Channel

Channel (Jalur Sinyal Audio)

Aliran sinyal audio individual dalam suatu rekaman atau file, di mana format mono memiliki satu channel dan format stereo memiliki dua channel (kiri dan kanan) untuk menciptakan kesan ruang dalam suara.

Detail Teknis

Konfigurasi channel audio: Mono (1 ch — berbicara, kompatibilitas), Stereo (2 ch — kiri/kanan, standar musik), Surround 5.1 (6 ch — L/R/C/LFE/Ls/Rs, film), 7.1 (8 ch), Atmos (berbasis objek, hingga 128 trek). Data PCM menyisipkan sampel per channel: [L₁R₁L₂R₂...] (interleaved) atau [L₁L₂...R₁R₂...] (planar). Ukuran file berskala linear dengan jumlah channel. Downmixing mengurangi channel (mis. stereo→mono: (L+R)/2, 5.1→stereo menggunakan koefisien: L'=L+0.707×C+0.707×Ls). Upmixing memerlukan teknik sintetis (duplikasi, HRTF, dekode matrix). Channel layout standar: WAV WAVEFORMATEXTENSIBLE, FLAC STREAMINFO, AAC PCE (Program Config Element).

Contoh

```
Audio channel configurations:

  Mono (1.0)     — 1 channel  — podcasts, phone calls
  Stereo (2.0)   — 2 channels — music, web audio
  Surround (5.1) — 6 channels — cinema, gaming
  Atmos (7.1.4)  — 12 channels — immersive audio

File size impact: stereo = 2× mono at same bitrate
  Podcast tip: mono 64 kbps ≈ stereo 128 kbps quality
