The codec to encode the audio track. Codec "Without reencoding" copies the audio stream from the input file into output without re-encoding if possible.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).
Set the sample rate of the audio. Music with a full spectrum (20 Hz — 20 kHz) requires values not lower than 44.1 kHz to achieve transparency. More info can be found on the wiki.

3g2

3G2 (3GPP2 file format) is a multimedia container developed by the 3rd Generation Partnership Project 2 for use on CDMA2000 mobile networks. Built on the ISO base media file format (MPEG-4 Part 12), it stores video encoded with H.263 or MPEG-4 Visual alongside audio in AMR, EVRC, or AAC codecs. The specification was first published in December 2003 to provide a standardized way for CDMA-based phones and networks to handle multimedia messaging and video playback. 3G2 files are engineered for extremely low-bandwidth conditions, achieving playable video quality at bit rates as low as 30-60 kbps. This makes the format especially efficient for mobile video capture on devices with limited processing power and storage. The container supports multiple tracks, timed text for subtitles, and embedded metadata. One significant benefit is near-universal compatibility with CDMA handsets from the mid-2000s era, ensuring reliable playback across a wide range of mobile devices. Though newer formats like MP4 have superseded 3G2 for most purposes, it remains useful for working with legacy mobile content and for situations where minimal file size is the primary concern.

oga

OGA is the audio-only file extension within the Ogg container framework maintained by the Xiph.Org Foundation. While .ogg traditionally served as a catch-all extension for any Ogg-encapsulated stream, the introduction of .oga in 2007 brought clarity by explicitly signaling that a file contains only audio data. Under the hood, OGA files can carry audio encoded with Vorbis, FLAC, Speex, or Opus — the container is codec-agnostic, serving as a transport wrapper with support for chained logical bitstreams and granule-based seeking. One benefit of OGA is interoperability: applications that encounter the .oga extension can optimize for audio-only playback without probing for video tracks, resulting in faster load times and lower memory usage. Because the Ogg container and its associated codecs are entirely open-source and royalty-free, OGA avoids the patent licensing complexities that affect proprietary formats. The format supports Vorbis comment metadata for tagging artist, album, and track information in a standardized way. OGA plays natively in Firefox, Chromium-based browsers, VLC, and most Linux desktop environments, making it a practical choice for web audio distribution and archival workflows.

Frequently Asked Questions

Why should I convert 3G2 to OGA?

OGA is the audio-only variant of the Ogg container — open-source and royalty-free. Converting 3G2 to OGA provides Vorbis-encoded audio for open platforms.

How can I open OGA files?

OGA is supported by VLC, foobar2000, Audacious, and Linux-based music players supporting Ogg containers.

Can I convert 3G2 to OGA on my phone?

Absolutely. The converter runs entirely in your mobile browser on iOS or Android — upload 3G2, pick OGA, and save the output to your device.

How long does 3G2 to OGA conversion take?

Our cloud servers handle the processing quickly. Typical 3G2 recordings convert to OGA in under a minute, though larger files naturally take longer.

Can I batch convert multiple 3G2 files?

Yes — upload several 3G2 files at once and convert them all to OGA in a single session. Each file processes in parallel on our cloud infrastructure.

Do I need to install anything?

Nothing to install — everything happens in the browser. Open convertio.tools, upload your 3G2, and receive the OGA without any software setup.
