BruteFIR ~ Unix Multi-Channel Convolution


BruteFIR is a software convolution engine, a program for applying long FIR filters to multi-channel digital audio, either offline or in real-time. Its basic operation is specified through a configuration file, and filters, attenuation and delay can be changed in runtime through a simple command line interface. The FIR filter algorithm used is an optimized frequency domain algorithm, partly implemented in hand-coded assembler, thus throughput is extremely high. In real-time, a standard computer can typically run more than 10 channels with more than 60000 filter taps each.

Through its highly modular design, things like adaptive filtering, signal generators and sample I/O are easily added, extended and modified, without the need to alter the program itself.

BitterSweet ~ Transient Designer


BitterSweet v3 is Flux:: acclaimed transient processor used by hundreds of thousands of users for audio transient management with the simple turn of a knob – Turning it to the Sweet side reduces the transients, and turning it to the Bitter side magnifies the transients – No dongle or license activation required – 100% Freeware!

Features:

  • Up to 8 channels Input / Output
  • Output Gain
  • Controls the Output Gain at the end of the processing (-/+ 12 dB).
  • Link to Output Gain – Compensates the Output Gain depending on the Transient Amount in order to achieve unity gain.
