Preserve Audio from Old Mobile Videos

Have 3G2 videos from an old CDMA phone with audio you want to keep? Whether it's a voicemail, voice memo, or precious recording from the 2000s, extracting the audio as FLAC ensures you preserve every detail in lossless format.

3G2 files contain compressed audio (usually AMR or AAC). Converting to FLAC won't improve quality beyond the original, but it prevents any further quality loss if you need to edit or re-encode later.

How to Convert 3G2 to FLAC

  1. Upload your 3G2 file - Select your legacy mobile video file
  2. Confirm FLAC output - Audio extracts as lossless FLAC
  3. Download your file - Get your audio ready for archival or editing

Conversion runs in your browser. No software installation required.

Why Choose FLAC for 3G2 Audio?

  • Lossless preservation - No quality loss during extraction
  • Edit-friendly - Perfect for audio cleanup or enhancement
  • Future-proof - Re-encode to any format later without degradation
  • Wide support - FLAC plays on most modern devices and software

When to Use This Conversion

Archiving Voice Recordings

Old voicemails or voice memos from CDMA phones often exist only as 3G2 files. Extract to FLAC and store securely.

Audio Editing Projects

Need to clean up or enhance audio from old mobile video? FLAC gives you a lossless working copy for audio software.

Alternative Formats

  • Choose 3G2 to MP3: Smaller files for casual listening or sharing
  • Choose 3G2 to WAV: Uncompressed audio for maximum editing compatibility
  • Choose 3G2 to MP4: Keep video and audio together in modern format

Works on Any Device

Browser-based conversion works everywhere:

  • Windows, Mac, Linux
  • Chrome, Firefox, Safari, Edge
  • iPhone, iPad, Android

Pro Tip

Extract to FLAC first if you plan to clean up old voice recordings. Lossless format gives audio editors the best source material to work with, even if the original quality was limited.

Common Mistake

Expecting FLAC to make old 3G2 audio sound better. FLAC preserves quality but can't create detail that wasn't in the original. Manage expectations for legacy mobile recordings.

Best For

Archiving irreplaceable audio from old CDMA phone recordings. Voice memos, old voicemails, or early mobile videos where the audio matters more than the tiny video.

Not Recommended

Casual listening. FLAC files are larger than MP3 with no audible benefit for low-quality 3G2 sources. Use MP3 if you just want to play the audio.

Frequently Asked Questions

No. FLAC preserves the existing quality but cannot enhance it. 3G2 audio is typically AMR or AAC compressed. The FLAC output will be lossless but limited by the original recording quality.

3G2 files typically contain AMR (Adaptive Multi-Rate) or AAC audio. AMR was designed for voice and has limited quality. AAC offers better fidelity. Your FLAC output quality depends on which codec the original used.

Use FLAC if you plan to edit the audio or want a lossless archive. Use MP3 if you just need to listen or share. Given 3G2's low original quality, MP3 at 256kbps is often sufficient for casual use.

FLAC files from 3G2 sources are typically small because the original audio is low bitrate. A 1-minute 3G2 video might produce a 2-5MB FLAC file, compared to under 1MB for MP3.

Yes. Our converter works in mobile browsers including Safari on iPhone and Chrome on Android. Upload your 3G2, convert to FLAC, and save to your device.

FLAC is a modern, widely supported format. 3G2 is obsolete and many devices won't play it. If you only need the audio, FLAC is more practical and easier to work with.
