
  • Audacity (File → Export → Export as OGG), or
  • An online OGG converter.

Step 3: Replace the files

1. In the mus folder, either:
   • Delete the original file, or
   • Rename it (e.g., twr_orig.ogg) so you can restore it later.
2. Copy your new .ogg file into the folder with the same name as the original.
3. Launch Deltarune; the game should now play your track instead of the original.

You can repeat this for any track you want to swap: field themes, boss themes, shop music, etc.

3. Making full “cover” videos (YouTube)

If your final goal is a YouTube cover video:

1. Record your cover in your DAW (FL Studio, Reaper, etc.) or use Audacity.
2. Export as MP3/WAV.
3. Get a video source:
   • Official music video from the OST channel,
   • Fan-made animation,
   • Or a simple static image with the song title.
4. Combine audio + video in:
   • OBS,
   • Shotcut,
   • Clipchamp ([https://app.clipchamp.com/).4]
5. Upload to YouTube with:
   • Clear title: “Field of Hopes and Dreams – Deltarune (Your Cover)”.
   • Credit Toby Fox as composer in the description.

Mini checklist

• Want clean audio for covers? → Use official OST .ogg files from archive.org.

• Only have YouTube? → Convert YouTube audio to MP3/WAV, then to .ogg if needed.
• Want the game to play your covers? → Put .ogg files in the mus folder with the same names as originals.

• Need to edit/mix? → Audacity is free and straightforward.
