Advanced LAME External Encoder UI for Audacity

Curated MP3 presets and safe LAME command previews for Audacity's external-program export path.

What this is

Buanzo Audacity LAME External Encoder UI is a Windows-first wrapper for Audacity users who want more MP3 export control than the normal Audacity MP3 dialog exposes.

Current Audacity already includes MP3 export. This tool is for advanced external-program export, where Audacity sends audio to an external command and LAME handles the final MP3 file.

Status: early preview. The wrapper source and package tooling exist, but a public Windows ZIP should only be posted here after the bundled LAME binaries are reviewed, checksummed, and verified.

Audacity command examples

Interactive preset UI:

buanzo-lame-ui.exe --ui - "%f"

Run a curated preset without opening the UI:

buanzo-lame-ui.exe --preset podcast-voice-56 - "%f"

Run the same preset with a named bundled LAME build for A/B testing:

buanzo-lame-ui.exe --preset music-vbr-standard --lame-version 3.100 - "%f"

Curated presets

Preset Use case Generated LAME options
music-vbr-standard General high-quality music MP3 exports. -V 2
podcast-voice-56 Compact mono speech and voice notes. --preset voice -a
podcast-voice-96 Clearer mono podcast or lecture speech. --preset 96 -a
compat-cbr-128 Older player compatibility and fixed bitrate publishing. --cbr -b 128
archive-cbr-192 Fixed 192 kbps deliverables. --cbr -b 192

Why use this instead of normal MP3 export?

  • Use curated LAME presets directly from Audacity's external-program export mode.
  • Preview the exact LAME command before encoding.
  • Select between bundled LAME builds, such as a stable build and an experimental build, for controlled comparison.
  • Use advanced mode for VBR, CBR, ABR, mono downmixing, and ID3 tag controls.
  • Keep community-described presets curated and safe: the wrapper validates options and does not execute shell command strings.

Not for legacy LAME library installs

If you use Audacity 2.x and need lame_enc.dll or older LAME library packages, use the wizard or legacy downloads instead.
