Free Audio Plugins & Softwares for Linux

LSP Slap-back Delay – Slapback Delay plugin series

LSP Slap-back Delay – Slapback Delay plugin series is a free delay VST, LV2, Ladspa plugin developed by Linux Studio Plugins Project. Compatible OS(s): Linux.

This plugin allows to add set of short delays of the original signal to the output mix. Each delay can be used to simulate the early reflections of the signal from walls. This allows to make the stereo image of the original signal wider, and the position of the source more definitive in the mix. Equalizers provided for each delay line allow to simulate the fading of the original signal. Every delay can be set in both time and distance units. Also common pre-delay and time-stretching mechanisms are provided to allow the stereo image to change dynamically.

Remember that for more realistic picture the more delay is the more low and high frequencies are cut from the delayed signal.

LSP Room Builder plugin series

LSP Room Builder plugin series is a free reverb VST, LV2 plugin developed by Linux Studio Plugins Project. Compatible OS(s): Linux.

This plugin allows to simulate impulse response of any modelled room or space. The basic principle is based on generating of unit audio impulse and then capturing all it’s reflections from environment by special capturing objects that simulate microphone capsules.

So, in fact, this algorithm is a kind of raytracing algorithm but instead of single rays it performs tracing of ray groups. This allows to simulate large spaces withous significantly loose in quality and precision.

LSP Profiler plugin series

LSP Profiler plugin series is a free audio and studio utility VST, LV2 plugin developed by Linux Studio Plugins Project. Compatible OS(s): Linux.

A simple plugin for audio systems profiling. The profiling is performed by an algorithm based on the Synchronized Swept Sine method by Antonin Novak.

The profiler plugin allows to profile audio systems. These properties of an audio system can be currently profiled:

Latency.

Linear Impulse Response.

Nonlinear Characteristics.

LSP Phasendetektor – Phase Detector

LSP Phasendetektor – Phase Detector is a free audio and studio utility Stand Alone, VST, LV2, Ladspa plugin developed by Linux Studio Plugins Project. Compatible OS(s): Linux.

This plugin allows to detect phase between two sources. For example, for two or more microphones set at the different positions and distances from the sound source.

The internal algorithm is based on correlation function calculation between two sources.

Be aware: because there are many correlation functions for different phases calculated at one time, the entire analyzing process can take a lot of CPU resources. You can also reduce CPU utilization by lowering the maximum analysis time.

The plugin bypasses input signal without any modifications, so it can be placed everywhere it’s needed.

LSP Parametrischer Entzerrer – Parametric Equalizer plugin series

LSP Parametrischer Entzerrer – Parametric Equalizer plugin series is a free equalizer VST, LV2, Ladspa plugin developed by Linux Studio Plugins Project. Compatible OS(s): Linux.

This plugin performs parameteric equalization of input signal. Configurations with 16 and 32 filters are available for signal processing simultaneously.

LSP Latency Meter plugin

LSP Latency Meter plugin is a free audio and studio utility VST, LV2, Ladspa plugin developed by Linux Studio Plugins Project. Compatible OS(s): Linux.

A simple plugin that allows to measure the latency of a transmission line by using chirp – inverse filter convolution. Latency is determined as the lag of the convolution peak.

To measure the latency, first connect output of the plugin to the input of the transmission line. Then connect the output of the transmission line to the input of the plugin. Then you’re ready to press the Measure button. The plugin will generate short chirp signal on the output and await the response on the input. If the signal will be captured and detected on the input of the plugin, it will display the overall latency value.

LSP Kompressor – Compressor plugin series

LSP Kompressor – Compressor plugin series is a free compressor VST, LV2, Ladspa plugin developed by Linux Studio Plugins Project. Compatible OS(s): Linux.

This plugin performs compression of stereo input signal. Flexible sidechain-control configuration and additional sidechain inputs are provided. Different types of compression are possible: downward, upward and parallel. Also compressor may work as limiter in Peak mode with high Ratio and low Attack time.

LSP Impulsnachhall – Impulse Reverb plugin series

LSP Impulsnachhall – Impulse Reverb plugin series is a free reverb VST, LV2, Ladspa plugin developed by Linux Studio Plugins Project. Compatible OS(s): Linux.

This plugin performs highly optimized real time zero-latency convolution to the input signal. It can be used as a cabinet emulator, some sort of equalizer or as a reverb simulation plugin. All what is needed is audio file (s) with impulse response taken from the linear system (cabinet, equalizer or hall/room).

Unlike the Impulsantworten (Impulse Responses) plugin series, this plugin allows to apply the True Stereo Reverberation to the input signal.

To apply True Stereo Reverberation, the left input channel should be convolved with the left and right channels from the first impulse response fila and the right input channel is convolved with the left and right channels from the second impulse response file. The two output convolutions’ respective left and right components should be then summed into a single stereo output. This configuration is necessary to take full advantage of true stereo impulse responses. True stereo impulse responses are required to be provided as two separate stereo files.

By default, all controls of convolvers are set up to implement true stereo reverberation by setting left and right channels of first input file as input source for convolvers 0 and 1, and also setting left and right channels of second input file as input source for convolvers 2 and 3.

To use simple stereo reverberation on default settings, the left channel of input file can be set as source of convolver 0 and the right channel of input file can be set as source of convolver 3.
