Converting MP1 to iPod-optimized audio encodes legacy MPEG Audio Layer 1 files for Apple's iconic portable music player. iPods never supported MP1 — the format was already legacy by the time the first iPod shipped in 2001. The iPod preset encodes to AAC at 128 kbps in an M4A container, matching the quality standard Apple established for its music ecosystem.
While iPods are discontinued, this preset serves users maintaining active iPod collections, particularly the iPod Classic's large-capacity hard drive that made it an ideal portable music library.
iPod users with MP1 audio from VCD collections or DAB recordings need conversion for playback. The iPod's Wolfson DAC was designed and tuned around AAC at 128-256 kbps, making the iPod preset the optimal encoding choice for this hardware.
For iPod Classic users with 160 GB storage, converting MP1 to efficient AAC maximizes the number of tracks that fit on the device while maintaining the quality standard Apple designed the hardware around.
FFmpeg decodes MP1 to PCM and encodes to AAC-LC at 128 kbps in an M4A container, matching iTunes' standard quality profile. iPod's dedicated audio decoder chip processes AAC with minimal battery impact. The M4A container carries metadata compatible with iPod's click-wheel navigation. iPod Classic supports up to 320 kbps AAC; iPod Shuffle up to 256 kbps.
At 128 kbps AAC, the iPod preset captures the full quality of most MP1 sources. Apple's engineers tuned iPod's audio hardware specifically for AAC at this bitrate — the output sounds excellent through the device's headphone jack with any standard headphones.
