Export & Rendering¶

17 tools for audio export, rendering, format conversion, and audio file management.

Export & Rendering (13)¶

Tool	Description
`auto_gain`	Auto-adjust output volume to hit a target LUFS
`convert_audio`	Convert an exported WAV to MP3 or FLAC using ffmpeg
`export_midi`	Export a note region's notes as a standard MIDI file (.mid)
`export_mix`	Render the full project mix to a WAV file
`export_single_stem`	Export a single AU as a stem WAV with its effect chain applied
`export_dry_stem`	Export a single AU as a DRY stem (instrument output, no effects)
`export_stems`	Export each AU as a separate stem WAV file
`export_stems_format`	Export stems and convert each to MP3 or FLAC
`import_midi`	Import a MIDI file and create note events on a note track
`load_audio`	Load an audio file (WAV/MP3/FLAC/OGG) into the project
`measure_lufs`	Measure LUFS (integrated) and true peak of an exported WAV
`render_full`	Render the entire project as a single stereo WAV
`render_full_format`	Render and convert to MP3 or FLAC in one step
`render_range`	Render only a portion of the project for quick A/B comparison

LUFS targets¶

Platform	Target LUFS
Spotify	-14
Apple Music	-16
YouTube	-14
TIDAL	-14
SoundCloud	-14
CD master	-9 to -7

Use auto_gain with a target LUFS to automatically adjust output volume:

await server.mcp_opendaw_auto_gain(target_lufs=-14)

Rendering workflow¶

graph LR
    A[Render call] --> B[OfflineEngineRenderer<br/>48kHz]
    B --> C[WAV file]
    C --> D{convert_audio}
    D -->|mp3| E[MP3 file]
    D -->|flac| F[FLAC file]
    D -->|none| G[WAV only]

Example: full mastering chain¶

# Add mastering effects on the output bus
await server.mcp_opendaw_add_mastering_chain(
    style="balanced"  # or: warm, loud, transparent
)

# Render full mix
await server.mcp_opendaw_render_full(output_path="mix.wav")

# Measure loudness
lufs = await server.mcp_opendaw_measure_lufs(file_path="mix.wav")
print(f"Integrated: {lufs['integrated']} LUFS, True peak: {lufs['true_peak']} dBTP")

# Auto-adjust to target
if lufs['integrated'] > -14:
    await server.mcp_opendaw_auto_gain(target_lufs=-14)
    await server.mcp_opendaw_render_full(output_path="mix_mastered.wav")

Audio Files (2)¶

Tool	Description
`get_sample_info`	Get detailed info about an audio sample by UUID
`list_samples`	List all audio file samples used in the project

Presets & DawProject (4)¶

Tool	Description
`export_dawproject`	Export the current project as .dawproject (Bitwig/Ableton compatible)
`export_preset`	Export an AU as a preset (base64-encoded binary)
`import_dawproject`	Import a .dawproject file into the current session
`import_preset`	Import a preset (base64-encoded binary) as a new audio unit
