    Chord Reporter

    Linux program displays the names of musical chords as you play them.

    Chord Reporter (hereafter abbreviated to CR) is a software program that displays the names of chords, as you play them (upon some MIDI controller or from a MIDI sequencer track). CR comes in two versions. There is an LV2 plugin that will run on any Linux program that loads such plugins. In that way, you can anaylze the chord progressions in your DAW's MIDI tracks. The second version is a Linux executable that runs on its own. You can directly attach your MIDI controller to this version...

    mp3respectr

    Weakening effect on the MP3 audio encoder

    Weakening effect on the MP3 audio encoder and the assimilation of the spectral characteristics of the source. Produced by applying empirical filter (derived from an analysis of a pair of flac-mp3) to the sound in the space R2. 1) Transfer the sound of the space R to R2 (mp3rsrr2); 2) Finding the empirical filter by OLS pair flac-mp3 (mp3rsols); 3) Apply a filter to the sound (mp3rsvalue); 4) Transfer the sound of the space R2 in space R (mp3rsr2r);
