How 3G2 turns into WAV: audio-stream extraction

Converter.now selects the audio stream in 3G2, leaves the picture stream out, and encodes that sound as WAV. The result is audio, not a silent copy of the video. The 3G2 demultiplexer reads a CDMA-era 3GPP2 track layout and identifies its constrained mobile video, audio, rotation, timing, and metadata profile. WAV delivery writes a RIFF waveform whose PCM precision, rate, channels, channel mask, peaks, and large file size matter more than codec branding.

Decoded media - A 3GPP2 mobile-media container designed for CDMA-era phone video and audio. Encoded delivery profile - A waveform container written here as uncompressed 16-bit PCM audio.

Reading 3G2 correctly and satisfying what WAV expects

3G2

What can fail when 3G2 video container is interpreted

Its codec and metadata expectations are narrower than modern MP4, and current players may not recognize the extension.

WAV

What Waveform Audio cannot safely promise

PCM WAV can be much larger than delivery audio, and converting high-bit-depth material to 16-bit changes sample precision.

ENGINE

How the WAV writer handles this route

The verified WAV profile writes 16-bit little-endian PCM rather than a perceptual delivery codec.

How to confirm the converted WAV actually works

BEFORE

Record the 3G2 evidence before conversion

Inspect video and audio codecs, dimensions, frame rate, rotation, duration, sync, and playback on the required device.

AFTER

Test the WAV file in its receiving workflow

Compare duration, sample rate, 16-bit depth, channels, peaks, and audible clipping.

When to actually choose 3G2 to WAV

Choose this route to deliver dialogue, music, or a soundtrack to a system that accepts WAV; keep 3G2 when its pictures, captions, or visual timing still matter.

What changes between the 3G2 model and the WAV deliverable

The source stores a 3GPP2 mobile-media container designed for CDMA-era phone video and audio; the destination stores a waveform container written here as uncompressed 16-bit PCM audio. Compare application metadata after that structural change.
3G2 and WAV use different metadata conventions, so application-specific fields should be treated as optional until verified.
