* | Use an ambisonics-based panning method | Chris Robinson | 2014-09-30 | 4 | -130/+134 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For mono sources, third-order ambisonics is utilized to generate panning gains. The general idea is that a panned mono sound can be encoded into b-format ambisonics as: w[i] = sample[i] * 0.7071; x[i] = sample[i] * dir[0]; y[i] = sample[i] * dir[1]; ... and subsequently rendered using: output[chan][i] = w[i] * w_coeffs[chan] + x[i] * x_coeffs[chan] + y[i] * y_coeffs[chan] + ...; By reordering the math, channel gains can be generated by doing: gain[chan] = 0.7071 * w_coeffs[chan] + dir[0] * x_coeffs[chan] + dir[1] * y_coeffs[chan] + ...; which then get applied as normal: output[chan][i] = sample[i] * gain[chan]; One of the reasons to use ambisonics for panning is that it provides arguably better reproduction for sounds emanating from between two speakers. As well, this makes it easier to pan in all 3 dimensions, with for instance a "3D7.1" or 8-channel cube speaker configuration by simply providing the necessary coefficients (this will need some work since some methods still use angle-based panpot, particularly multi-channel sources). Unfortunately, the math to reliably generate the coefficients for a given speaker configuration is too costly to do at run-time. They have to be pre- generated based on a pre-specified speaker arangement, which means the config options for tweaking speaker angles are no longer supportable. Eventually I hope to provide config options for custom coefficients, which can either be generated and written in manually, or via alsoft-config from user-specified speaker positions. The current default set of coefficients were generated using the MATLAB scripts (compatible with GNU Octave) from the excellent Ambisonic Decoder Toolbox, at https://bitbucket.org/ambidecodertoolbox/adt/ | ||||

* | Don't modify a capture device's format | Chris Robinson | 2014-09-08 | 1 | -168/+7 |
| | | | | | | OpenAL's capture API guarantees the application gets the format requested, or else the device will fail to open. The only valid change is that the capture buffer can be larger than requested. | ||||

* | Allow optional memory ordering to atomic methods | Chris Robinson | 2014-09-07 | 1 | -42/+81 |
| | | | | | Currently only C11 atomics make use of the memory order. If not specified, it defaults to almemory_order_seq_cst. | ||||
* | Check that atomic_load works with a const _Atomic | Chris Robinson | 2014-09-05 | 1 | -1/+1 |
| | | | | | | | The original C11 spec does not allow atomic_load to work on const _Atomic variables, which we sometimes do in alGet* methods, despite the fact that it does not modify the variable. An update to the C spec corrects this oversight, and GCC 4.9 has allowed it anyway, while Clang 3.4 does not. | ||||
