AUDIO RESTORATION SERVICES AND SOUND PRESERVATION

Bringing voice and harmony back to memory.

Digital audio restoration for historical recordings and archival sound materials

Our service focuses on the recovery, cleaning and enhancement of already digitized sound materials, including historical recordings, film soundtracks, oral histories, interviews and music archives. We intervene on both analogue-derived transfers and native digital files affected by technical degradation.

We address a wide range of audio defects, including:

• Background noise: broadband hiss, tape noise, electrical hum, buzz and environmental interference.
• Impulsive noise: clicks, crackle, pops and transient artifacts through advanced de-clicking and spectral repair processes.
• Signal degradation: clipping distortion, dynamic compression artifacts, frequency imbalance, phase issues and stereo image instability.

Through a hybrid workflow that combines AI-assisted spectral restoration tools with precise manual editing and critical listening, we restore clarity and intelligibility while preserving the original acoustic character and documentary integrity of the source material.

This service is designed for audio archives, museums, cultural institutions, broadcasters, foundations and rights holders seeking professional sound restoration aligned with archival preservation and professional distribution standards.
