DeepFilterNet vs DejaCode

DeepFilterNet is a free, open-source framework for speech enhancement on full-band 48 kHz audio, using deep filtering. Its command-line tool suppresses noise in WAV files, with 48 kHz as its only supported sampling rate. A LADSPA plugin provides real-time noise suppression and can be used with PipeWire filter chains to create a virtual microphone or audio output, including for VoIP apps such as Zoom or Discord. The plugin's minimum latency is 20 ms from STFT processing, plus any delay added by the LADSPA host. The Rust command-line tool defaults to DeepFilterNet2; the Python interface documents DeepFilterNet and DeepFilterNet2. An optional post-filter may slightly over-attenuate very noisy sections. The framework supports Linux, macOS and Windows, though training is tested only under Linux. The Python package installs as deepfilternet, and an optional train extra adds data-loading functionality for Linux training. Code is available under either the MIT License or Apache License 2.0.

DejaCode is an enterprise application for managing open-source license compliance and software supply-chain integrity across products and teams. It tracks open-source and third-party components, with unlimited products, components, and packages in each plan. Teams can store and manage SBOMs, retain historical records for audits, and import CycloneDX, SPDX, or AboutFile formats. Usage policies can be set at license or package level and linked with ScanCode; enforcement is advisory. Integrations include GitHub, GitLab, Jira Cloud, SourceHut, and Forgejo, with REST API and webhook options for other services. AboutCode connections include ScanCode.io for package scanning, PurlDB, and VulnerableCode for vulnerability data. Deployment documentation covers Docker, enterprise, and local development setups. For enterprise deployments, the guidance recommends running your own related service instances to avoid sending sensitive or private data to public endpoints. Team starts at $500 a month and Business at $1,500 a month, each billed annually at the start of the subscription period. Enterprise pricing is custom and not listed. A private evaluation instance with all features and support is available for 30 days.
