Convert 3G2 to WAV — Free Online Converter

WAV (Waveform Audio) is the standard uncompressed audio format on Windows and the most universally supported PCM audio container in existence. Converting 3G2 to WAV extracts the audio from old CDMA phone recordings and stores it as raw, uncompressed PCM data — the same format used by professional recording studios, audio forensics labs, and every digital audio workstation on every operating system.

WAV files contain audio samples exactly as they were decoded, with no compression whatsoever. For 3G2 phone recordings, this means the AMR audio is decoded to PCM and stored without any additional quality loss. While WAV files are larger than compressed formats, they are universally readable by every audio application ever created.

WAV is the lowest common denominator of audio formats — it works everywhere, always. No codec required, no format compatibility issues, no decoder bugs. If you need audio from 3G2 files to play on absolutely any system, WAV is the guaranteed-safe choice. Audio forensics tools, speech recognition engines, and scientific analysis software uniformly accept WAV input.

WAV is also the standard input format for audio editors like Audacity, Adobe Audition, Reaper, and Pro Tools on Windows. When you need to clean up, normalize, or restore audio from old phone recordings, WAV provides the uncompressed starting point that professional tools expect.
