Ringing can affect audio equipment in a number of ways. Audio amplifiers can produce ringing depending on their design, although the transients that can produce such ringing rarely occur in audio signals. Transducers (i.e., microphones and loudspeakers) can also ring. Mechanical ringing is more of a problem with loudspeakers as the moving ...
On the other hand, if the cause is a band-limited signal, as in JPEG, one cannot simply replace a filter, and ringing artifacts may prove hard to fix – they are present in JPEG 2000 and many audio compression codecs (in the form of pre-echo), as discussed in the examples.
Amazon Alexa, or, Alexa, [2] is a virtual assistant technology largely based on a Polish speech synthesizer named Ivona, bought by Amazon in 2013. [3] [4] It was first used in the Amazon Echo smart speaker and the Amazon Echo Dot, Echo Studio and Amazon Tap speakers developed by Amazon Lab126.
Amazon announced new AI capabilities for its Alexa products last week, based on a model it’s calling AlexaLLM (LLM refers to the “large language model”). The technology will make Alexa ...
The Echo Input is an Alexa input device with no on-board speakers. [93] It must be connected to external speakers for audio output. The Echo Link is a higher-end version of the Echo Input, with additional output ports and a volume knob. [94] The Echo Link Amp has the same controls of the Link, but with an amplifier.
The torsional deflection of a simple cylinder cannot radiate efficiently acoustic noise, but with particular boundary conditions the stator can radiate acoustic noise under torque ripple excitation. [8] Structure-borne noise can also be generated by torque ripple when rotor shaft line vibrations propagate to the frame [9] and shaft line.
Amazon Echo devices have Sidewalk enabled by default and do not inform their owner about it. The feature can be disabled via the official app. [10] A number of prominent news publishers, including The Guardian, [13] ArsTechnica, [11] CNET, [14] PCMag, [15] Click2Houston, [16] and Bleeping Computer, [17] expressed concern with opt-out nature of the network and published guides how to disable ...
In audio systems, parasitic oscillations can sometimes be heard as annoying sounds in the speakers or earphones. The oscillations waste power and may cause undesirable heating. For example, an audio power amplifier that goes into parasitic oscillation may generate enough power to damage connected speakers. A circuit that is oscillating will not ...
