* Use function pointers to call the source mixerChris Robinson2011-05-061-99/+52
|
* Use signed samples for 8-bit storageChris Robinson2011-05-051-57/+56
|
* Combine the mono and multi-channel mixer templatesChris Robinson2011-05-031-314/+51
|
* Use the same filters for mono sources and multi-channelChris Robinson2011-05-031-12/+12
|
* Mark some mixer pointers as restrictedChris Robinson2011-05-021-27/+27
|
* Add casts to silence some warningsChris Robinson2011-05-021-2/+2
|
* Use a pointer-to-arrays for the local HRTF coefficientsChris Robinson2011-05-021-8/+8
|
* Implement HRTF mixers for multi-channel sourcesChris Robinson2011-05-021-12/+269
|
* Use flags instead of separate boolsChris Robinson2011-05-011-1/+1
|
* Add an HRTF filter for mono sourcesChris Robinson2011-05-011-2/+174
| | | | | | | | | | The data is based on the KEMAR HRTF data provided by MIT, which can be found at <http://sound.media.mit.edu/resources/KEMAR.html>. The compact measurements were used. See hrtf_tables.inc for more information. The filter is only available for stereo output, using a 44100hz playback rate. Note also that it currently only applies to mono sounds, and the cf_level and head_dampen config options are ignored while it is active.
* Fix looping on loop pointsChris Robinson2011-02-061-7/+12
|
* Avoid using a variable for array sizes and const variable initializationChris Robinson2011-01-231-5/+5
|
* Fix loop handling when traversing the buffer queue backwardsChris Robinson2011-01-231-3/+3
|
* Be consistent with variable name useChris Robinson2010-12-091-9/+9
|
* Combine stereo and multi-channel templatesChris Robinson2010-12-091-181/+13
|
* Use a matrix when rendering to the dry bufferChris Robinson2010-12-091-36/+37
|
* Use simple loops instead of several explicit lines for the mono mixerChris Robinson2010-12-091-24/+6
|
* Be a bit more generic with the multi-channel mixer loopsChris Robinson2010-12-091-77/+73
|
* Rename OUTPUTCHANNELS to something more descriptiveChris Robinson2010-12-011-9/+9
|
* Reorder some parameters for consistencyChris Robinson2010-11-291-1/+1
|
* Store double formats as floatChris Robinson2010-11-281-46/+0
| | | | | The mixer will cut it down to float anyway, so it's unnecessary and needlessly creates more mixer functions
* Rename some stuff for consistencyChris Robinson2010-11-281-3/+3
|
* Don't store the internal format in the bufferChris Robinson2010-11-281-1/+1
| | | | The type and channel config are good enough
* Support rear formats directly in the mixerChris Robinson2010-11-271-0/+23
|
* Support 64-bit double buffers directlyChris Robinson2010-11-271-0/+42
|
* Use enums when selecting the mixerChris Robinson2010-11-261-29/+34
|
* Avoid some more code duplicationChris Robinson2010-11-261-36/+44
|
* Properly clamp high pitch valuesChris Robinson2010-11-261-17/+0
|
* Subtract the fractional position separatelyChris Robinson2010-11-261-1/+2
|
* Rename some variables to be clearerChris Robinson2010-11-261-61/+62
|
* Make the buffer padding size dependent on the resamplerChris Robinson2010-11-261-15/+20
|
* Convert a few divisions to multiplicationsChris Robinson2010-11-261-6/+7
|
* Make a FRACTIONONE macro, and use itChris Robinson2010-11-261-8/+8
|
* Share the interpolation functions and use them in the reverb effectChris Robinson2010-11-261-23/+9
|
* Add a missing break statementChris Robinson2010-11-251-0/+1
|
* Add a cubic resamplerChris Robinson2010-11-251-6/+57
|
* Force the point resampler when the source plays at normal speedChris Robinson2010-11-251-1/+1
|
* Pass a pointer to the samplers so they can read just the samples they needChris Robinson2010-11-251-64/+51
|
* Add "pre-padding" to the temp bufferChris Robinson2010-11-251-10/+88
| | | | This will help to implement resamplers that want previous samples
* Make sure the target buffer size is frame alignedChris Robinson2010-11-251-0/+1
|
* Minor rework of the template macrosChris Robinson2010-11-251-47/+54
|
* Remove the cosine resamplerChris Robinson2010-11-251-44/+0
| | | | It's too slow when auxiliary sends are being used.
* Double-up the interpolation functions (and make them use doubles)Chris Robinson2010-11-251-65/+46
|
* Rename some "template" functionsChris Robinson2010-11-251-21/+21
|
* Always make sure there's a sample available to mix, for pending click removalChris Robinson2010-11-251-109/+53
|
* Use a temporary stack buffer to store the source buffer data to be mixedChris Robinson2010-11-251-72/+150
| | | | | | | | This makes it much easier to pack the playable buffer data so that it's a continuous data stream. This could normally be broken up otherwise, such as when using loop points or small queued buffers. Currently it defaults to a 16KB stack buffer, but this can be overridden at compile time.
* Use 0-based access for the buffer dataChris Robinson2010-11-241-10/+15
|
* Support 8-bit sample data in the mixerChris Robinson2010-11-241-1/+58
|
* Check the sample byte size after the resamplerChris Robinson2010-11-241-66/+51
|
* Get rid of a useless unionChris Robinson2010-11-241-12/+8
