Need help?How to Convert 3GPP to WAV
- Upload Your 3GPP File — Click "Choose Files" or drag and drop your 3GPP mobile video file. Only .3gpp files are accepted.
- Set Audio Channel — Under Audio Channel, choose Original, Mono, or Stereo.
- Set Sample Rate — Under Audio Sample Rate, choose from 8000 Hz through 48000 Hz. Use 44100 Hz for CD quality or 8000 Hz to match the original 3GPP voice quality.
- Trim (Optional) — Under Trim, set a Start Time and Duration in seconds or HH:MM:SS.sss format.
- Convert & Download — Click "Convert" and download your WAV file.
Why Convert 3GPP to WAV?
3GPP is a mobile video format from GSM networks containing low-quality AMR audio (typically 8-12 kbps). WAV stores uncompressed PCM audio — the standard for audio editing. Converting 3GPP to WAV extracts the audio as uncompressed PCM, which is useful for editing mobile voice recordings in Audacity, Adobe Audition, or other audio editors, preserving voicemail or phone recordings in a lossless format, preparing mobile audio for professional workflows that require WAV input, and archiving old phone recordings without further quality loss.
3GPP vs WAV Comparison
| Feature | 3GPP | WAV |
|---|---|---|
| Type | Mobile video + audio | Audio only (uncompressed) |
| Audio codec | AMR (voice-optimized) | PCM 16-bit Little Endian |
| Typical bitrate | 8-12 kbps | ~1411 kbps (CD quality) |
| Audio quality | Low (voice) | Perfect (lossless PCM) |
| File size (1 min) | 60-90 KB | ~10 MB at 44100 Hz |
| Platform | Mobile phones | Universal |
| Best for | Mobile voice recording | Audio editing, archival |
Sample Rate Guide
| Sample Rate | Quality | Best For |
|---|---|---|
| 8000 Hz | Telephone | Matches original 3GPP AMR quality |
| 22050 Hz | AM radio | Voice with some headroom |
| 44100 Hz | CD quality | Standard audio editing |
| 48000 Hz | Broadcast | Professional audio/video sync |
Why is the File Compression section not available?
WAV is an uncompressed PCM format — the default codec is PCM 16-bit Little Endian (PCM_S16LE). There are no compression options because the audio is stored as raw, uncompressed data.
Will converting to WAV improve the audio quality?
No. The original 3GPP AMR audio is low-quality (8-12 kbps). Converting to WAV preserves the current quality without further loss, but cannot recover data discarded by AMR compression. The WAV file will sound identical to the 3GPP source.
What sample rate should I use?
8000 Hz matches the original 3GPP AMR quality — using higher rates won't improve quality but increases file size. Use 44100 Hz if your audio editor requires CD-quality sample rate.
Can I trim the audio during conversion?
Yes. Under Trim, switch to "Trim" and enter a Start Time and Duration. This extracts a specific segment from the 3GPP recording.
How much larger will the WAV file be?
Significantly larger. A 90 KB 3GPP file (1 minute at 12 kbps) becomes roughly 10 MB as WAV at 44100 Hz stereo, or 960 KB at 8000 Hz mono. Use Mono channel and 8000 Hz sample rate to minimize size.
