Convert 3G2 to AIFF — Free Online Converter

AIFF (Audio Interchange File Format) is Apple's uncompressed audio standard, storing raw PCM data at full CD quality or higher. Converting 3G2 to AIFF extracts the audio track from old CDMA phone recordings and decodes it to uncompressed PCM, producing a lossless representation suitable for professional editing in Logic Pro, GarageBand, or Pro Tools. The resulting files are significantly larger but contain every audio detail present in the original recording.

This conversion is particularly valuable when you need to process legacy phone audio in a professional digital audio workstation. Uncompressed AIFF eliminates codec overhead and allows sample-accurate editing, normalization, noise reduction, and mastering without any additional generation loss from codec re-encoding cycles.

Professional audio editors and DAWs work most reliably with uncompressed formats. While 3G2's AMR audio is already low-fidelity by modern standards, decoding it to AIFF gives you a clean, uncompressed baseline for applying noise reduction, equalization, and volume normalization without worrying about codec artifacts stacking on top of each other during re-encodes.

AIFF is also the preferred archival format in Apple-centric workflows. If you are preserving audio from legacy CDMA phone recordings — voicemails from a family member, historical voice notes, or field recordings — storing them as uncompressed AIFF ensures no further quality degradation over time and maximum compatibility with macOS audio tools for decades to come.
