@audio/denoise vs Aulio Studio

@audio/denoise is a free web tool for cleaning recordings and listening to or saving the result. It handles targets including steady background noise, mains hum, clicks, pops, vinyl crackle, clipping, wind rumble, plosives, sibilance, room reverb, and noise between phrases. The page describes thirteen open-source restoration methods and a classifier. Automatic mode measures properties of a recording, selects a specialized method, and displays its plan; users can instead choose methods such as dehum, declick, declip, and gate. Audio is processed in the browser, and the page says it is not uploaded or sent off the device. The approach uses classical signal processing rather than AI noise removal. For music, the page identifies hum, clicks, crackle, and clipping as treatable, while advising light use of broadband denoising and comparison with the original. Machine-learning models may perform better on heavy speech-over-noise. The associated npm package processes mono Float32Array audio. Automatic mode does not choose dereverb, which must be selected explicitly.

Aulio Studio is a paid Mac app for cleaning audio and video recordings. It removes background noise, filler words, stutters, long silences, and room echo. Live A/B preview and an adjustable noise-reduction control let you compare and set processing before applying it. The app transcribes audio, allowing selected transcript text to export its matching clip, and the maker says transcription and filler removal support 99 languages. Effects include reverb, echo, warmth, loudness targets, and sound style profiles. It processes MP4 and MOV video and exports MP3, WAV, FLAC, M4A, and AIFF. Batch jobs can share settings and remain in history. Processing runs on the Mac, while anonymous diagnostics and analytics may be sent to the maker and Google Firebase. macOS 14 or later is required. Pricing starts at $9.99 a month, with a full-access 10-day trial and no free plan.
