    PulseEffects is a free and open-source GTK application relaying on GStreamer for applying effects to input and output audio streams, intended to be used in conjunction with PulseAudio sound server.[4]

    It is published under the GNU GPLv3 license.[3]

    Output effects

    The application has various available effects[4] in the form of plugin made by different developer teams.[5] Autogain implementing EBU R128 standard for audio normalization[6] is based on libebur128 library.[7]

    Bass enhancer to handle with missing fundamental,[8] exciter to enhance the signal by dynamic equalization,[9] deeser to dynamically reduce high frequencies,[10] filter to boost or cut some frequency ranges,[11] gate (single[12] and multiband)[13] to reduce disturbing noise, signal limiter,[14] multiband compressor,[15] reverbation,[16] and stereo tools[17] are provided by Calf Studio Gear.

    Convolver is based on zita-convolver library.[18] Compressor (to reduce dynamic range),[19] delay[20] and equalizer[21] are Linux Studio plugins.

    Crossfeed effect based on bs2b library is provided by GStreamer,[22] loudness to adjust low frequencies volume is based on mda-vst plugin ported to LV2 format,[23] maximixer to limit or raise the average level of an audio source without clipping is developed by ZAM Audio,[24] crystalizer plugin to enhance dynamic range is provided by FFmpeg[25] and pitch shift is based on Rubber Band library.[26]

    Input effects

    Amongst input effects, there are WebRTC plugin developed by GStreamer[27] and a subset of already available effects for output audio stream: compressor, deeser, equalizer, filter, gate, limiter, multiband compressor, multiband gate, pitch shift and reverbation.[4]
