PulseEffects

Limiter, compressor, reverberation, stereo equalizer and auto volume effects for Pulseaudio applications

Order of effects applied to applications output:

1. Input Limiter (Ladspa Fast Lookahead Limiter)
2. Auto Volume
3. Stereo Panorama (Gstreamer)
4. Compressor (Ladspa SC4)
5. Freeverb (Gstreamer)
6. Equalizer Input Gain (Gstreamer volume)
7. Butterworth Highpass filter (Gstreamer audiocheblimit)
8. Butterworth Lowpass filter (Gstreamer audiocheblimit)
9. 15 bands Equalizer (Gstreamer)
10. Equalizer Output Gain (Gstreamer volume)
11. Output Limiter (Ladspa Fast Lookahead Limiter)
12. Spectrum Analyzer (Gstreamer)

Since version 2.0.0 PulseEffects is capable of applying effects to microphone output at the same time it applies them for applications output:

1. Input Limiter (Ladspa Fast Lookahead Limiter)
2. Compressor (Ladspa SC4)
3. Freeverb (Gstreamer)
4. Equalizer Input Gain (Gstreamer volume)
5. Butterworth Highpass filter (Gstreamer audiocheblimit)
6. Butterworth Lowpass filter (Gstreamer audiocheblimit)
7. 15 bands Equalizer (Gstreamer)
8. Equalizer Output Gain (Gstreamer volume)
9. Output Limiter (Ladspa Fast Lookahead Limiter)
10. Spectrum Analyzer (Gstreamer)

Installation

Users upgrading from 1.x to 2.x will have to rebuild their presets. Since version 2.0.0 PulseEffects uses a different format. This change was necessary to support presets for microphone processing.
