MARK MDX 0408 FIR Filters Creation DSP 24 Bit Digital Audio Processor Manual
Fir filter le lisebelisoa
Ha mosebelisi a sebelisa PEQ ho lokisa lets'oao la molumo le ho beha boholo ba mohala, a ka fumana karolo ea lets'oao e fetotsoe, ka lebaka la sefahla sa IIR. Leha ho le joalo, lihlahisoa tsa DSP li fa mosebelisi sesebelisoa se sebetsang sa FIR ho fetola lets'oao la molumo ka karolo e lekanang.
Palo e itseng:
Qeto ea khafetsa = Sampling/ Ho tlanya
E fumaneha ka mets. maqhubu ≈ Qeto ea maqhubu*3
E bolela ha o sebelisa lets'oao la molumo ka 48kHz, lipompo tsa 1024, li-filters tsa FIR li tla sebetsa khafetsa ka holimo ho 141Hz ea lets'oao la molumo. Lipompo li na le boleng bo phahameng ho feta, filthara ea FIR e kobeha moepa ho feta.
Lets'oao la audio la FIR filthara le tla hlahisa tieho e itseng:
tieho = (1/Sampling Hz)*Taps/2
| Tlanya Sampling | 48kHz | 96kHz |
| 256 | 2.67ms, LF 563Hz | 1.33ms, LF 1125Hz |
| 512 | 5.33ms, LF 279Hz | 2.67ms, LF 558Hz |
| 768 | 7.99ms, LF 188Hz | 4.00ms, LF 375Hz |
| 1024 | 10.67ms, LF 141Hz | 5.33ms, LF 281Hz |
| 2048 | 21.33ms, LF 70Hz | 10.67ms, LF 141Hz |
- Mothalo oa lekhalo la mokhahlelo oa sebui;
- Bapisa mohato le boholo ba mefuta e fapaneng ea libui ka har'a mohala o tšoanang oa sehlahisoa, hammoho le mefuta e fapaneng ea libui morerong oa ho kenya ho etsa hore ho be bonolo ho lokisa lihlopha le lihlopha tsa libui;
- Ho sebetsana le litsamaiso tsa linear array (bakeng sa ntlafatso ea sebaka sa bamameli);
- Ntlafatso ea karohano ea khafetsa ho ntlafatsa botsitso ba karabelo ea khafetsa ea libui tsa likarohano tse ngata ho feta li-Angle range tsa tsona.
| Maekerofounu ea ho lekanya | ×1 |  |
| Audio Interface | ×1 |  |
| Windows PC (software e kentsoeng ho kenyeletsoa Smarts, re Phase kapa FIR Designer, Mconsole) | ×1 |  |
| FIR audio processor kapa matla a marang-rang a DSP ampmoqhobi | ×1 |   |
| Sebui | ×1 |  |
Setšoantšo sa moralo oa khokahano:
Ho sebelisa software ea motho oa boraro ho beha boholo ba FIR le karolo
Mohato oa 1: lekanya lekhalo la sebui ka Smaart V7
Mohato oa 2: kopitsa curve ho ASCII ho Smaart V7
Mohato oa 3: kopitsa curve ho software rePhase
"Litekanyo tsa ho Kenya ho tsoa ho Clipboard"
Mohato oa 4: lokisa phase EQ kapa paramethara efe kapa efe ho software, ho tsamaisana le karolo ea mola bakeng sa sebui
Mohato oa 5: thomello .txt file ka mora ho beha
Matšoao:
- Beha lipompo ho 2048/1024/768/512/256, mona re beha 512.
- Beha sekhahla ho 48000Hz.
- Mosebedisi a ka reha sena hape file 'me u fumane habonolo.
- Beha bukana bakeng sa ho romelloa kantle file, joalo ka C:/Users/User/Desktop.
- Tobetsa "hlahisa" ho romela FIR .txt file.
Mohato oa 6: import FIR .txt file ho processor ea audio ea FIR kapa matla a marang-rang a DSP ampmoqhobi
Bula software ea Mconsole, mosebelisi a ka khetha mocha oa ho kenya kapa mocha oa tlhahiso ha ho hlokahala, joalo ka FIR ka kanaleng ea tlhahiso, e tla bonts'a fensetere ea ts'ebetso ea FIR.
tobetsa IMPORT ho kenya txt. file, ho feta ho tobetsa STORE ho kenya tšebetsong thomello ena
hopola ho hlakola BYPASS.
Mohato oa 8: lekanya mothinyeho oa sebui hape, tšebeliso e ka e fumana e fetoha mola o ho feta.
Ka mor'a litlhophiso tsohle, ka kopo hopola ho boloka li-preset bakeng sa ho sebetsa ha hao ka thata ho sebui.
