This study proposes to manipulate participants' vocal cues, amplitude andfrequency, to change their dominance in a audio conference. We used paired comparisonto examine the effect of amplitude and frequency on dominance. The result showed thatparticipants perceived higher dominance while listening to ...
A frequency response is a visual representation of how well an audio component reproduces the audible range of sound. It’s usually presented as a line graph, with the device’s output amplitude on the y-axis (in decibels) plotted against frequency on the x-axis (in Hertz). A fixed ampl...
How does the Doppler effect affect amplitude?A Passing TrainMany people have noticed that when the engine of a train passes by the pitch of its horn suddenly changes. This is because of a phenomena called the Doppler Effect that explains the changes in waves emitted from a moving source....
Changing out a two-way speaker's 8 ohm bass driver with a 4 ohm will shift the low pass filter's crossover point lower a full octave which will feed the bass driver less mid freqs and create a "hole" in the speaker system's frequency response. The bass driver impedance mismatch won'...
changing the amplitude changes the effect of each specific noise on the audio you have recorded. Setting a tolerance of 0% will only affect any clipping that happens when the signal is at maximum amplitude. Setting a tolerance of 1% will, therefore, affect the clipping, which happens at 1% ...
The effect that will have on any transform is affect the levels of the higher frequency components of the signal - this is quite a normal EQ process. What your correspondent has suggested when she says "You should correct your signal after calcu...
Always set the sample rate to be at least twice as fast as the highest frequency observed. (Sometimes this is not possible because the highest frequency cannot be predicted.) Choose a DAQ system with a built-in anti-aliasing filter (AAF) system. Essentially this is a very steep low-pass ...
This creates a stream of pulses at the carrier frequency. Within each period of the carrier, the duty ratio of the PWM pulse is proportional to the amplitude of the audio signal. In the example of Figure 7, the audio input and triangular wave are both centered around 0 V, so that for...
Noise-canceling headsets have tiny microphones that monitor the sound of your surroundings and create their own sound wave with equal amplitude but inverted to the original wave, prompting them to eliminate external noise. Another option is directional microphones. Unlike omnichannel microphones that get...
Graphic equalizers enable adjustments across the frequency range, but they affect a range of frequencies around the target. On the other hand, parametric equalizers let you precisely boost or cut specific audio frequencies. Clear out distorted audio in Adobe Audition with EQ ...
