DeepFilterNet: what it does well

  • Free and open source under MIT or Apache 2.0.
  • Real-time suppression is available through a LADSPA plugin.
  • PipeWire filter chains can create a virtual microphone.
  • Framework supports Linux, macOS, and Windows.
  • Precompiled binaries and a Python wheel are available.

What to know first

  • Command-line processing currently supports only 48 kHz audio.
  • Training is tested only under Linux.
  • LADSPA processing adds at least 20 ms latency plus host delay.
  • Post-filter may over-attenuate very noisy sections.

FluentMigrator: what it does well

  • C# migrations define both apply and rollback methods.
  • Supports providers including SQL Server and PostgreSQL.
  • CLI can validate migrations before execution.
  • CI/CD examples cover GitHub Actions, Azure DevOps, and Jenkins.

What to know first

  • Requires .NET 8.0 or later.
  • Provider packages must be selected separately.
  • Requires a supported database and basic C# knowledge.
