rePhase is a FIR generation tool for building fully linear-phase active crossovers with arbitrary slopes.

It also let you manually compensate for the phase shifts of your loudspeakers and existing crossovers, be it active or passive.

Once generated, the FIR can be applied using any hardware (openDRC, miniSHARC, Najda, ...) or software (foobar, convolver, JRiver, ...), stereo or multi-way convolution engine.

Features

  • manual corrections only: power to the user
  • generate impulse responses (FIR) for convolution engines
  • measurement import and real-time manual correction
  • loudspeakers phase linearization (passive or active crossovers)
  • linear-phase and minimum-phase gain paragraphic EQ and shelving
  • constant-gain phase praragraphic EQ
  • multiple gain EQ algorithms (constant Q, proportional Q, constant shape, raised cosine)
  • arbitrary slopes linear-phase filters (Linkwitz-Riley, Brickwall, Horbach-Keele, etc.)
  • arbitrary slopes minimum-phase filters (Linkwitz-Riley, Butterworth, etc.)
  • generalized Linkwitz Transform mechanism ("compensate" mode)

Infrastructure and application monitoring for Azure Icon

Monitor your Azure® infrastructure, application, and systems performance side by side in a single enterprise-monitoring tool

So, you moved your applications and servers to Azure, but are they running any better and are you able to justify the investment? Without proper monitoring, you’re left guessing if application and server performance has improved, and when issues arise, you’re left scrambling to locate the root cause. SolarWinds® Server & Application Monitor (SAM) can monitor your Azure workloads side by side with your on-premises workloads to help ensure optimal application performance.
