    The SoX Resampler library

    The SoX Resampler library

    High quality, one-dimensional sample-rate conversion library

    The SoX Resampler library `libsoxr' performs one-dimensional sample-rate conversion—it may be used, for example, to resample PCM-encoded audio. It aims to give fast and high quality results for any constant (rational or irrational) resampling ratio. Phase-response, preserved bandwidth, aliasing, and rejection level parameters are all configurable; alternatively, simple `preset' configurations may be selected. An experimental, variable-rate resampling mode of operation is also included.

    Linux Studio Plugins Project

    LSP (Linux Studio Plugins) is a collection of open-source plugins currently compatible with LADSPA, LV2 and LinuxVST formats. Standalone plugins for JACK are provided since version 1.0.8.

After some contributions to other open source projects the decision was made to implement separate and independent plugin distribution.

    File Order Randomizer

    For cheap music players: Puts random numbers in front of every file.

    If, like me, you have a car radio or a clock radio which cannot play tracks in random order from your usb stick itself, this application might be useful for you. It generates random numbers and puts them in front of every file in a specified folder. So all you've got to do when you want a new play order for your music tracks is run this application.

    Internet Friendly Media Encoder

    Internet Friendly Media Encoder

    Simple, Flexible & Powerful H.265/HEVC video encoder!

    HEVC was developed with the goal of providing twice the compression efficiency of the previous standard, H.264 / AVC. Although compression efficiency results vary depending on the type of content and the encoder settings, at typical consumer video distribution bit rates HEVC is typically able to compress video twice as efficiently as AVC. End-users can take advantage of improved compression efficiency in one of two ways (or some combination of both); IFME helps you to organized, manage queue, manage plugins, and choose compiled x265 and more! Support AviSynth natively with build-in awesome library like InterFrame & Script Editor
