Isihluzo esivakalayo sixhomekeke rhoqo amplifier isekethe, ukusebenza kuluhlu lwamaza omsindo, i-0 Hz ukuya ngaphaya kwe-20 kHz.
Iintlobo ezininzi zezihluzi zikhona kwizicelo eziquka izilinganisi zegraphic, izinto zokudibanisa, iziphumo zomsindo, abadlali beCD kunye neenkqubo zokwenyani zokwenyani.
Ukuba sisandisi-lizwi esixhomekeke kumaza, ngokolona hlobo lwaso olusisiseko, isihluzi se-audio siyilelwe ukukhulisa, ukudlula okanye ukunciphisa (i-negative amplification) ezinye iindidi zamaza.
Iindidi eziqhelekileyo zibandakanya izihluzi ezidlulayo ezisezantsi, ezidlula kwiifrikhwensi ezingaphantsi kweefrikhwensi zazo zokuqhawula, kwaye ngokuthe ngcembe zithomalalisa iifrikhwensi ngaphezulu kwe-cutoff frequency.
Isihluzi se-high-pass senza okuchaseneyo, sigqitha iifrikhwensi eziphezulu ngaphezulu kwe-cutoff frequency, kwaye ngokuthe ngcembe sithomalalisa amaza ngezantsi kwe-cutoff frequency.
Isihluzo se-bandpass sidlula iifrikhwensi phakathi kwefrikhwensi yaso emibini yokuphuma, ngelixa sicutha abo bangaphandle koluhlu.
Isihluzi esale ibhendi, sinciphisa iifrikhwensi phakathi kweefrikhwensi ezimbini zokuqhawula, ngelixa sigqitha ezo zingaphandle koluhlu 'lwala'.
Isihluzi sokudlula zonke, sigqithisa zonke iifrikhwensi, kodwa sichaphazela isigaba salo naliphi na icandelo le-sinusoidal elinikiweyo ngokuphindaphindiweyo.
Kwezinye izicelo, ezinje ngoyilo lwezilinganisi zegraphic okanye izidlali zeCD, izihluzi ziyilwa ngokweseti yeenqobo zokukhetha ezinje ngebhendi yokupasa, ukuthomalalisa ibhendi, ibhendi yokumisa, kunye nokuyeka ibhendi yokuthomalalisa, apho iibhendi zokupasa ziyi-attenuation. Uluhlu lwefrikhwensi apho i-audio ithotywe ngaphantsi kobuninzi obuchaziweyo, kwaye iibhanti zokumisa ziziintlobo zamafrikhwensi apho i-audio kufuneka icuthwe ngobuncinci obuchaziweyo.
Kwiimeko ezinzima ngakumbi, isihluzo se-audio sinokunika i-loop yempendulo, eyazisa i-resonance (i-ringing) ecaleni kokunciphisa.
Izihluzi zeAudio nazo zinokuyilwa ukunika inzuzo (ukunyusa) kunye nokuthomalalisa. Kwezinye ii-aplikeshini, ezinje ngee-synthesizers okanye isandi, ubuhle besihluzo kufuneka sivavanywe ngokuzimeleyo.
Izihluzi ze-audio zinokuphunyezwa kwiisekethe ze-analog njengezihluzo ze-analog okanye kwikhowudi ye-DSP okanye isofthiwe yekhompyutha njengezihluzo zedijithali.
Ngokubanzi, igama elithi 'isihluzi somsindo' linokusetyenziswa ukubhekisela kuyo nantoni na etshintsha i-timbre, okanye umxholo we-harmonic we- isiginali yomsindo.
NdinguJoost Nusselder, umseki weNeaera kunye nomthengisi womxholo, utata, kwaye ndiyakuthanda ukuzama izixhobo ezitsha ngesiginkci entliziyweni yothando lwam, kunye neqela lam, ndisenza amanqaku eblogi anzulu ukusukela ngo-2020. ukunceda abafundi abathembekileyo ngokurekhoda kunye neengcebiso zesiginci.
