Audio Enhancer

Auphonic

Auphonic is an automated audio post-production service that applies professional mastering to podcasts, videos, and audiobooks without requiring audio engineering expertise. It combines noise and reverb reduction, an intelligent leveler that balances speakers against music, filtering and auto-EQ with de-esser and de-plosive processing, and loudness normalization to meet broadcast LUFS and true-peak specs. Beyond mastering, Auphonic can automatically remove silence, filler words, and coughs across multiple languages, produce multitrack mixdowns with ducking and noise gating, and generate speech-to-text transcripts, chapters, and show notes. It offers automated publishing to platforms like YouTube, Libsyn, and SoundCloud, plus an API, CLI tools, and Zapier integration, making it popular with podcasters, video creators, and broadcasters including BBC Radio, iHeartRadio, and MSNBC.

Voice Isolator

Voice Isolator is an AI-powered web application that removes background noise and isolates vocals from audio files. Instead of manually editing waveforms or applying traditional filters, the service uses deep-learning algorithms to identify the human voice and separate it from music, ambient sound, and other unwanted noise in one pass. Users upload an audio file, wait a few seconds for cloud processing, and download clean vocal or instrumental results for further editing or publishing. The workflow is intentionally minimal: drag and drop or browse to choose an MP3, WAV, M4A, AAC, FLAC, or OGG file, and the platform's AI processing engine handles the rest. The site reports support for high-resolution audio up to 192 kHz and says most vocal isolation tasks finish in seconds. A real-time preview lets users check the cleaned audio before exporting. Access is credit-based—each second of audio consumes one credit—and new users who sign in receive 60 free credits. Paid plans provide 500 to 6,000 credits per billing cycle. Voice Isolator is aimed at podcasters, music producers, content creators, audio engineers, broadcasters, and even karaoke operators who need fast, professional-sounding vocal separation. It positions itself as a privacy-conscious service: audio files are encrypted during transmission and processing and automatically deleted afterward. With more than 2.5 million audio files processed and over 500 million minutes of background noise removed, the tool is designed for users who want broadcast-ready audio without investing in complex desktop software.
