How the two formats differ on the things that change your result.
| Specification | 3GP Audio (source) | AIFF (result) |
|---|---|---|
| Container | 3GPP (audio-only) | IFF / AIFF |
| Developed by | 3GPP | Apple |
| Introduced | 2001 | 1988 |
| Audio codecs | AMR-NB, AMR-WB, AAC-LC | PCM |
| Compression | Lossy | Uncompressed |
| Max sample rate | 16 kHz | 192 kHz |
| Max channels | 2 | 8 |
| Gapless playback | No | Yes |
| Metadata / tags | 3GPP asset boxes | ID3 chunk (limited) |
| Approx. file size | 0.06–0.48 MB per minute | 10–32 MB per minute |
| Licensing | Patent-licensed | Royalty-free |
| Plays natively on | Native: Android · Needs a player: Windows, macOS, iOS | Native: macOS, iOS · Needs a player: Windows, Android, Web browsers |
| Best for | voice recordings, phone recordings, low-bandwidth delivery | studio editing, the Apple ecosystem, mastering |
3GP Audio is already lossy, so converting to AIFF cannot restore detail that the original encoder discarded. What you gain is a format that survives further editing without stacking up more loss. Expect the file to grow from roughly 0.3 MB per minute to about 21 MB per minute, around 78 times larger.
Compatibility is the main win here: AIFF plays natively on macOS and iOS, where 3GP Audio needs a separate player, so the result works without asking anyone to install anything.
The two formats are aimed at different jobs. 3GP Audio is typically used for voice recordings, phone recordings, low-bandwidth delivery, while AIFF is the usual pick for studio editing, the Apple ecosystem, mastering. That difference in intent is what most of the specification gaps above come from.
Expect metadata to be rewritten rather than copied: 3GPP asset boxes in the source becomes ID3 chunk (limited) in the result. Standard fields map cleanly; niche custom tags often do not.
This page converts 3GP Audio files, stored in the 3GPP (audio-only) container since 2001, into AIFF, which uses IFF / AIFF and dates from 1988. The differences between the two containers decide what changes in the result.
3GP Audio comes from 3GPP and dates to 2001. It holds lossy-compressed audio (AMR-NB, AMR-WB, or AAC-LC), and that sets the ceiling for anything converted out of it.
AIFF comes from Apple and dates to 1988. It carries uncompressed audio (PCM), and without installing anything it plays on macOS and iOS.
After converting your file, you can use Scriptivox transcription services to convert your audio to text. Perfect for meetings, interviews, podcasts, and more.
