Cara pakai

Untuk ceramah/kajian yang mau kecil tapi masih layak:

powershell -ExecutionPolicy Bypass -File .\convert-to-mp3.ps1 -InputFolder "D:\koleksi-audio" -OutputFolder "D:\hasil-mp3" -Mode speech

Untuk file sekecil mungkin:

powershell -ExecutionPolicy Bypass -File .\convert-to-mp3.ps1 -InputFolder "D:\koleksi-audio" -OutputFolder "D:\hasil-mp3" -Mode tiny

Untuk murottal/high quality:

powershell -ExecutionPolicy Bypass -File .\convert-to-mp3.ps1 -InputFolder "D:\koleksi-audio" -OutputFolder "D:\hasil-mp3" -Mode music

Kalau mau ambil audio dari video juga:

powershell -ExecutionPolicy Bypass -File .\convert-to-mp3.ps1 -InputFolder "D:\koleksi-media" -OutputFolder "D:\hasil-mp3" -Mode speech -IncludeVideo

-vn dipakai saat file video ikut diproses agar stream video dibuang dan hanya audio yang dikonversi ke MP3. gist.github

Arti mode

Mode	Setting	Cocok untuk
tiny	-q:a 9	Ukuran sekecil mungkin, kualitas paling ditekan. stackoverflow
speech	-q:a 7	Ceramah, voice note, kajian. stackoverflow
music	-q:a 4	Murotal atau audio yang ingin tetap enak didengar. stackoverflow

Catatan penting

Kalau target speaker MP3 lawas, beberapa perangkat kadang lebih cocok dengan CBR daripada VBR. Jadi kalau nanti ada file yang tidak terbaca normal, kita bisa ubah mode ke bitrate tetap seperti -b:a 128k atau -b:a 96k. Sumber Stack Overflow juga menekankan bahwa -b:a adalah CBR, sedangkan -q:a adalah VBR. stackoverflow
