DSP components
|
This started out as sort of a toy plugin containing DSPs for differentiation (input f(t), output f'(t)) and integration (input f(t), output F(t)) Recently a DSP for playback of f(t)+f'(t) has been added, in layman's terms this enhances treble / noise / transient content and can be seen as the audio equivalent of image sharpening filters. |

Other surround plug-ins may claim to provide Dolby® Pro Logic® II capable decoding, but only ATSurround can deliver true high-quality matrix decoding with excellent channel leak rejection and headphone virtualization within its class. We encourage you to listen for yourself and hear the difference. It's more than just an upmixer. - Enjoy your music in true surround and make full use of your 5.1 system. - Immerse yourself in virtual-surround with the Headphone decoding mode. - Compatible with Dolby® and similar processors. ATSurround extracts the encoded surround information in your music and enables it to be played in full surround. The ATSurround Headphone decoding mode allows the listening of audio sources which sound like they're really coming from a live 5-point surround system. Music no longer sounds like it's "inside" your head, listening fatigue is thus reduced. The ATSurround Encoder mode is capable of performing surround audio encoding to stereo. This stereo output may be distributed via any 2-channel medium, such as CD-Audio, MP3, or directly to an external audio receiver which performs audio surround decoding, useful when the receiver is connected using a stereo cable. |

You only need a WinXP PC equipped with a multichannel sound card (e.g. a 5.1 or 7.1 surround sound card), that drives the various voices of an amplifier/loundspeaker active configuration setup (ie: without passive crossover only tweeter protection capacitors) fed by this plugin and foobar2000. Obviously the source must be .wav files ripped from CDs for example. I am not talking about MP3 here, obviously, but that would work as well. In fact, if some of you have downloadable high resolution .wav files with interesting music, I am interested. In theory, the plugin should be working even at 192K Samples/Sec, 24 bits, if your sound card supports it. The plugin implements a crossover and the following specification are for the features that are currently working. - Stereo - 4 voices or less - Filters: Butterworth, Bessel, Chebyshev - Type: Low Pass, High Pass, Band Pass - Order: 1 to 8 - Filter frequencies: 1-20000 Hz - Gain control per voices - Re-routing per voice to the various outputs - Mute control per voice |

This component wraps the functionality of a Dolby Headphone engine DLL (typically DOLBYHPH.DLL bundled with some software DVD players) to be used under foobar2000. After instalation you must configure the plugin pointing out the location of that DLL in your system and restart foobar2000. Amplification is provided by the Dolby Headphone engine itself. Dynamic Compression is disabled by default as of version 1.1.1. Enjoy! Tested with DOLBYHPH.DLL version 1.10.0.270. |

To use it, you must own the PL2XDLL.dll (put it in the foobar2000 or Windows\system32 directory). There are at least 2 versions of this file, and I recommend the newer v.3.0.0.2723 (which seems to be a major rewrite). Of course, I will not point you to the source of that dll ;-) Notes: It will upmix any stereo source to 5.1, but the LFE channel will stay empty. So, if you need bass redirection, you should enable it in your soundcard's settings. You can also use it to get surround on your headphones, either if you put foo_dsp_atsurround after it (in the Headphone mode) or foo_dsp_dolbyhp. Of course, you can also take ATSurround's built-in upmixing instead of PL2. What sounds better depends mostly on the type of music and personal taste. |

The only free surround processor for Foobar 2000 which can properly decode Dolby ProLogic I/II compatible surround channels from stereo music (in contrast to effect plugins which simply copy the front channels to create surround or DSPs which just implement the basic Dolby Surround/ProLogic functionality). Therefore it is at least on par with Dolby ProLogic II, SRS CircleSurround II and DTS:Neo 6. This supersedes the older Dolby Pro Logic II Wrapper, which relied on commerical software and did not sound as neutral as Free Surround does. Note: This plugin requires another DLL, namely libfftw3f-3.dll which has to be placed directly in the foobar2000 directory (not in the components directory). You find it on FreeSurround's homepage, too. Another Note: If you have a subwoofer-satellite system you need to enable bass redirection in your soundcard or let the ChannelMixer DSP do the bass redirection by chaining it behind FreeSurround. |

his DSP component takes impulse response and does a fast convolution of the sound data with that impulse response. Basically, it allows quick computation of any combination of linear effects, such as equalization, echo, flange, reverb, phase shift and so on. It can transform the sound to exactly the image you would get as where the impulse response was recorded, allowing you to get an accurate reproduction of a big theather or stadium. This effect is available as 'Acoustic Mirror' in Sound Forge. A restricted version is available as 'Digital Convolution' in Cool Edit. |

Now a skip silence DSP is already included in the foobar2000 standard DSP array. So you won't need this plug-in if you use a version of foobar2000 after 0.9.5.4 It skips silence... |

Obsolete version: incompatibility with the latest release. Needs SDK update. The classic "vocal cut" filter, except that the output is stereo instead of mono. This is accomplished through FFT phase analysis. This version includes recently discovered algorithm improvements to reduce echo and eliminate clicking. |
