Import Audio Skill

You move audio files to the correct location in the user's audio directory.

Step 1: Parse Arguments

Expected format: <file-path> <album-name> [track-slug]

The track-slug is optional — only needed for stems zip imports when the track can't be inferred from the filename.

Examples:

• ~/Downloads/track.wav sample-album
• ~/Downloads/03-t-day-beach.wav sample-album
• ~/Downloads/stems.zip sample-album 01-first-taste

If arguments are missing, ask:

Usage: /import-audio <file-path> <album-name> [track-slug]

Examples:
  /import-audio ~/Downloads/track.wav sample-album
  /import-audio ~/Downloads/stems.zip sample-album 01-first-taste

Step 2: Resolve Audio Path via MCP

1. Call resolve_path("audio", album_slug) — returns the full audio directory path
2. The resolved path uses the mirrored structure: {audio_root}/artists/{artist}/albums/{genre}/{album}/

Example result: ~/bitwize-music/audio/artists/bitwize/albums/hip-hop/sample-album/

CRITICAL: Always use resolve_path — never construct paths manually.

Step 3: Detect File Type

Check the file extension and whether it's a stems zip:

File Type	Action
.wav, .mp3, .flac, .ogg, .m4a	Move to album audio dir (Step 4)
.zip (stems)	Extract to per-track stems subfolder (Step 4b)

How to identify a stems zip: The user will say "stems" or the zip contains files like 0 Lead Vocals.wav, 1 Backing Vocals.wav, etc.

Step 4: Create Directory and Move File

mkdir -p {resolved_path}
mv "{source_file}" "{resolved_path}/{filename}"

Step 4b: Import Stems Zip

Stems must go into per-track subfolders to prevent filename collisions (every track has 0 Lead Vocals.wav, etc.):

{resolved_path}/
  01-first-taste.wav
  02-sugar-high.wav
  stems/
    01-first-taste/
      0 Lead Vocals.wav
      1 Backing Vocals.wav
      2 Drums.wav
      ...
    02-sugar-high/
      0 Lead Vocals.wav
      1 Backing Vocals.wav
      ...

Workflow:

1. Determine the track slug from one of:
   • The zip filename if it matches a track pattern (e.g., 01-first-taste-stems.zip → 01-first-taste)
   • The user specifying which track (e.g., /import-audio stems.zip sample-album 01-first-taste)
   • If neither: Ask the user which track the stems belong to
2. Extract into the per-track subfolder:

   mkdir -p {resolved_path}/stems/{track-slug}
   unzip "{source_file}" -d "{resolved_path}/stems/{track-slug}"
   

3. Update track metadata: Call update_track_field(album_slug, track_slug, "stems", "Yes")

Argument format for stems: <zip-path> <album-name> [track-slug]

Step 5: Confirm

Report:

Moved: {source_file}
   To: {resolved_path}/{filename}

For stems:

Extracted stems: {source_file}
       To: {resolved_path}/stems/{track-slug}/
    Files: {count} stem files extracted
  Updated: {track-slug} stems → Yes

Error Handling

Source file doesn't exist:

Error: File not found: {source_file}

Config file missing:

Error: Config not found at ~/.bitwize-music/config.yaml
Run /configure to set up.

File already exists at destination:

Warning: File already exists at destination.
Overwrite? (The original was not moved)

MP3 Files

Suno allows downloading in both WAV and MP3 formats (WAV on Pro/Premier, web only). Always prefer WAV for mastering quality.

Downloads are metered since 2026-09-03. Free accounts get 7 lifetime trial downloads (personal use only — never releasable); Pro 20 a month; Premier 60 a month; the count resets on the billing date and does not roll over. One song is one download whatever the format, and its stems are included — download the WAV first, then pull stems later at no extra cost; re-downloading the same song is free. Premier's Suno Studio exports are uncapped and arrive as 32-bit float / 48 kHz WAV — the practical route for a full album in one month. Commercial rights attach only to a permitted download made on a paid plan.

If the user provides an MP3 file:

1. Accept the MP3 and import it normally (same path logic)
2. Warn the user:

Note: This is an MP3 file. For best mastering results, download the WAV
version from Suno instead. MP3 compression removes audio data that can't
be recovered during mastering.

If WAV isn't available, this MP3 will work but mastering quality may be limited.

3. Import the file to the same destination path as WAV files

Supported formats: WAV (preferred), MP3, FLAC, OGG, M4A

Examples

/import-audio ~/Downloads/03-t-day-beach.wav sample-album

Config has:

paths:
  audio_root: ~/bitwize-music/audio
artist:
  name: bitwize

Result:

Moved: ~/Downloads/03-t-day-beach.wav
   To: ~/bitwize-music/audio/artists/bitwize/albums/hip-hop/sample-album/03-t-day-beach.wav

Stems import example

/import-audio ~/Downloads/stems.zip sample-album 01-first-taste

Result:

Extracted stems: ~/Downloads/stems.zip
       To: ~/bitwize-music/audio/artists/bitwize/albums/hip-hop/sample-album/stems/01-first-taste/
    Files: 5 stem files extracted
  Updated: 01-first-taste stems → Yes

Common Mistakes

❌ Don't: Manually read config and construct paths

Wrong:

cat ~/.bitwize-music/config.yaml
mv file.wav ~/music-projects/audio/artists/bitwize/albums/electronic/sample-album/

Right:

# Use MCP to resolve the correct path
resolve_path("audio", album_slug) → returns full path with artist folder

Why it matters: resolve_path reads config, resolves variables, and includes the artist folder automatically. No manual config parsing or path construction needed.

❌ Don't: Mix up content_root and audio_root

Path comparison:

• Content: {content_root}/artists/{artist}/albums/{genre}/{album}/ (markdown, lyrics)
• Audio: {audio_root}/artists/{artist}/albums/{genre}/{album}/ (WAV files, stems)
• Documents: {documents_root}/artists/{artist}/albums/{genre}/{album}/ (PDFs, research)

Use resolve_path with the appropriate path_type ("content", "audio", "documents") to get the right path.
