Sounds +that should come from above or below will still only play in 2D since there is +no height difference in the speaker array. + +To work around this, 3D7.1 was designed so that some speakers are placed higher +than the listener while others are lower, in a particular configuration that +tries to provide balanced output and maintain some compatibility with existing +audio content and software. Software that recognizes this setup, or can be +configured for it, can then take advantage of the height difference and +increase the perception of verticality for true 3D audio. The result is that +sounds can be perceived as coming from left, right, front, and back, as well as +up and down. + +[1] http://www.codemasters.com/research/3D_sound_for_3D_games.pdf + + +Hardware Setup +============== + +Setting up 3D7.1 requires an audio device capable of raw 8-channel or 7.1 +output, along with a 7.1 speaker kit. The speakers should be hooked up to the +device in the usual way, with front-left and front-right output going to the +front-left and front-right speakers, etc. The placement of the speakers should +be set up according to the table below. Azimuth is the horizontal angle in +degrees, with 0 directly in front and positive values go /left/, and elevation +is the vertical angle in degrees, with 0 at head level and positive values go +/up/. + +------------------------------------------------------------ +- Speaker label | Azimuth | Elevation | New label - +------------------------------------------------------------ +- Front left | 51 | 24 | Upper front left - +- Front right | -51 | 24 | Upper front right - +- Front center | 0 | 0 | Front center - +- Subwoofer/LFE | N/A | N/A | Subwoofer/LFE - +- Side left | 129 | -24 | Lower back left - +- Side right | -129 | -24 | Lower back right - +- Back left | 180 | 55 | Upper back center - +- Back right | 0 | -55 | Lower front center - +------------------------------------------------------------ + +Note that this speaker layout *IS NOT* compatible with standard 7.1 content. +Audio that should be played from the back will come out at the wrong location +since the back speakers are placed in the lower front and upper back positions. +However, this speaker layout *IS* more or less compatible with standard 5.1 +content. Though slightly tilted, to a listener sitting a bit further back from +the center, the front and side speakers will be close enough to their intended +locations that the output won't be too off. + + +Software Setup +============== + +To enable 3D7.1 on OpenAL Soft, first make sure the audio device is configured +for 7.1 output. Then in the alsoft-config utility, under the Renderer tab, +select the 3D7.1.ambdec preset for the 7.1 Surround decoder configuration. And +that's it. Any applications using OpenAL Soft can take advantage of fully 3D +audio, and multi-channel sounds will be properly remixed for the speaker +layout. + +Playback can be improved by (copying and) modifying the 3D7.1.ambdec preset, +changing the specified speaker distances to match the the real distance (in +meters) from the center of the speaker array, then enable High Quality Mode in +alsoft-config. That will improve the quality when the speakers are not all +equidistant. + +Note that care must be taken that the audio device is not treated as a "true" +7.1 device by non-3D7.1-capable applications. In particular, the audio server +should not try to upmix stereo and 5.1 content to "fill out" the back speakers, +and non-3D7.1 apps should be set to either stereo or 5.1 output. + +As such, if your system is capable of it, it may be useful to define a virtual +5.1 device that maps the front, side, and LFE channels to the main device for +output and disables upmixing, then use that virtual 5.1 device for apps that do +normal stereo or surround sound output, and use the main device for apps that +understand 3D7.1 output. diff --git a/docs/ambdec.txt b/docs/ambdec.txt new file mode 100644 index 00000000..1f328937 --- /dev/null +++ b/docs/ambdec.txt @@ -0,0 +1,189 @@ +AmbDec Configuration Files +========================== + +AmbDec configuration files were developed by Fons Adriaensen as part of the +AmbDec program <http://kokkinizita.linuxaudio.org/linuxaudio/index.html>. + +The file works by specifying a decoder matrix or matrices which transform +ambisonic channels into speaker feeds.

See docs/ambisonics.txt for more general information +about ambisonics. + +Starting with OpenAL Soft 1.18, version 3 of the file format is supported as a +means of specifying custom surround sound speaker layouts.

However, the format as OpenAL Soft sees it is as follows: + +The file is plain text. Comments start with a hash/pound character (#).

Counting up from the least significant bit, bit 0 maps to Ambisonic +Channel Number (ACN) 0, bit 1 maps to ACN 1, etc. As an example, a value of 'b' +enables bits 0, 1, and 3 (1011 in binary), which correspond to ACN 0, 1, and 3 +(first-order horizontal). + +/dec/freq_bands <count:int> +Specifies the number of frequency bands used by the decoder. This must be 1 for +single-band or 2 for dual-band. + +/dec/speakers <count:int> +Specifies the number of output speakers to decode to. + +/dec/coeff_scale <type:string> +Specifies the scaling used by the decoder coefficients.

However, +since OpenAL Soft needs to match a speaker definition to an output channel, the +speaker ID is used to identify what output channel it correspond to. Therefore, +OpenAL Soft requires these channel labels to be recognized: + +LF = Front left +RF = Front right +LS = Side left +RS = Side right +LB = Back left +RB = Back right +CE = Front center +CB = Back center + +Additionally, configuration files for surround51 will acknowledge back speakers +for side channels, and surround51rear will acknowledge side speakers for back +channels, to avoid issues with a configuration expecting 5.1 to use the side +channels when the device is configured for back, or vice-versa. + +Furthermore, OpenAL Soft does not require a speaker definition for each output +channel the configuration is used with. So for example a 5.1 configuration may +omit a front center speaker definition, in which case the front center output +channel will not contribute to the ambisonic decode (though OpenAL Soft will +still use it in certain scenarios, such as the AL_EFFECT_DEDICATED_DIALOGUE +effect). + + +Creating Configuration Files +============================ + +Configuration files can be created or modified by hand in a text editor. The +AmbDec program also has a GUI for creating and editing them.

This is a collection of +MATLAB and GNU Octave scripts that can generate AmbDec configuration files from +an array of speaker definitions (labels and positions). If you're familiar with +using MATLAB or GNU Octave, this may be a good option. + +There are plans for OpenAL Soft to include a utility to generate coefficients +and make configuration files. However, calculating proper coefficients for +anything other than regular or semi-regular speaker setups is somewhat of a +black art, so may take some time. diff --git a/docs/ambisonics.txt b/docs/ambisonics.txt new file mode 100644 index 00000000..2d94427e --- /dev/null +++ b/docs/ambisonics.txt @@ -0,0 +1,126 @@ +OpenAL Soft's renderer has advanced quite a bit since its start with panned +stereo output. Among these advancements is support for surround sound output, +using psychoacoustic modeling and more accurate plane wave reconstruction. The +concepts in use may not be immediately obvious to people just getting into 3D +audio, or people who only have more indirect experience through the use of 3D +audio APIs, so this document aims to introduce the ideas and purpose of +Ambisonics as used by OpenAL Soft. + + +What Is It? +=========== + +Originally developed in the 1970s by Michael Gerzon and a team others, +Ambisonics was created as a means of recording and playing back 3D sound. +Taking advantage of the way sound waves propogate, it is possible to record a +fully 3D soundfield using as few as 4 channels (or even just 3, if you don't +mind dropping down to 2 dimensions like many surround sound systems are). This +representation is called B-Format. It was designed to handle audio independent +of any specific speaker layout, so with a proper decoder the same recording can +be played back on a variety of speaker setups, from quadraphonic and hexagonal +to cubic and other periphonic (with height) layouts. + +Although it was developed decades ago, various factors held ambisonics back +from really taking hold in the consumer market. However, given the solid +theories backing it, as well as the potential and practical benefits on offer, +it continued to be a topic of research over the years, with improvements being +made over the original design. One of the improvements made is the use of +Spherical Harmonics to increase the number of channels for greater spatial +definition. Where the original 4-channel design is termed as "First-Order +Ambisonics", or FOA, the increased channel count through the use of Spherical +Harmonics is termed as "Higher-Order Ambisonics", or HOA. The details of higher +order ambisonics are out of the scope of this document, but know that the added +channels are still independent of any speaker layout, and aim to further +improve the spatial detail for playback. + +Today, the processing power available on even low-end computers means real-time +Ambisonics processing is possible. Not only can decoders be implemented in +software, but so can encoders, synthesizing a soundfield using multiple panned +sources, thus taking advantage of what ambisonics offers in a virtual audio +environment. + + +How Does It Help? +================= + +Positional sound has come a long way from pan-pot stereo (aka pair-wise). +Although useful at the time, the issues became readily apparent when trying to +extend it for surround sound. Pan-pot doesn't work as well for depth (front- +back) or vertical panning, it has a rather small "sweet spot" (the area the +head needs to be in to perceive the sound in its intended direction), and it +misses key distance-related details of sound waves. + +Ambisonics takes a different approach. It uses all available speakers to help +localize a sound, and it also takes into account how the brain localizes low +frequency sounds compared to high frequency ones -- a so-called psychoacoustic +model. It may seem counter-intuitive (if a sound is coming from the front-left, +surely just play it on the front-left speaker?), but to properly model a sound +coming from where a speaker doesn't exist, more needs to be done to construct a +proper sound wave that's perceived to come from the intended direction. Doing +this creates a larger sweet spot, allowing the perceived sound direction to +remain correct over a larger area around the center of the speakers. + +In addition, Ambisonics can encode the near-field effect of sounds, effectively +capturing the sound distance. The near-field effect is a subtle low-frequency +boost as a result of wave-front curvature, and properly compensating for this +occuring with the output speakers (as well as emulating it with a synthesized +soundfield) can create an improved sense of distance for sounds that move near +or far. + + +How Is It Used? +=============== + +As a 3D audio API, OpenAL is tasked with playing 3D sound as best it can with +the speaker setup the user has. Since the OpenAL API does not explicitly handle +the output channel configuration, it has a lot of leeway in how to deal with +the audio before it's played back for the user to hear. Consequently, OpenAL +Soft (or any other OpenAL implementation that wishes to) can render using +Ambisonics and decode the ambisonic mix for a high level of accuracy over what +simple pan-pot could provide. + +This is effectively what the high-quality mode option does, when given an +appropriate decoder configuation for the playback channel layout. 3D rendering +and effect mixing is done to an ambisonic buffer, which is later decoded for +output utilizing the benefits available to ambisonic processing. + +The basic, non-high-quality, renderer uses similar principles, however it skips +the frequency-dependent processing (so low frequency sounds are treated the +same as high frequency sounds) and does some creative manipulation of the +involved math to skip the intermediate ambisonic buffer, rendering more +directly to the output while still taking advantage of all the available +speakers to reconstruct the sound wave. This method trades away some playback +quality for less memory and processor usage. + +In addition to providing good support for surround sound playback, Ambisonics +also has benefits with stereo output. 2-channel UHJ is a stereo-compatible +format that encodes some surround sound information using a wide-band 90-degree +phase shift filter. It works by taking a B-Format signal, and deriving a +frontal stereo mix with the rear sounds attenuated and filtered in with it. +Although the result is not as good as 3-channel (2D) B-Format, it has the +distinct advantage of only using 2 channels and being compatible with stereo +output. This means it will sound just fine when played as-is through a normal +stereo device, or it may optionally be fed to a properly configured surround +sound receiver which can extract the encoded information and restore some of +the original surround sound signal. + + +What Are Its Limitations? +========================= + +As good as Ambisonics is, it's not a magic bullet that can overcome all +problems. One of the bigger issues it has is dealing with irregular speaker +setups, such as 5.1 surround sound. The problem mainly lies in the imbalanced +speaker positioning -- there are three speakers within the front 60-degree area +(meaning only 30-degree gaps in between each of the three speakers), while only +two speakers cover the back 140-degree area, leaving 80-degree gaps on the +sides. It should be noted that this problem is inherent to the speaker layout +itself; there isn't much that can be done to get an optimal surround sound +response, with ambisonics or not. It will do the best it can, but there are +trade-offs between detail and accuracy. + +Another issue lies with HRTF. While it's certainly possible to play an +ambisonic mix using HRTF and retain a sense of 3D sound, doing so with a high +degree of spatial detail requires a fair amount of resources, in both memory +and processing time. And even with it, mixing sounds with HRTF directly will +still be better for positional accuracy. diff --git a/env-vars.txt b/docs/env-vars.txt index b2268643..a973ee81 100644 --- a/env-vars.txt +++ b/docs/env-vars.txt @@ -79,3 +79,13 @@ which some applications make use of to protect against partial updates.

This is followed by an unsigned 32-bit integer, specifying the +sample rate the data set is designed for (OpenAL Soft will not use it if the +output device's playback rate doesn't match). + +Afterward, an unsigned 8-bit integer specifies how many sample points (or +finite impulse response filter coefficients) make up each HRIR. + +The following unsigned 8-bit integer specifies the number of fields used by the +data set. Then for each field an unsigned 16-bit short specifies the distance +for that field (in millimeters), followed by an 8-bit integer for the number of +elevations. These elevations start at the bottom (-90 degrees), and increment +upwards. Following this is an array of unsigned 8-bit integers, one for each +elevation which specifies the number of azimuths (and thus HRIRs) that make up +each elevation. Azimuths start clockwise from the front, constructing a full +circle. Mono HRTFs use the same HRIRs for both ears by reversing the azimuth +calculation (ie. left = angle, right = 360-angle). + +The actual coefficients follow. Each coefficient is a signed 16-bit or 24-bit +sample. Stereo HRTFs interleave left/right ear coefficients. The HRIRs must +be minimum-phase. This allows the use of a smaller filter length, reducing +computation. For reference, the default data set uses a 32-point filter while +even the smallest data set provided by MIT used a 128-sample filter (a 4x +reduction by applying minimum-phase reconstruction). + +After the coefficients is an array of unsigned 8-bit delay values, one for +each HRIR (with stereo HRTFs interleaving left/right ear delays). This is the +propagation delay (in samples) a signal must wait before being convolved with +the corresponding minimum-phase HRIR filter. diff --git a/examples/alffplay.c b/examples/alffplay.c deleted file mode 100644 index 17f6d3bc..00000000 --- a/examples/alffplay.c +++ /dev/null @@ -1,1533 +0,0 @@ -/* - * alffplay.c - * - * A pedagogical video player that really works!

This is followed by an unsigned 32-bit integer, specifying the -sample rate the data set is designed for (OpenAL Soft will not use it if the -output device's playback rate doesn't match). - -Afterward, an unsigned 8-bit integer specifies how many sample points (or -finite impulse response filter coefficients) make up each HRIR. - -The following unsigned 8-bit integer specifies the number of elevations used -by the data set. The elevations start at the bottom (-90 degrees), and -increment upwards. Following this is an array of unsigned 8-bit integers, one -for each elevation which specifies the number of azimuths (and thus HRIRs) that -make up each elevation. Azimuths start clockwise from the front, constructing -a full circle for the left ear only. The right ear uses the same HRIRs but in -reverse (ie, left = angle, right = 360-angle). - -The actual coefficients follow. Each coefficient is a signed 16-bit sample, -with each HRIR being a consecutive number of sample points. The HRIRs must be -minimum-phase. This allows the use of a smaller filter length, reducing -computation. For reference, the built-in data set uses a 32-point filter while -even the smallest data set provided by MIT used a 128-sample filter (a 4x -reduction by applying minimum-phase reconstruction). Theoretically, one could -further reduce the minimum-phase version down to a 16-point filter with only a -small reduction in quality. - -After the coefficients is an array of unsigned 8-bit delay values, one for -each HRIR.

The presets are prepared to work with OpenAL Soft's high +quality decoder. By default all of the speaker distances within a preset are +set to the same value, which results in no effect from distance compensation. +If this doesn't match your physical speaker setup, it may be worth copying the +preset and modifying the distance values to match (note that modifying the +azimuth and elevation values in the presets will not have any effect; the +specified angles do not change the decoder behavior). + +Details of the individual presets are as follows. + +square.ambdec +Specifies a basic square speaker setup for Quadraphonic output, with identical +width and depth. Front speakers are placed at +45 and -45 degrees, and back +speakers are placed at +135 and -135 degrees. + +rectangle.ambdec +Specifies a narrower speaker setup for Quadraphonic output, with a little less +width but a little more depth over a basic square setup. Front speakers are +placed at +30 and -30 degrees, providing a bit more compatibility for existing +stereo content, with back speakers at +150 and -150 degrees. + +itu5.1.ambdec +Specifies a standard ITU 5.0/5.1 setup for 5.1 Surround output. The front- +center speaker is placed directly in front at 0 degrees, with the front-left +and front-right at +30 and -30 degrees, and the surround speakers (side or +back) at +110 and -110 degrees. + +hexagon.ambdec +Specifies a flat-front hexagonal speaker setup for 7.1 Surround output. The +front left and right speakers are placed at +30 and -30 degrees, the side +speakers are placed at +90 and -90 degrees, and the back speakers are placed at ++150 and -150 degrees. Although this is for 7.1 output, no front-center speaker +is defined for the decoder, meaning that speaker will be silent for 3D sound +(however it may still be used with AL_SOFT_direct_channels or ALC_EXT_DEDICATED +output). A "proper" 7.1 decoder may be provided in the future, but due to the +nature of the speaker configuration will have trade-offs. + +3D7.1.ambdec +Specifies a 3D7.1 speaker setup for 7.1 Surround output.
