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.
FFmpeg decodes the AMR-NB or AMR-WB audio from the 3G2 container and outputs uncompressed PCM in the WAV container (RIFF headers + raw PCM data). The default output is 16-bit signed little-endian PCM at 44.1 kHz, specified with '-acodec pcm_s16le'. The video track is discarded with -vn. WAV stores raw samples at approximately 10 MB per minute for 44.1 kHz stereo audio. The RIFF header contains channel count, sample rate, bit depth, and data size.
WAV stores the decoded audio with zero compression — every PCM sample is preserved exactly as decoded. However, the quality ceiling is determined by the 3G2 source: AMR-NB audio at 8 kHz contains only frequencies up to 3.4 kHz, and no format conversion can restore the higher frequencies that were never captured. The WAV output is a perfect, uncompressed representation of whatever the phone originally recorded.
