* EFX: Add 3D processing for autowahRaulshc2018-07-251-36/+55
| | | Add 3D processing code. It can be activated at compilation time.
* EFX: Autowah implementationRaulshc2018-07-252-2/+271
| | | Add autowah effect using biquad peaking filter and envelope follower
* Limit the normalized filter frequency to under halfChris Robinson2018-07-211-1/+1
| | | | | Nearing half, weird things can start happening with the filters' generated sine and cosine values.
* Improve handling of 0hz ring modulator frequencyChris Robinson2018-07-211-5/+13
|
* Start an extension to allow source filter gains greater than 1Chris Robinson2018-07-151-0/+1
|
* Prefer sndio over OSS when both are enabledTobias Kortkamp2018-06-221-3/+3
| | | | Signed-off-by: Tobias Kortkamp <[email protected]>
* Properly get the full executable and pathname on FreeBSDChris Robinson2018-06-081-4/+4
|
* Always prepare the ALSA PCM handle before starting captureChris Robinson2018-06-081-2/+9
| | | | | | Draining the ALSA device via stopping puts it into a setup state, which requires re-preparing before playback can start again. Preparing it prior to the first start seems to cause no harm, so just always do it before starting.
* Stop capture devices while closingkdhp2018-06-081-0/+6
| | | | | | | In 'alcCaptureCloseDevice', check if the capture device is running and stop it if necessary. This fixes the case where the device data is deallocated while a background thread is still running (Issue #199)
* Clamp the maximum normalized reference frequency tooChris Robinson2018-06-031-1/+1
|
* Use a higher normalized frequency limit for the ring modulatorChris Robinson2018-06-021-1/+1

|
* Slightly simplify the modulator square wave generatorChris Robinson2018-05-311-3/+3
|
* EFX: Ring modulator fixesRaulshc2018-05-311-3/+3
| | | Change from unipolar to bipolar carrier signal in the Ring modulator effect.
* Avoid extra sample copies and storage in the modulator effectChris Robinson2018-05-291-7/+6
|
* Use fastf2i instead of manual rounding in another placeChris Robinson2018-05-291-1/+2

* Merge pull request #193 from Raulshc/Frequency-shifterkcat2018-05-222-1/+328
|\ | | | | EFX: Frequency shifter
| * EFX: Frequency Shifter implementationRaulshc2018-05-202-1/+328
| | | | | | Add frequency shifter effect using discrete Hilbert transform. Only mono signal processing by now (LEFT_DIRECTION).
* | Add a method to queue multiple buffer layers onto a sourceChris Robinson2018-05-211-0/+8
| |
* | Further clarify a comment about float precisionChris Robinson2018-05-211-3/+3
| |
* | Simplify counting for the bsinc FIR loopChris Robinson2018-05-192-8/+16
| |
* | Accumulate ambisonic upsampler gains using double-precisionChris Robinson2018-05-181-4/+4
|/
* Add a function to calculate coefficients from X, Y, Z componentsChris Robinson2018-05-171-6/+3
|
* Simplify counting for SIMD MixRow functionsChris Robinson2018-05-152-16/+20

* Undefine the correct macrosChris Robinson2018-05-151-2/+2
|
* Move the ALcomplex and FFT functions to a separate fileChris Robinson2018-05-151-99/+8
|
* Avoid using unsigned values for signedChris Robinson2018-05-151-1/+1
|
* Use a step counter for gain steppingChris Robinson2018-05-144-76/+100
| | | | | This should provide more stable stepping, preventing floating-point errors from accumulating on each step/sample.
* Add a faster double-to-int converter for x87 buildsChris Robinson2018-05-141-1/+25
|
* Use more accurate elevations for virtual HRTF speaker positionsChris Robinson2018-05-141-8/+8
|
* Use fastf2i instead of manually rounding with float2intChris Robinson2018-05-121-4/+4
|
* Add and use a method for fast float roundingChris Robinson2018-05-122-1/+2
| | | | | Unlike fastf2i, this keeps the result as a float instead of converting to integer.
* Simplify calculating the HRTF B-Format IR lengthChris Robinson2018-05-041-19/+19
|
* Don't assume the FPU is round-to-zero in the pitch shifterChris Robinson2018-05-041-21/+3
