foo_dsp_stereoconv ~ Natural Headphone Crossfeed


​Natural crossfeed Foobar2000 component designed to give a realistic crossfeed / speaker simulation effect on headphones or earphones while producing a wide soundstage and zero sound coloration.

Simulates speakers spaced 30+30 degrees apart (classic stereo setup with better front projection of imaging) or 50+50 degrees apart (widened stereo setup with more similarity to classic headphone soundstage width)

Update 2016-07-26: I’ve put the “secret” update in public as v2.1, containing a new set of impulses. They also come in 30+30 degree and 50+50 degree versions but are derived from actual measurements around my head.

Ultimate Mono2Stereo ~ Better Mono To Stereo


What sets this frontend for ffmpeg apart from other stereo simulators is it creates an illusion of actual stereo separation. More importantly, it produces none of the weird phasing, and/or time delay artifacts. And very little, if any of the tone discoloration, when those others aren’t meticulously set up just right. All this is accomplished by using the ffmpeg crossover audio filter to split the sound into 8 frequency bands. The split points are based on center frequencies of a typical 1/3 octave equalizer. Those 8 bands are then panned in varying degrees to left and right. The varying width of each band is set to achieve the best balance between the left and right channels.

DR14 T.meter ~ Linux Dynamic Range Meter


DR14 T.meter is a free and open source command line tool for computing the Dynamic Range of your music according to the procedure used in the off-line meter released by the Pleasurize Music Foundation.

This tool is a very useful measure of how loud your music is, and for understanding that a good quality album always has a wide dynamic range, and it’s also useful for understanding the effects of the so called ‘loudness war’.

Dr14 t.meter is released under the terms of the GNU GPLv3 license and is intended for the Linux users who can not use the Windows application released by the Pleasurize Music Foundation, or the plugin for Foobar2000.

I’ve largely tested this application and it has always returned results identical to those of the official off-line meter.

Feature:
  • Compute the DR dynamic range of the audio file
