Convert ALAC to iPod Audio — Free Online Converter

ALAC is Apple's lossless audio codec, supported on iPod Touch but requiring software decoding that impacts battery life on older iPod models. iPod Audio produces AAC in M4A — the codec Apple optimized iPod hardware around. The iPod Classic's Wolfson WM8758 and Cirrus Logic CS42L55 DACs include dedicated AAC hardware decoders enabling 30+ hours of continuous AAC playback versus significantly less with software-decoded ALAC.

Converting ALAC to iPod-optimized AAC creates compact, battery-efficient music files from lossless Apple sources. The perfect PCM from ALAC decoding ensures the AAC output achieves maximum quality for the target bitrate.

iPod Classic (the most popular iPod for large music libraries) decodes AAC in hardware but ALAC in software. AAC playback on iPod Classic delivers 30-40 hours battery life; ALAC reduces this to approximately 20 hours. Converting ALAC to AAC extends listening time by 50% or more.

iPod storage is also finite. A 160 GB iPod Classic holding ALAC stores roughly 15,000 songs; the same device with 256 kbps AAC holds 40,000+ songs. For users with large lossless collections, AAC conversion dramatically increases library capacity.
