Make Background Music Automatically Duck Under Voiceovers with Audacity Auto-Duck & AI BGM
Stop keyframing volume envelopes by hand. Use free open-source Audacity Auto Duck (or sidechain compression) so background music smoothly dips whenever you speak and swells during pauses.
CORE TOOLS
Audacity (Open-Source Audio Editor), Suno / Royalty-Free Music
BEST FOR
Podcasters, video essayists, audiobook creators, audio editors
REQUIREMENTS
Free open-source Audacity; voice track and instrumental BGM
✦ WHY THIS WORKFLOW
Static music volume is either too loud during speech or too quiet during pauses. Auto-ducking dynamically carves space for your voice while keeping musical energy alive.
I am producing a [tech explainer video / late-night podcast] and need instrumental BGM plus Audacity Auto-Duck settings.
Provide:
1) 3 English Suno `Instrumental` prompts designed as "bed music" (sparse midrange so it never clashes with voiceovers);
2) Exact recommended values for all 5 Audacity `Auto Duck` parameters (Duck amount, Maximum pause, fade-down/up times).
