Perbandingan Keunggulan

AAC Keunggulan

Better quality than MP3 at equal bitrate — the industry standard since 2000s.
Universally supported on every smartphone, OS, and browser.
Efficient on battery thanks to widespread hardware decoding.
Scales from 8 kbps speech (HE-AACv2) to lossy-transparent 320 kbps.
Five-channel + LFE surround support out of the box.

WMA Keunggulan

Good quality at low bitrates (32-64 kbps) — outperformed MP3 in that range.
Native playback on every Windows version 2000 through 10.
Lossless variant available (WMA Lossless) for archiving.
Supports multichannel 5.1 surround audio.

Keterbatasan

AAC Keterbatasan

Patent-encumbered — encoders have licensing fees, which is why open alternatives (Opus, Vorbis) exist.
Slightly more complex to encode than MP3.
Raw .aac streams carry no seek index — tooling often prefers M4A/MP4 containers.
Lossy — not suitable for archival or studio production.

WMA Keterbatasan

Proprietary — poor support outside Windows and Windows Media Player.
DRM variants made files brittle — many purchased tracks became unplayable when stores shut down.
Ecosystem abandoned — no modern editors, hardware decoders, or streaming services use WMA.
Windows 11 deprecated Windows Media Player entirely.
