Takes noisy mono or stereo audio (phone mic, untreated room, traffic), returns a podcast-ready file: denoised, dereverbed, voice warm and present. ## Try it - **Live demo:** [desert-ant-labs/clear-demo](https://huggingface.co/spaces/desert-ant-labs/clear-demo): drop in a recording and hear raw vs cleaned, fully in your browser. - **iOS / macOS:** [`clear-swift`](https://github.com/Desert-Ant-Labs/clear-swift): Swift package; both variants bundled, works offline. - **Android / JVM:** [`clear-kotlin`](https://github.com/Desert-Ant-Labs/clear-kotlin): Kotlin SDK via JitPack. - **JavaScript / TypeScript:** [`@desert-ant-labs/clear`](https://www.npmjs.com/package/@desert-ant-labs/clear): npm package for Node + browser ([source](https://github.com/Desert-Ant-Labs/clear-js)).

Works across the full range of input quality: phone audio, laptop mic, untreated rooms, USB / XLR podcast captures. | | **`clear-natural`** | Room tone, breath, lip texture preserved | Treated podcast studios, USB / XLR captures, voiceover where the original sound is intentional. | If the source is already clean and you want the model to stay invisible, pick `clear-natural`. Otherwise `clear-studio` is the default. ## Files Both variants share the same architecture and realtime cost; only the weights differ. Both variants are **6-bit palettized** (k-means LUT), ~5× smaller than the fp32 weights with no perceptible quality loss (DNSMOS OVRL within ~0.02 of the float model). | Variant | File | Format | Size | |---|---|---|---:| | `clear-studio` | `clear-studio.mlmodelc/` | Core ML, 6-bit palettized, precompiled | ~1.9 MB | | `clear-studio` | `clear-studio.onnx` | ONNX, 6-bit palettized (fp16-stored) | ~4.5 MB | | `clear-natural` | `clear-natural.mlmodelc/` | Core ML, 6-bit palettized, precompiled | ~1.9 MB | | `clear-natural` | `clear-natural.on...
