AudioWave - Free online audio converter, editor & AI vocal extractor

Hey Product Hunt! 👋 I built Audiowave because I got tired of jumping between different audio tools every time I needed to convert a file, cut a track, or separate vocals. Most options are either expensive desktop software, sketchy online sites that upload your files to a server, or single-purpose tools that only do one thing. So I put together a complete audio toolkit that runs entirely in your browser via FFmpeg.wasm and ONNX runtime. Every conversion, edit, and AI-powered stem separation happens on your device — nothing is ever uploaded to a server. 🔥 What you can do: • Convert between 10+ audio formats (MP3, WAV, FLAC, AAC, OGG, etc.) with adjustable bitrate, sample rate, and bit depth • Edit audio — cut, trim, split, join, merge, and mix multiple tracks • Apply effects — tempo changer (50–200%), pitch shifter (±12 semitones), reverb, fade in/out, EBU R128 loudness normalizer • Separate vocals, drums, bass, and other stems with Demucs AI • Reduce background noise, hiss, and hum • Extract high-quality audio from 22 video formats (MP4, MOV, MKV, WebM, etc.) • Replace audio tracks in video files with adjustable volume mix • View detailed metadata (codec, sample rate, ID3 tags) with JSON/PDF export It's completely free, requires no sign-up, and is 100% private — your files never leave your machine. I'd love to hear your thoughts! What's missing? What would make this your go-to audio tool? 🚀
