Audio Converter & Enhancer
Convert and enhance audio — voice clarity, bass/treble, volume, speed, pitch, loudness and ID3 tags — in your browser.
About the Audio Converter & Enhancer
Drop one file or a whole batch and convert them to MP3, M4A/AAC, OGG Vorbis, WAV or FLAC with ffmpeg.wasm running locally. Choose the bitrate, sample rate and channel layout, optionally normalise loudness to broadcast level, then preview each result and download it. Video files work too — the audio track is extracted automatically.
