Buanzo LAME External Encoder for Audacity

Curated MP3 presets, safe command previews, and optional automatic setup for Audacity's external-program export path.

What this is

Buanzo LAME External Encoder for Audacity is an independent 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.

Current release: version 0.2.3 for 64-bit Windows. It keeps the optional Audacity setup inside the directly launched GUI process and makes the MSI wait for that foreground flow instead of finishing while its confirmation dialog is still opening. It also includes the console-free export launcher, verified-export result panel with output-folder and copy-path actions, the executable-path quoting repair for installs under C:\Program Files, stable LAME 3.100, experimental LAME 3.101, package manifests, upstream provenance, and SHA-256 checksums.

Unsigned Windows package: Windows or Microsoft Edge may warn that this new installer is not commonly downloaded. That is expected for this unsigned release, but do not bypass an actual malware detection. Download only from this page and compare the exact SHA-256 shown above.

Experimental release: This wrapper and its optional Audacity auto-configuration are still under active testing. When the project reaches beta, this page will publish VirusTotal report links for each distributed installer and executable. Until then, use the SHA-256 checksums and package provenance supplied with the download.

What the MSI configures

The final setup page includes a checked option named Configure Audacity for the current Windows user. If selected, setup adds one interactive wrapper command to Audacity's external-program history and selects it inside that exporter. It does not replace Audacity, change the normal MP3 exporter, or change the general default export format.

  1. Close Audacity before finishing setup. If it is open, the configurator asks you to close it and retry.
  2. Leave the checkbox selected for automatic setup, or clear it if you want to configure Audacity manually.
  3. In Audacity, open Export Audio and choose (external program). The Buanzo wrapper command will already be selected.
  4. If setup was skipped, use Configure Audacity Integration from the Windows Start menu later.

The configurator creates a backup, avoids duplicate commands, and removes only its own integration during a normal interactive uninstall. Version 0.2.3 keeps the actual Audacity 3.7.5 configuration regression coverage, repairs the broken command written by version 0.2.0, launches configuration without opening Windows Terminal, and keeps the MSI open until the optional foreground configuration action finishes.

After encoding

A successful interactive export shows a dedicated MP3 created successfully panel with the verified output path and file size. Use Open containing folder to select the MP3 in Windows Explorer, or Copy output path to copy its full location.

Verify the download in PowerShell

Get-FileHash "$env:USERPROFILE\Downloads\buanzo-audacity-lame-ui-0.2.3-windows-x64.msi" -Algorithm SHA256

Compare the result to the MSI SHA-256 listed above. If it differs, delete the file.

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 Legacy mono ABR voice preset targeting 56 kbps; short or simple audio can encode lower. --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.
