Apple Lossless Audio Codec (ALAC) compresses audio without losing any data, similar to how a ZIP file compresses documents. For owners of old 3GA voice recordings from Samsung Galaxy, LG Optimus, or other 3G-era Android phones, converting to ALAC creates a space-efficient lossless archive that integrates perfectly with the Apple ecosystem. ALAC files play natively in Apple Music, iTunes, QuickTime, and every Apple device from the original iPod Classic onward without any third-party software.
The 3GA format stores voice recordings in the AMR codec, which is a lossy narrowband format designed for GSM and UMTS telephony. Converting to ALAC preserves the decoded AMR audio in a lossless container, ensuring no further quality degradation occurs during storage or future format conversions. While the original AMR quality is modest (telephony-grade speech captured on feature phones), ALAC guarantees that what remains is preserved perfectly for future use, editing, or transcription.
ALAC sits at the intersection of lossless quality and Apple ecosystem convenience. Unlike FLAC, which requires third-party apps on iOS devices, ALAC is supported out of the box on every Mac, iPhone, iPad, iPod, and Apple TV. If your personal media library lives in Apple Music or iTunes, ALAC is the only lossless option that syncs seamlessly to all your devices via iCloud Music Library without any transcoding.
For archival purposes, ALAC makes more sense than uncompressed AIFF or WAV because it typically achieves 40-60% compression while preserving identical audio data. A collection of hundreds of old phone recordings from Nokia, Samsung, and Ericsson handsets takes significantly less storage space in ALAC format. And unlike lossy formats like AAC or MP3, you can always convert ALAC to any other format in the future without any generational quality loss — the decoded audio is mathematically identical to the original conversion output.
FFmpeg decodes the AMR-NB (8 kHz) or AMR-WB (16 kHz) audio from the 3GA container and re-encodes it using the ALAC codec into an M4A container (MPEG-4 Part 14 with .m4a extension). The output uses 16-bit depth at 44.1 kHz sample rate. ALAC compression is lossless — the decoded PCM data is bit-for-bit identical to the uncompressed intermediate representation. Typical compression ratio for speech content is around 50-60% of the equivalent uncompressed size due to the low entropy of narrowband voice audio.
ALAC is mathematically lossless — the decoded audio is identical to the PCM signal produced by decoding the original AMR source. However, the quality of that PCM signal is limited by what the AMR codec captured on the original handset. AMR-NB records speech at 8 kHz with a 300-3400 Hz bandwidth, so the ALAC output faithfully preserves this telephony-grade audio without adding any further artifacts. The advantage over lossy alternatives like AAC or MP3 is that ALAC introduces zero additional quality loss during encoding.

Converting 3GA to ALAC gives you the best of both worlds: lossless audio preservation with native Apple device compatibility. It is the ideal format for anyone who uses Apple devices and wants to ensure their old mobile recordings from the 3G era are stored at the highest possible fidelity.
