The AcxCircuitStopIoWithTag function is used to signal to the operating system to temporarily stop circuit I/O. AcxCircuitTemplateCreate The AcxCircuitTemplateCreate function is used to create a circuit template for use by the audio class extension (ACX) manager. AcxCompositeTemplateAssignCircuits ...
I created a sample project that uses theEZOutputto act as a signal generator to play sine, square, triangle, sawtooth, and noise waveforms.Here's a snippet of code to generate a sine tone: ...doubleconstSAMPLE_RATE =44100.0; - (void)awakeFromNib ...
head, or move your iPad, iPhone, etc, that the audio still feels like it's coming directly from the device instead of staying constant relative to your own face's front-and-center is done using both psycho-acoustics and more straightforward inverse gyro compensation in the signal as a ...
A digital audio signal is encoded as a string of ones and zeroes. There are different conventions as to how this encoding should take place, and they are mostly incompatible with each other. There are also different ways in which a given string of ones and zeroes can be represented physicall...
R6 is adjusted using a potentiometer in Fig. 6 to obtain different values of parameter d. When d = 10, then R6 = 10kΩ, the phase transition trajectory of hyperchaotic signal is exhibited by an oscilloscope which is shown in Fig. 7a; When d = 17, the R6 = 5.88k...
if time signal are padded twice longer, frequency bases are twice denser. denser bases yield a smoother curve for frequency spectrum. Make sure you grasp these two concepts 100% before moving on.They'll come in handy soon enough. Naive implementation of DFT (strictly by definition) is of O...
