DeepFilterNet3
DeepFilterNet3 is an open-source speech enhancement model that uses deep filtering to suppress noise in full-band audio at up to 48 kHz sampling rate. The neural network predicts dynamic suppression gains for each frequency bin, processing 20 ms frames with a 10 ms hop for real-time operation. It achieves high speech intelligibility (STOI 0.944) with minimal residual artifacts. Suitable for video call cleanup, podcast post-production, interview transcription preprocessing, and voice-over enhancement.

FAQ
How much does DeepFilterNet3 cost? Is it free?+
How does Layer's pricing work?+
There are no seat fees, feature gates, or plans on Layer. Instead, our platform uses a consumption based system with Creative Units (CUs) with a flexible monthly subscription. Every generation on Layer (image, video, 3D, or audio) consumes a Creative Unit, and you only pay for what you create.
