MARK MDX 0408 FIR Filters Creation DSP 24 Bit Digital Audio Processor Tusi Lesona a le Tagata
FIR faamama ma talosaga
A faʻaaoga e le tagata faʻaoga le PEQ e faʻafetaui ai le leo leo ma seti se laina laina, e mafai ona ia mauaina le vaega o le faʻailoga ua suia, ona o le faamama IIR. Ae ui i lea, o oloa DSP e tuʻuina atu i le tagata faʻaoga se meafaigaluega aoga FIR faamama e faʻafetaui ai faʻailoga leo ma se laina laina.
O nisi fa'atatau:
Fuafuaga masani = Sampling/Taps
Avanoa min. fa'atelega ≈ Fuafuaga fa'atele*3
O lona uiga pe a fa'aoga fetuutuunai fa'ailo leo ma 48kHz, 1024 paipa, FIR filiga o le a aoga i taimi i luga ole 141Hz ole fa'alogo leo. E sili atu le maualuga o le tau o paipa, e sili atu le tifato o le fa'amama o le FIR.
FIR fa'amama le fa'aogaina o fa'ailoga leo o le a maua ai se fa'atuai fa'apitoa:
Fa'atuai = (1/Sampling Hz)*Tape/2
| Taps 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 |
- Linear o le vaega pi'o o le failauga;
- Faʻafetaui le vaega ma le tele o faʻataʻitaʻiga eseese failauga i totonu o le laina oloa e tasi, faʻapea foʻi ma faʻataʻitaʻiga eseese failauga i le faʻapipiʻiina o le poloketi e faʻafaigofie ai le debug o vaega failauga ma faʻasologa;
- Fegalegaleai ma faiga fa'asologa laina (mo le fa'avasegaina o le fa'alapotopotoga o le au maimoa);
- Fuafuaga vaeluaga o taimi e fa'aleleia atili ai le tumau o le tali fa'alava a le tele o vaeluaga failauga i luga o le latou fa'asalalauga Angle laina.
| Fua faaleotele leo | ×1 |  |
| Fa'alogo leo | ×1 |  |
| Windows PC (polokalame fa'apipi'i e aofia ai le Smarts, re Phase po'o le FIR Designer, Mconsole) | ×1 |  |
| FIR fa'alogo leo po'o le DSP mana feso'otaiga ampola | ×1 |   |
| Fofoga Fetalai | ×1 |  |
Fa'asologa fa'asologa o feso'ota'iga:
Fa'aaogā polokalame fa'apitoa e fa'atulaga ai le tele ma le vaega o le FIR
Laasaga 1: fua vaega pi'o o le failauga ile Smaart V7
Laasaga 2: kopi le pupuni ile ASCII ile Smaart V7
Laasaga 3: kopi le pupuni ile polokalame rePhase
“Fa'aulufaleina Fua Mai le Laupapa”
Laasaga 4: fetu'una'i vaega EQ po'o so'o se isi fa'amaufa'ailoga i polokalama fa'akomepiuta, e fetaui ma se laina laina mo le failauga
Laasaga 5: auina atu i fafo .txt file ina ua uma ona faatulagaina
Fa'ailoga:
- Seti tap i le 2048/1024/768/512/256, o lea ua matou seti i le 512.
- Seti fua ile 48000Hz.
- E mafai e le tagata fa'aoga ona toe fa'aigoa lenei file ma maua gofie.
- Seti le lisi mo le auina atu i fafo file, pei ole C:/Users/User/Desktop.
- Kiliki "faia" e auina atu i fafo se FIR .txt file.
Laasaga 6: faaulufale mai FIR .txt file i le FIR leo faʻalogo poʻo le DSP mana fesoʻotaʻiga ampola
Tatala le polokalama Mconsole, e mafai e le tagata faʻaoga ona filifili se auala faʻapipiʻi poʻo se auala faʻapipiʻi pe a manaʻomia, e pei o le FIR i le auala faʻapipiʻi, o le a faʻaalia ai se faamalama galuega FIR.
lolomi IMPORT e fa'aulufale mai ai le txt. file, nai lo le lolomi STORE e fa'atino ai lenei fa'aulufale mai
manatua e faaleaogaina le BIPASS.
Laasaga 8: toe fuaina le pi'o o le failauga, fa'aaoga e mafai ona maua ai le fa'asili atu.
A mae'a fa'atulagaina uma, faamolemole ia manatua e teu se seti mo lou galue malosi i le failauga.
