Its purpose is to decode surround information from your stereo music (including mp3, of course), and to produce 5.1 output from it. It works with any stereo music containing surround info in a coding scheme compatible with any the following decoders: - Dolby Surround - Dolby ProLogic - Dolby ProLogic II - SRS CircleSurround - SRS CircleSurround II - DTS Neo:6 - Lexicon Logic7 - Stereo Quadrophonic (SQ) * - Quadrophonic Stereo (QS) It will also faithfully play back your 'plain old' stereo music, with the exception that echoes are usually played over the surround speakers, and some sound sources, usually strongly distorted guitars, choirs etc., tend to surround the listener instead of being played over the front speakers alone. Download The plugin is attached at the bottom of this post. Operation notes In contrast to the other foobar2000 surround processors (Channel Mixer, Matrix Mixer and ATSurround Processor, as of Aug. 2008), FreeSurround provides independently steered surround channels, and very low crosstalk between channels. If your want to check the state of your surround decoders, you find a test mp3 file at the bottom of the post. It will play a voice on your left front, left rear, right rear, right front and center speaker (one speaker at a time) -- if your decoder is good; otherwise there will be some mishmash on the other channels. Also, FS, being a surround decoder, should not be confused with DSP effects which merely give you an enriched stereo experience, such as Creative CMSS 3D and foobar's Convert Stereo to 4 Channels, or common DSPs like Stadium, Hall etc. Nevertheless there are some options to upmix plain stereo content meaningfully. Configuration notes** Here is a screen shot of the default settings in the config dialog (these happen to be also the settings that I use at home). The default settings are good for many surround setups, but there are some tweakable options (see screen shot). The sound field right after the decoding stage can be pictured as a 2-dimensional square with the listener at its center; this sound field can be further transformed spatially in several ways. The default setting is to leave the decoded field as it is, i.e., if a stereo track was downmixed from a discrete 5.1 track (e.g., from AC3 format) and is upmixed again with FreeSurround, it comes closest to the original source material when using the default settings. However, music that was not originally meant for surround playback can be spiced up quite a bit using these controls. The first option (Panorama) is to wrap the sound field around the listener in a circular manner. The slider allows to change the angle that the front soundstage takes up (i.e., the line between the front left and the front right corner of the sound field). Originally it is 90 degrees, but if it is set to, say, 270 degrees the front stage will be wrapped from behind the left ear along the front to behind the right ear of the listener. While the front stage is expanded, the side and rear sound field must correspondingly be compressed into the remaining space behind the listener. The second option (Dimension) allows to shift the sound field forward or backward without changing the shape. The third option (Depth) essentially scales the sound field to the back, i.e. the original square is resized along one axis (while the front stage stays where it is). These transforms are applied in the order in which they are listed here (the order matters). The last slider (Focus) is a bit experimental -- it allows to change the angular spread of the individual sound sources, either by making them more focal or less (i.e., more ambient). This is only really noticable with lots of speakers, but I would not overdo it. The second group of controls is how the sound field is mapped onto the speakers. The first setting here is the channel setup; this allows you to select how many speakers you have and where they are placed (front left and right, center, rear left and right, side speakers, etc.). From the point of view of the decoder there at 16 possible positions along the edges of the square sound field (see this picture for an example), namely the 4 corners, the 4 midpoints (front center, back center, left side, and right side), and two positions on each edge half-way between the corners and the midpoint (e.g., front left center, front right center). Most people have only a subset of all these channels (e.g., 7.1) in some common locations, but you can have some fairly arbitrary setups (*). But note that the placement of the speakers in the room is actually not in a rectangle but instead follows the corresponding home theater rules. If you have a subwoofer you might want to do the bass management right here, but it is usually a better idea to let the sound card or amplifier do it if they offer the option (e.g. for active sub-satellite systems). The last option in this box is the stereo separation; this allows to effectively stretch the sound field horizontally in the front and/or back areas. Change log** 0.9.0 - fixed a steering bug in the 0.8.1 beta (sound field was shifted by a few degrees to the left due to an oversight; also steering was less accurate than it should have been) - removed a library dependency (boost serialization) that could cause conflicts with other plugins using the same library but different version (to be confirmed as fixed) 0.8.1 (beta) - basically a rewrite & cleanup; see this post for more details on the original beta announcement. - supports more speaker arrangements (up to 16.1) - supports more controls for sound field transformations (shift, stretch, wrap, ...) - probably a bit faster, too 0.3.5 - now much faster when switching tracks 0.3.4 - new front and rear stereo separation controls - 4 phase shifting modes are supported now - new linear steering mode (better than the old one) - fixed the dimension slider (negative values were mapped to 0) - the gain is back at 100% due to request (you can still put the equalizer before FS to control the gain) 0.3.3 - added the option to invert the rear phase (like pl2 movie mode) - added the option to specify the (surround) mixing coefficients which are assumed for decoding pre-0.3.3 - changed "center width" into "center image", which controls how present the center speaker is (0.3-0.7 are good values for music). - expanded the range of "dimension" to [-0.5 .. 1.0] where 0 is a normal surround soundfield, -0.5 moves the sound towards the front, 1.0 moves it backwards. - changed the gain to ~85% to avoid clipping in practically all cases. - fixed center/surround level (both were too loud it appears). * SQ is decoded with mono surrounds (i.e. like ProLogic I), due to a defective coding specification. QS requires the front stereo separation to be set to 1.5, or else the sound field will be too narrow. * There is one little catch with the more exotic channels: foobar2000 (or Windows) do not expose some of the rarely used positions but instead allow to connect "top" speakers (meant for the ceiling). Therefore there is a bit of remapping going on for these positions: If you have 'side front left'/'side front right' speakers, connect them to the 'top front left'/'top front right' channels, if you have 'side back left/right' connect them to 'top back left/right', and if you have 'back center left/right' speakers you need to connect them to the 'top front center' and 'top back center' channels, respectively.

I haven't checked into bit-depth just yet, just 16-bit mono and stereo at different sample rates... This post has been edited by Googer: Feb 5 2007, 21:55

Btw: It works with 32bit floating point precision internally, so bitrates should be no problem.

Interestingly I configured foo_gep to output at 22 KHz as a test and tried some nsf files (so its output should also have been 22 KHz mono) and had no problems with seeks... And here's the contents of failure.txt (and yes this is with fsurround as the only active DSP to try to cut down on potential failure points ): CODE Illegal operation: Code: C0000005h, flags: 00000000h, address: 0149480Ah Access violation, operation: read, address: 00000000h Call path: playback_process entry=>dsp::flush This is the first crash logged by this instance.

Group: Developer Posts: 97 Joined: 6-June 06 Member No.: 31515	QUOTE (Googer @ Feb 6 2007, 17:43) Thanks for the quick fix, though I have another bug to report - with a 22 KHz mono mp3 (the htguys.com podcast to be specific), foobar2000 crashes in foo_dsp_fsurround upon seeking. Interestingly I configured foo_gep to output at 22 KHz as a test and tried some nsf files (so its output should also have been 22 KHz mono) and had no problems with seeks... <snipp> Thanks for the detailed info, it's fixed now. The bug was that the decoder core is not loaded in bypass mode (i.e. non-stereo source), but was flushed upon seeking.
