About DeepFilterNet 3

Cleans up noisy speech recordings. Provide the recording with `audio_url`, and the model removes background noise and upsamples the result. You can pick the output container with `audio_format` (mp3, aac, m4a, ogg, opus, flac or wav) and set `bitrate`, which defaults to 192k. The response includes the enhanced file and per-step timings.

Parameters

Send either the canonical name or the native name, not both. Canonical names
