Dolby On: Record Audio & Music

Dolby On, developed by Dolby Laboratories Inc., transforms mobile devices into portable recording tools by embedding digital signal processing (DSP) chains directly into the capture pipeline. Rather than acting as a standard voice recorder, Dolby On applies automated signal processing upon audio or video capture, mitigating room acoustic flaws, ambient mechanical noise, and microphone limitations.

The application's underlying processing engine executes a multi-stage audio enhancement pipeline. Upon capturing or importing an audio stream, Dolby On performs dynamic noise reduction to attenuate low-frequency HVAC hums or electrical hiss, followed by de-essing to smooth sibilant vocal frequencies. Next, dynamic equalization curves and spatial audio widening are applied to project a broad stereo soundstage. Finally, multi-band compression and peak limiting boost signal fullness and prevent clipping distortion, bringing master loudness levels in line with modern commercial streaming standards.

Dolby On functions as both a standalone audio recorder and a video recording platform, processing video audio tracks through the identical signal processing pipeline. The software includes six customizable sound style presets (such as Amped, Natural, Deep, or Thump) that function as sonic filters. Additionally, users can adjust bass, midrange, and treble parameters manually, crop start and end points, or import external audio files from other production tools. Recorded files can be exported as uncompressed WAV audio or high-bitrate video containers directly to external Digital Audio Workstations (DAWs) like Ableton Live, Logic Pro, or BandLab.
