XRReferenceSpace.getOffsetReferenceSpace() - Web APIs
this is demonstrated in the example implementing rotation based on non-xr inputs, which demonstrates a way to use this method to let the user use their mouse to pitch and yaw their viewing angle.

AudioListener - Web APIs
deprecated features audiolistener.dopplerfactor a double value representing the amount of pitch shift to use when rendering a doppler effect.
... in a previous version of the specification, the dopplerfactor and speedofsound properties and the setposition() method could be used to control the doppler effect applied to audiobuffersourcenodes connected downstream — these would be pitched up and down according to the relative speed of the pannernode and the audiolistener.
... these features had a number of problems: only audiobuffersourcenodes were pitched up or down, not other source nodes.
... because the velocity of the panner and the listener were not audioparams, the pitch modification could not be smoothly applied, resulting in audio glitches.

XRView - Web APIs
the createteleporttransform() function returns the transform needed to move and rotate an object whose current situation is described by the reference space refspace to a new position and orientation which is computed using previously recorded mouse and keyboard input data which has generated offsets for yaw, pitch, and position along all three axes.
... function applymousemovement(refspace) { if (!mouseyaw && !mousepitch && !axialdistance && !transversedistance && !verticaldistance) { return refspace; } // compute the quaternion used to rotate the image based // on the pitch and yaw.
... quat.identity(inverseorientation); quat.rotatex(inverseorientation, inverseorientation, -mousepitch); quat.rotatey(inverseorientation, inverseorientation, -mouseyaw); // compute the true "up" vector for our object.
...this represents the rotation of the object given the values of mousepitch (rotation around the object's reference's space's x axis) and mouseyaw (rotation around the object's y axis).

HTMLMediaElement - Web APIs
htmlmediaelement.preservespitch is a boolean that determines if the pitch of the sound will be preserved.
... if set to false, the pitch will adjust to the speed of the audio.
... this is implemented with prefixes in firefox (mozpreservespitch) and webkit (webkitpreservespitch).

Viewpoints and viewers: Simulating cameras in WebXR - Web APIs
tilting (pitching up or down) when you tilt or pitch the camera, you keep it fixed in space at the same coordinates while changing the direction in which it's facing vertically without altering the horizontal portion of its facing at all.
...to perform the rotations separately, you use euler angles (separate angles around each axis) to apply pitch, yaw, and roll like this: mat4.rotatex(viewmatrix, viewmatrix, pitchangle); mat4.rotatey(viewmatrix, viewmatrix, yawangle); mat4.rotatez(viewmatrix, viewmatrix, rollangle); you can instead construct a quaternion representing a combined rotation axis from the euler angles, then rotate the matrix using multiplication, like this: const axisquat = quat.create(); const rotatematrix = mat4.create()...
...; quat.fromeuler(axisquat, pitchangle, yawangle, rollangle); mat4.fromquat(rotatematrix, axisquat); mat4.multiply(viewmatrix, viewmatrix, rotatematrix); this converts the euler angles for pitch, yaw, and roll into a quaternion representing all three rotations.

Digital audio concepts - Web media technologies
the shorter the wavelength (the closer together the crests of the wave are), the higher the frequency (or pitch) of the sound that's produced.
...since the range of human hearing is from around 20 hz to 20,000 hz, reproducing the highest-pitched sounds people can generally hear requires a sample rate of more than 40,000 hz.
...you can even adjust the audio bandwidth to factor in the pitch of the individual speaker's voice.
