Post-production that polishes every word

Editing, mastering, noise removal, and format optimization. Deliver broadcast-ready audio — whether AI-generated or human-recorded.

Editing

Cut, rearrange, and refine at the script level. Silence trimming, pacing adjustment, and section re-generation without re-recording the whole piece. For dubbed content, multi-track alignment keeps translated audio synced to the original video. Batch editing handles high-volume projects where individual review would be impractical.

Mastering

Loudness normalization is the invisible skill of professional audio. Every distribution platform has a target — YouTube expects -14 LUFS, Spotify -14 LUFS, Apple Podcasts -16 LUFS, broadcast TV -24 LUFS. Deliver audio that doesn't get auto-adjusted (and quality-flattened) by the platform's own algorithm.

EQ and compression tune vocals for clarity across playback devices — earbuds, car speakers, laptop stereo, home theater. Mastering presets are one click; custom mastering is available for enterprise clients.

Noise removal

AI-powered noise removal handles background hum, air conditioning, room echo, sibilance, and mouth clicks. Works on both AI-generated audio and uploaded human recordings. Especially useful for reclaiming legacy human recordings for repurposing.

Format optimization

  • Output formats: MP3, WAV, OGG, FLAC, AAC
  • Sample rates: 8kHz (IVR/telco), 16kHz (voice), 44.1kHz (music/streaming), 48kHz (video/broadcast)
  • Bitrates: 64kbps (voice, storage-optimized) to 320kbps (high fidelity)
  • Batch export: Same audio in multiple formats and sample rates simultaneously

We produce a daily 45-minute finance podcast. Manual mastering was taking us two engineer-hours per episode. With aivoices.in's post-production API in our pipeline, mastering is done by the time our editor uploads. It saved us the cost of a full-time audio engineer.
