Huong dan nay cat tan ca dieu do va giai thich, tung buoc, dung cach voice changer su dung virtual audio device, cach cai dat va cau hinh tren Windows 10 hoac 11, va dieu can lam khi co van de.
TL;DR
- Virtual audio device la trai audio chi chay tren phan mem xuat hien nhu microphone that su cho Windows va tat ca cac ung dung cua ban.
- Voice changer xu ly microphone that su cua ban, sau do xuat ra thiet bi ao de cac ung dung nghe thay giong noi da thay doi.
- VB-CABLE la trai audio ao WDM mien phi pho bien nhat cho cong viec nay.
- Ban phai chon trai ao trong moi ung dung (Discord, Zoom, OBS, v.v.).
- Mot so phan mem hien dai su dung low-latency audio capture injection de bo qua trai.
- Neu thiet bi khong xuat hien, hay khoi dong lai ung dung hoac dich vu Audio Windows.
Virtual Audio Device La Gi, Chinh Xac?
Virtual audio device la phan mem dang ky chinh no vao Windows la input hoac output audio - microphone hoac loa - ma khong co thiet bi vat ly phia sau. Doi voi he dieu hanh va tung ung dung chay tren no, thiet bi nay trong tuong tu voi usb headset that su hoac microphone condenser.
Trai tao ra thiet bi ao nay tuan theo dac ta WDM (Windows Driver Model) giong nhu phan cung audio that su su dung. WDM la khuon khom trai audio chuan ma Microsoft gioi thieu voi Windows 98 SE va da lam toi uu hoa tu do den nay. Vi no la khuon khom giong nhau, cac ung dung khong co cach phan biet thiet bi WDM ao voi thiet bi that - chinh vi vay thi teo nay hoat dong.
Khi voice changer dang chay, chuoi tin hieu trong nhu sau:
- Microphone vat ly cua ban ghi am giong noi cua ban.
- Phan mem voice changer nhan am thanh do, ap dung xu ly (pitch shift, voice clone, effect).
- Am thanh da xu ly duoc ghi vao buffer input cua thiet bi audio ao.
- Bat cu ung dung nao da chon thiet bi ao lam microphone cua no se doc tu buffer va nghe thay giong noi da xu ly.
Do chinh la toan bo khai niem. Moi thu - buoc cai dat, khac phuc su co, cai dat ung dung - chi la phuong dien thuc te cua viec lam cho chuoi nay hoat dong tin cay.
Tai Sao Voice Changer Can Virtual Audio Device
Microphone vat ly cua ban chi co the “so huu” mot pipeline audio tai mot thoi diem trong che do loai tru, va ngay ca trong che do chia se, no chi gui am thanh thom. Khong co co che san co nao trong Windows de bat tap am thanh tu microphone cua ban, thay doi no, va sau do trinh bay no nhu microphone khac cho cac ung dung khac.
Thiet bi audio ao giai quyet van de nay bang cach tao mot endpoint moi. Voice changer so huu microphone vat ly cua ban, thuc hien cong viec cua no, va ghi ket qua vao endpoint ao. Cac ung dung chi vao endpoint do va khong biet am thanh da duoc xu ly truoc do.
Ma khong co su tro gian nay, ban phai dinh tuyen am thanh qua loa vat ly cua ban va tro lai microphone cua ban - setup loopback gioi thieu echo, nhieu, va latency khong chap nhan duoc. Thiet bi ao giu tat ca dien tu va sach se.
Phan biet WDM va Low-Latency Audio Capture
Hai API audio quan trong o day:
WDM (Windows Driver Model) - lop trai level kernel. Thiet bi audio ao nhu VB-CABLE hoat dong o day. Ho cai dat trai ma Windows tai trong khi khoi dong va tung bao nhu thiet bi ton tai trong Sound Control Panel.
low-latency audio capture (Windows Audio Session API) - API cap cao hon ma cac ung dung su dung de noi chuyen voi cac thiet bi audio. Low-latency audio capture co the hoat dong trong che do chia se (nhieu ung dung chia se thiet bi) hoac che do loai tru (mot ung dung khoa thiet bi cho latency thap nhat).
Mot so cong cu moi hon, bao gom VoxBooster, su dung low-latency audio capture injection de dinh tuyen am thanh da xu ly ma khong can cai dat trai WDM. Phan mem bat tap phien audio o cap API. Dieu nay la li do VoxBooster duoc mo ta nhu khong co trai kernel - va li do no khong cam tay vao stack trai ma cac he thong anti-cheat nhu Easy Anti-Cheat hoac BattlEye theo doi.
Cach Cai Dat Trai Audio Ao WDM (VB-CABLE)
VB-CABLE boi VB-Audio Software la lua chon mien phi chuan de facto. Day la cach cai dat no sach se tren Windows 10 hoac 11.
Buoc 1: Tai Xung Trai
Tham quan vb-audio.com va tai VB-CABLE Driver Pack. File nay la kho luu tru zip chua co installer 32-bit va 64-bit. Ban khong can tra tien cho phien ban co ban - VB-Audio de xuat no la “donationware.”
Buoc 2: Chay Installer Nhu Quan Tri Vien
Giai nen zip. Nhan chuot phai VBCABLE_Setup_x64.exe (su dung phien ban 64-bit tren bat cu cai dat Windows hien dai nao) va chon Run as administrator. Nhan Install Driver. Windows se canh bao ban ve nha phat hanh khong xac minh - nhan Install de tiep tuc. Trai cai dat trong vay giay.
Buoc 3: Khoi Dong Lai May Tinh Cua Ban
Dieu nay khong tuy chon. Trai WDM duoc tai trong khi khoi dong. Bo qua khoi dong lai la nguyen nhan hang dau cua cac khieu nai “thiet bi ao khong xuat hien”. Khoi dong lai, sau do tiep tuc.
Buoc 4: Xac Minh Trong Sound Settings
Sau khi khoi dong lai, nhan chuot phai bieu tuong loa trong taskbar va mo Sound settings. Duoi Input, ban se thay CABLE Output (VB-Audio Virtual Cable). Cach dat ten co y dich gay nhom lom - “xuat” cua day cai la input microphone cho cac ung dung. Nghi ve no nhu dau xuat cua day ao.
Neu ban mo panel dieu khien Sound kieu cu (tim “Sound” trong menu Start - Sound - Recording tab), ban se thay CABLE Output duoc liet ke giua cac thiet bi ghi am cua ban.
Buoc 5: Dat Xuat Voice Changer Cua Ban
Mo voice changer cua ban va tim thiet lap output device hoac “virtual microphone output”. Chi tro vao CABLE Input (VB-Audio Virtual Cable). “Input” cua day cai la noi voice changer ghi am thanh. Am thanh do di ra dau day khac nhu CABLE Output, no se xuat hien trong cac ung dung nhu microphone.
Buoc 6: Chon Thiet Bi Ao Trong Moi Ung Dung
Bay gio hay dung vao tung ung dung ma ban muon su dung giong noi da thay doi:
- Discord: User Settings - Voice & Video - Input Device - CABLE Output
- Zoom: Settings - Audio - Microphone - CABLE Output
- OBS: Sources - Audio Input Capture - CABLE Output
- Teams: Settings - Devices - Microphone - CABLE Output
Ban phai lam dieu nay tren tung ung dung. Khong co phim tat “default microphone” toan he thong ghi de bat cai dat cap ung dung, meskipun ban co the dat CABLE Output lam thiet bi ghi am default Windows neu ban muon cac ung dung chon no tu dong khi khoi dong lan dau.
So Sanh Cac Trai Audio Ao Pho Bien
Cac voice changer khac nhau de nghi cac giai phap audio ao khac nhau. Deu day la phep so sanh nhanh:
