Need Speech Audio from 3G2 Videos?
3G2 files from older CDMA phones contain video and audio you may want to preserve. Converting to AMR extracts just the audio in a format optimized for speech-perfect for voice memos, calls, or spoken content.
AMR (Adaptive Multi-Rate) creates tiny files ideal for voice. A minute of speech takes just 60-90KB, making it efficient for storage and sharing.
How to Convert 3G2 to AMR
- Upload your 3G2 file - Select your mobile video file
- Confirm AMR output - Optimized for speech compression
- Download your file - Get compact audio instantly
Conversion happens in your browser-fast and private.
Why Convert to AMR?
Smallest Voice Files
AMR uses variable bitrates from 4.75 to 12.2 kbps. For voice content, it delivers clear speech at a fraction of the file size compared to MP3.
Mobile-Friendly Format
AMR was designed for mobile networks. The files work on feature phones, smartphones, and any device that handles voice recordings.
AMR Technical Details
- Sample rate - 8 kHz narrowband (voice optimized)
- Bitrate range - 4.75 to 12.2 kbps variable
- Frequency range - 200-3400 Hz (speech focused)
- Typical file size - 60-90 KB per minute of audio
AMR is efficient for voice but not ideal for music. For music extraction, consider 3G2 to MP3 instead.
