AIFF (Audio Interchange File Format) is Apple's uncompressed audio format from 1988, storing PCM audio at full CD quality — 16-bit, 44.1 kHz, roughly 10 MB per minute. 3GP is a lightweight multimedia container built for 3G mobile networks, typically carrying AMR narrowband speech audio. Converting AIFF to 3GP compresses studio-quality audio down to mobile-friendly sizes, enabling delivery over constrained cellular connections to feature phones and legacy handsets.
AIFF files are enormous compared to what 3G-era mobile infrastructure can handle. A one-minute AIFF clip at CD quality is about 10 MB, while a one-minute AMR-NB file is under 100 KB. When you need to deliver voice content to legacy telecom systems — MMS gateways, voicemail servers, IVR platforms — 3GP with AMR encoding is the required format. Feature phones from Nokia, Samsung, and Sony Ericsson accept 3GP natively.
FFmpeg decodes the AIFF PCM stream, resamples from the source rate (typically 44.1 or 48 kHz) down to 8 kHz mono (AMR-NB) or 16 kHz mono (AMR-WB), and encodes using libopencore-amrnb or libopencore-amrwb. The resulting audio is muxed into a 3GP container. The compression ratio is extreme — a 10 MB AIFF minute becomes under 100 KB in AMR-NB, roughly a 100:1 reduction.
Significant quality loss is inherent. AIFF at 44.1 kHz captures frequencies up to 22 kHz; AMR-NB is limited to 300-3400 Hz (telephone bandwidth). Music will sound very degraded. Speech remains intelligible and natural-sounding, which is AMR's design target. AMR-WB expands the range to 50-7000 Hz and sounds noticeably better for voice.

AIFF to 3GP is a drastic downscale from studio quality to mobile telephony. Use it exclusively for speech content destined for cellular infrastructure, and always prefer AMR-WB when the receiving device supports it.
