Audio ToolKit is a set of audio filters. It is supposed to help assemble workflows for specific audio processing.
Audio Toolkit is published under the BSD license.
- Fixed the FFT implementation
- Added a fast zero latency convolution filter with tests and comparison with a basic FIR implementation
- Enhanced global framework performance (Core, EQ, Tools)
- Enhanced dynamic gain filters behavior by switching between LUT or direct computation dependening on the LUT state
- Added override and final keywords in virtual calls
- Changed the API so that process_impl is now const
- Exposed full_setup to the user (direct reset of the internal state, already called when changing sample rate)
- Added LinkWitz-Riley second order low and high path filters
- Fix resetting the internal state of all delays by using full_setup
- Added a CustomFIRFilter with Python wrapper
- Added time-varying IIR filters (variable frequency, coded as transposed direct form II)
- Added second order time varying filter implementations
- Added a RelativePowerFilter with Python wrappers
- Added a DerivativeFilter with Python wrappers
- Added Python wrappers for the InWavFilter
- Fixed some warnings during compilation
- Renamed slope attribute to ratio for Gain Compressor and Expander Filters
- Renamed the Chamberlin filter
- Added a StereoUniversalFixedDelayLineFilter that can make mix two channels together with different delay for each channel with Python wrappers
- Added a GainLimiterFilter (maximum ratio) with Python wrappers
- Added a MaxFilter with Python wrappers
- Added a DryWetFilter with Python wrappers
- Bug fixes
- Added a PipelineGlobalSinkFilter with Python wrapper
- Changed the MiddleSideFilter scale (no more dividing by 2 in the code)
- Additional tools additions (cos generator, offset+volume filter)
- Added a second order all pass filter with Python wrappers
- Added a white noise generator filter
- Fixed the delay line filters
- Fixed second order EQ Python wrappers
- Added a fixed delay line filter (FIR filter) with Python wrappers
- Added an universal fixed delay line filter (FIR, IIR and all-pass filter + combinations) with Python wrappers
- Added variable delay filters (delay is given on an additional port)
- Adding compressor elements and the Python wrappers
- Fixed Python wrappers by adding default number of port/channels
- Added restrict pointer support in all filter that can benefit from this
