Audio Converter is a free online audio tool from Farvixo that lets you AI-powered audio converter — batch upload, smart analysis, studio presets, noise removal & 15+ formats. Decoding and encoding both happen in your browser through WebAssembly, so recordings, interviews and voice notes never reach a server. Free and unlimited, with no watermark or audible tag added to the output. ## Specifications | Property | Value | | --- | --- | | Tool | Audio Converter — Audio Tools | | Purpose | AI-powered audio converter — batch upload, smart analysis, studio presets, noise removal & 15+ formats | | Input | One or more files (MP3, WAV, M4A, AAC, FLAC, OGG, Opus, MP3, WAV, AAC, M4A, FLAC, OGG, OPUS, WMA, AIFF, AMR, AC3) | | Output | Audio file in the selected format and bitrate | | Processing | In your browser — files are never uploaded to a server | | Price | Free, unlimited, no account required | | Limitations | Bounded by your device's memory and CPU rather than a server quota; very large files may be slow on older hardware | ## How to use Audio Converter 1. **Load your audio** — Add an audio file to Audio Converter. Processing runs locally in your browser, so your recordings are never uploaded. 2. **Choose output settings** — Pick the format, bitrate and sample rate you need, or use a preset tuned for music, podcasts or voice notes. 3. **Export the track** — Convert and download the finished file. Quality is yours to control and nothing is added to the output. ## Use cases - Fitting a podcast episode or voice note under a messaging or email size limit - Converting a recording to the format a player, DAW or upload form requires - Journalists and researchers handling interview audio that must stay private - Preparing audio for a video edit at a consistent bitrate and sample rate ## Tips - Speech is fine in mono — downmixing halves the file size with no perceptible loss on voice content. - For spoken word, 64–96 kbps is transparent; music generally needs 128 kbps or more. - Every lossy re-encode loses information. Always start from the highest-quality original you have, not from a file you already compressed. ## Common problems - **The file will not load** — The container is fine but the codec is unusual, or the file is partially downloaded. Re-download the original and try again. - **The output sounds thin or watery** — The bitrate is too low for the material. Raise it a step, and keep stereo if the source is music rather than speech. - **Volume is inconsistent across the file** — Enable loudness normalisation, which levels the track to a single EBU R128 target instead of leaving the peaks and quiet passages as they were. ## FAQ ### What audio formats are supported?
