VoiceCleaner 1.1.5

VoiceCleaner 1.1.5 by Steamburger Studios

What's new in 1.1.5

• Quieter, even pauses. A new Pause clean-up stage (Advanced → Noise reduction) turns
  down the background left between phrases and after the last word to an even, quiet room
  tone, never to digital silence. Speech is not touched, and a laugh or breath in a pause stays
  as it is. The AI model keeps its gate open for a moment after speech, so the end of a take
  used to be much noisier than its start: on a real 6-second take, the trailing pause was
  31 dB below the speech and the lead-in 41 dB. With 1.1.5 both are 55-56 dB below, and
  hiss above 8 kHz in the pauses is 15-23 dB lower. It follows the Noise Reduction slider
  (and Smart settings), like the other noise controls.
• Noise learned from short pauses. A third of a second of steady noise before the first
  word is now enough to learn the background automatically (it was a second). When there is
  no learned profile, about 0.4 s of steady noise across all the pauses is now trusted for the
  profile noise reduction (it was 0.75 s). Short, changing stretches (a rustle, a door) are
  still not used.
• Batch and the command line learn the noise before the first word too, as the Enhance
  tab does when a recording opens, so a file comes out the same either way. Batch Preview
  uses it as well.
• EQ warning. When the EQ cuts the body of the voice (250 Hz-1 kHz) by 9 dB or more,
  a note under the EQ says it can sound hollow or distant. The EQ is still applied as set.

Speech cleanup and enhancement for WAV recordings: noise and room reduction, neural voice
re-synthesis, EQ and tonal balancing, dynamic leveling, loudness, recording (microphone and
desktop audio), sessions and playback. Works offline.

Which download?

	Download	Size
Most PCs (standard, CPU)	VoiceCleaner-1.1.5-win64.msi (installer)	290 MB
	VoiceCleaner-1.1.5-win64-portable.zip (no install)	353 MB
NVIDIA graphics card (faster)	VoiceCleaner-GPU-1.1.5-web.exe: small installer that downloads the rest	1 MB (downloads 2.25 GB)
	VoiceCleaner-GPU-1.1.5-win64-portable.zip.001 + .002 (no install)	3.00 GB

• Voice re-synthesis model: the 490 MB model is downloaded once, from NVIDIA's
  official repository, the first time you use Voice Re-synthesis. Everything else works
  offline.
• Standard vs GPU: both editions install to the same place, and installing one
  replaces the other.
• GPU portable ZIP: open the .001 file with 7-Zip. Or join
  the parts in a command prompt with `copy /b VoiceCleaner-GPU-1.1.5-win64-portable.zip.001
  • VoiceCleaner-GPU-1.1.5-win64-portable.zip.002 VoiceCleaner-GPU.zip`, then unzip.
• GPU installer without the web installer: download the VoiceCleaner-GPU-1.1.5-win64.msi
  and every vcgpu*.cab file into one folder, then run the .msi.
• Unsigned builds: Windows SmartScreen may warn on first run. Choose More info →
  Run anyway. Verify downloads with SHA256SUMS.txt.
• FFmpeg: VoiceCleaner ships an LGPL build of FFmpeg to open M4A, AAC, WMA and video files.
  Its source code is attached (ffmpeg-source-*.tar.gz).

Requirements: Windows 10/11 64-bit, 8 GB RAM. GPU edition: NVIDIA driver 570 or newer.

macOS (arm64)

	Download	Size
Mac (Apple Silicon, M1 or later)	VoiceCleaner-1.1.5-macos-arm64.dmg: open it and drag VoiceCleaner to Applications	197 MB
	VoiceCleaner-1.1.5-macos-arm64.zip: the same app, zipped	197 MB
	SHA256SUMS-macos.txt: checksums to verify the downloads

Requires macOS 12 or newer. Noise reduction runs on the CPU and Voice Re-synthesis on the
Apple GPU (Apple Silicon). The 490 MB voice re-synthesis model downloads the first time that
feature is used; everything else works offline.

First launch: this build is not notarized by Apple, so macOS blocks it the first time.

1. Open VoiceCleaner from Applications. When macOS says it cannot verify it, click Done.
2. Open System Settings > Privacy & Security, scroll down and click Open Anyway
   next to the VoiceCleaner message, then confirm with your password.

You only need to do this once. (On macOS 14 and earlier you can also right-click
VoiceCleaner and choose Open; macOS 15 Sequoia removed that shortcut.)

Desktop audio: System audio (all apps) records what the Mac plays (macOS 14.2 or newer;
macOS asks once for System Audio Recording permission). On older macOS, install a loopback
driver such as BlackHole; it is then listed under Desktop audio. Microphone recording works
on every version; macOS asks for permission the first time.

Opens more than WAV: M4A voice memos, AAC, MP3, FLAC, Opus/OGG, AIFF, WMA, AMR and the
sound of videos (MP4, MOV, MKV, WebM, AVI). Formats beyond WAV/FLAC/MP3/OGG/AIFF are decoded by
an LGPL build of FFmpeg inside the app, compiled from the source attached to this release.

~/Library/Logs/VoiceCleaner, sessions in ~/Documents/VoiceCleaner Sessions.
