The 3GA audio format is a lesser-known but widely used mobile audio container designed primarily for voice recordings and multimedia messaging. If you've ever recorded audio on an older Samsung phone—or extracted sound from a 3GP video—chances are you’ve encountered the .3ga file extension.
3GA
What Is a 3GA File?
A 3GA file is an audio-only file based on the 3GP multimedia container. It is commonly produced by mobile phones—especially older Samsung and Android devices—when recording voice notes or audio clips.
Key characteristics:
Audio-only version of the 3GP format
Small file size
Designed for low-bandwidth mobile use
Often uses AMR, AAC, or MP3 codecs
Ideal for voice memos, MMS, and low-storage devices
Because 3GA uses efficient compression, it is well-suited for recording speech, not high-fidelity music.
Which Codecs Does 3GA Use?
3GA can contain multiple audio codecs depending on the device and settings:
Most common codecs:
AMR-NB (Adaptive Multi-Rate Narrowband) – optimized for speech
AMR-WB (Wideband) – better clarity for voice
AAC (Advanced Audio Coding) – higher-quality sound
MP3 – more compatibility, but less common for 3GA
What this means for quality:
AMR = best for voice, smallest size
AAC = best for general audio, better quality
MP3 = best for compatibility
Where Are 3GA Files Commonly Used?
Although not as common in modern smartphones, 3GA is still found in:
Older Samsung & Android voice recorders
Feature phones
Mobile messaging apps
Low-bandwidth audio recordings
Extracted audio from 3GP videos
If you’ve retrieved audio from an old device, you might have multiple 3GA files stored in your voice notes folder.
How to Open 3GA Files
Not all players support 3GA out of the box, but several reliable options exist.
Best apps for opening 3GA files:
VLC Media Player (Windows, macOS, Linux, Android, iOS)
KMPlayer
QuickTime (with codec support)
Audacity (with FFmpeg)
Samsung Voice Recorder (native)
Android system apps
VLC is the easiest solution because it supports nearly every mobile audio codec.
Is 3GA a Good Format? Pros & Cons
Advantages
Tiny file sizes
Great for voice recordings
Efficient for low storage & low bandwidth
Supported by many older phones
Disadvantages
Not ideal for music
Lower audio quality than modern formats
Limited compatibility on modern devices
Often requires conversion
3GA is functional but outdated compared to M4A, MP3, or WAV.
Should You Still Use 3GA in 2025?
In most cases—no. The format is outdated and limited.
However, 3GA is still great for:
Archiving audio from old phones
Extracting voice memos
Low-size recordings on legacy devices
For anything else, modern formats provide better quality and compatibility.
Conclusion
What Is the 3GA Format Good For?
The 3GA audio format is an efficient, speech-focused mobile audio container designed for older phones and MMS messaging. While it delivers very small file sizes, it lacks the audio quality and compatibility of modern formats like MP3 and M4A.
