MPG files carry MPEG-1/MPEG-2 video with MP2 audio from DVDs, Video CDs, and broadcast recordings, while AMR (Adaptive Multi-Rate) is a narrowband speech codec operating at 4.75-12.2 kbps with 8 kHz sampling — the standard voice codec for GSM cellular networks. Converting MPG to AMR extracts the audio, downsamples it drastically, and encodes it exclusively for voice-quality speech delivery on cellular devices.
AMR exists for one purpose: transmitting voice over cellular networks at the lowest possible bitrate. If you need to extract speech (dialogue, narration, commentary) from MPG recordings and deliver it via MMS, embed it in telephony systems, or store it on devices with extreme storage limitations, AMR provides functional voice quality at approximately 1 KB per second.
FFmpeg decodes the MP2 audio from the MPG container, downsamples from the original rate (typically 44.1 or 48 kHz) to 8 kHz mono, and encodes using libopencore_amrnb. The output is a raw AMR file with the standard #!AMR file header. The codec operates at adaptive bitrates between 4.75 and 12.2 kbps, optimized for frequencies between 300 and 3400 Hz — the human voice range.
AMR audio sounds like a phone call. Music, environmental sounds, and anything outside the 300-3400 Hz voice band will be severely degraded or eliminated. At 12.2 kbps, speech is clear and intelligible. Below 7.4 kbps, robotic artifacts become noticeable. The quality drop from DVD-quality MP2 to AMR is extreme.

MPG to AMR conversion serves the narrow niche of voice extraction for cellular and telephony applications. The extreme compression is only justified when speech intelligibility at minimal bandwidth is the sole requirement.
