Loudness Normalizer queue and input/output measurements during batch processing
Standalone Mac application

A complete, focused workflow without a DAW, plug-in host or cloud processing service.

Fast batch processing

Prepare a single recording or move an entire queue through the same repeatable process.

Local AI noise reduction

Speech Focus AI helps reduce background noise while production audio stays on the Mac.

DELIVERY WITH CONFIDENCE

Every file measured.
Every result verified.

Loudness Normalizer analyzes the source, applies precise correction, exports the selected format and measures the finished file again. Input and output values remain visible side by side, so the result never has to be guessed.

PRECISION PROCESSING

Know exactly what changed.

Compare the original recording with the verified export and confirm that the requested target and True Peak limit were reached.

  • Integrated loudness in LUFS
  • True Peak level in dBTP
  • Loudness Range in LU
  • Applied gain and final difference

PROFESSIONAL PRESETS

Start with the destination.

Ready-to-use targets cover common broadcast, podcast, voiceover and online delivery workflows. Custom settings remain available when a client or broadcaster specifies something different.

  • EBU R128 Europe · −23 LUFS
  • ATSC A/85 US · −24 LUFS
  • Podcast stereo and mono targets
  • YouTube, streaming, audiobook and voiceover presets
Processing Preview with Original and Processed A/B modes, stereo waveform, section selector and gain matching

GAIN-MATCHED A/B PREVIEW

Hear the processing before export.

Choose any section of the selected file and switch instantly between Original and Processed playback. Loudness matching keeps the comparison honest, while the stereo waveform and moving playhead make the audition easy to follow.

  • Original and Processed switching during playback
  • Automatic 20-second preview preparation
  • Gain-matched comparison calculated from PCM audio
  • Resizable stereo waveform with movable position

BATCH WORKFLOW

From a full queue to delivery-ready files.

Add the recordings once, choose the destination and let every file move through the same repeatable process.

Add

Drop individual files or complete folders into the processing queue.

Configure

Select the loudness target, True Peak limit and required output format.

Process

Analyze, correct, encode and verify every recording automatically.

Review

Compare final measurements and reveal the completed output files.

INTELLIGENT CLEANUP

Prepare speech before normalization.

Speech Focus AI uses artificial intelligence to reduce distracting background noise and improve spoken-word clarity before loudness correction. The AI runs locally on the Mac—production audio does not need to leave the standalone application.

BETA Always review critical broadcast material before delivery.

Current processing controls with loudness target, dynamics profile, Speech Focus AI, Adaptive Leveler, High Pass Filter and Noise Reduction levels

COMPLETE OUTPUT CONTROL

Built for the file the project actually needs.

Flexible formats

Preserve the source format or export WAV, AIFF, MP3 or FLAC with project-specific settings.

Professional resolution

Choose 16-bit or 24-bit PCM, sample rates up to 192 kHz and MP3 bitrates up to 320 kbps.

Organized delivery

Select an output folder, add automatic filename suffixes and optionally create a mono mixdown.

Source protected

Every result is written as a new file. Original recordings remain untouched.

Private by design

Analysis, AI enhancement and loudness processing all run locally on the Mac.
