| * Configure CMake to require available backends on CI servicesMarcel Metz2017-03-062-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Configure CMake to require the installed backend libraries. This should help to find build system regressions. On TravisCI with Linux this requires the ALSA, PulseAudio, PortAudio, OSS and JACK backend. On TravisCI with Android cross compile Linux this requires the OpenSL backend. On TravisCI with MacOSX this requires the CoreAudio backend. ON AppVeyor with Windows this requires the WinMM, DSound and MMDevAPI backend.

* | Start a ALC_SOFT_loopback2 extensionChris Robinson2017-02-282-55/+218
|/ | | | | | | | | | | | | | | | | | | | | | This extends the base ALC_SOFT_loopback extension with support for B-Format. When ALC_FORMAT_CHANNELS_SOFT is set to ALC_BFORMAT3D_SOFT, then additional attributes must be specified. ALC_AMBISONIC_LAYOUT_SOFT must be set to ALC_ACN_SOFT or ALC_FUMA_SOFT for the desired channel layout, ALC_AMBISONIC_SCALING_SOFT must be set to ALC_N3D_SOFT, ALC_SN3D_SOFT, or ALC_FUMA_SOFT for the desired channel scaling/normalization scheme, and ALC_AMBISONIC_ORDER_SOFT must be set to an integer value greater than 0 for the ambisonic order (maximum allowed is implementation-dependent). Note that the number of channels required for ALC_BFORMAT3D_SOFT is dependent on the ambisonic order. The number of channels can be calculated by: num_channels = (order+1) * (order+1); /* or pow(order+1, 2); */ In addition, a new alcIsAmbisonicFormatSupportedSOFT function allows apps to determine which layout/scaling/order combinations are supported by the loopback device. For example, alcIsAmbisonicFormatSupported(device, ALC_ACN_SOFT, ALC_SN3D_SOFT, 2) will check if 2nd order AmbiX (ACN layout and SN3D scaling) rendering is supported for ALC_BFORMAT3D_SOFT output.

|
* Move the current buffer queue entry and play position to the voiceChris Robinson2017-02-275-127/+137
| | | | | | | | | | | | | | This has a couple behavioral changes. First and biggest is that querying AL_BUFFERS_PROCESSED from a source will always return all buffers processed when in an AL_STOPPED state. Previously all buffers would be set as processed when first becoming stopped, but newly queued buffers would *not* be indicated as processed. That old behavior was not compliant with the spec, which unequivocally states "On a source in the AL_STOPPED state, all buffers are processed." Secondly, querying AL_BUFFER on an AL_STREAMING source will now always return 0. Previously it would return the current "active" buffer in the queue, but there's no basis for that in the spec.
* Ensure a non-playing or -paused source does not use a mixing voiceChris Robinson2017-02-254-46/+62

* Set CMP0020 for QtChris Robinson2017-02-251-0/+3
|
* Improve handling of source state readsChris Robinson2017-02-242-72/+89
| | | | | | | This avoids using seq_cst for loading the source state when either inside the mixer, or otherwise protected from inconsistencies with async updates. It also fixes potential race conditions with getting the source offset just as a source stops.

* Alter how panpot/pair-wise panning worksChris Robinson2017-02-233-32/+32
| | | | | | | | | | | | | | | | | | | This change allows pair-wise panning to mostly go through the normal ambisonic panning methods, with one special-case. First, a term is added to the stereo decoder matrix's X coefficient so that a centered sound is reduced by -3dB on each output channel. Panning in front creates a similar gain response to the typical L = sqrt(1-pan) R = sqrt(pan) for pan = [0,1]. Panning behind the listener can reduce (up to) an additional -10dB, creating a audible difference between front and back sounds as if simulating head obstruction. Secondly, as a special-case, the source positions are warped when calculating the ambisonic coefficients so that full left panning is reached at -30 degrees and full right at +30 degrees. This is to retain the expected 60-degree stereo width. This warping does not apply to B-Format buffer input, although it otherwise has the same gain responses.
* Rename stereo-panning option to stereo-encodingChris Robinson2017-02-225-37/+40
| | | | Also rename the 'paired' value to 'panpot', and make it the default.

* Reduce the default period count to 3Chris Robinson2017-02-223-3/+3
|
* Don't remove a period from the OSS bufferChris Robinson2017-02-221-11/+4
| | | | | Since we're now waiting for space to be available before mixing, the mixing buffer isn't adding another period.
