FAQ
Got questions?
AVI files from the DivX/Xvid era (1999–2010) mainly contain MP3 (MPEG-1 Audio Layer III) or AC-3 (Dolby Digital). DVD rips in AVI with DivX or Xvid almost always use MP3 at 128 kbps in stereo or joint stereo, generated by the LAME encoder. AVI files from digitized analog camcorder recordings may contain PCM (standard WAVE inside the AVI RIFF). Some newer-encoded AVI files may contain AAC, though this is unusual. The AVI container (Audio Video Interleave), specified by Microsoft in 1992 as part of the RIFF standard, is technically limited: it supports no more than two audio tracks, has no native support for chapters or text subtitles, and has known limitations for files over 2 GB (the OpenDML extension extends this to 4 GB). The tool detects the codec automatically.
OGG is an open-source multimedia container and Vorbis is the audio codec it typically holds. Vorbis was developed by Xiph.org starting in 2000 as a free alternative to MP3 (whose patents did not fully expire until 2017). Vorbis advantages over MP3 are technical: Vorbis uses more modern psychoacoustics based on MDCT with variable windows (256, 512, 1024, 2048, 4096, and 8192 samples), producing fewer artifacts on transients and better quality at low bitrates (64–128 kbps). At 128 kbps, Vorbis perceptually outperforms MP3 in most blind listening tests. Additionally, Vorbis has integrated metadata support (Vorbis Comment), no patent restrictions, and is the preferred audio format for game engines like Godot and for Linux platform distribution.
Yes, because both codecs are lossy. The MP3→Vorbis conversion involves two generations of compression: the audio was compressed to MP3 when creating the original AVI, and now it is decoded to PCM to be re-encoded to Vorbis. At output bitrates of 160 kbps or higher, the added degradation is minimal and practically inaudible. If the AVI has AC-3 audio (from a DVD rip), the degradation is similar. If it has PCM audio, only one generation is lost. For game engines or multimedia archives where exact quality is not critical, Vorbis at 128 kbps from an AVI with MP3 is perfectly adequate.
OGG Vorbis is the de facto standard audio format in indie game development and many AAA titles. Godot Engine uses OGG Vorbis as its native streaming audio format (for background music and long effects). Unity, Unreal Engine, and other engines accept it efficiently. The reasons are pragmatic: Vorbis has no license restrictions (royalty-free), has a small decoder footprint (important for embedded platforms), supports incremental streaming, and produces smaller files than MP3 at equivalent quality. Extracting audio from a movie or demo AVI to OGG is the natural step for reusing that audio as an asset in a game engine.
The original 1992 AVI format has a 2 GB limit due to 32-bit RIFF header limitations. To overcome this, the OpenDML extension (AVI 2.0) was created in 1996, extending the limit to 4 GB using additional indexes. Most modern encoders and players (VirtualDub, MPlayer, FFmpeg, VLC) generate and read OpenDML AVI without issues. The tool supports OpenDML AVI, but Convertir.ai's 500 MB upload limit constrains practical use to reasonable file sizes for in-browser processing. For larger files, consider splitting them first with VirtualDub.
Yes, with broad native support on both platforms. Android has natively supported OGG Vorbis playback since Android 1.0 (2008) via the OpenCore/Stagefright audio layer. Linux supports it widely: ALSA, PulseAudio, and PipeWire handle Vorbis without additional drivers, and players like Rhythmbox, Clementine, Amarok, Audacious, and VLC play it natively. Firefox and Chromium on Linux also play OGG Vorbis directly in the browser. It is the format of choice for audio distribution on open-source operating systems.
Convert AVI to OGG: extract audio from DivX/Xvid legacy video to free Vorbis format
The AVI (Audio Video Interleave) format was created by Microsoft in 1992 as part of the RIFF (Resource Interchange File Format) standard and dominated digital video distribution for over a decade. Its peak coincided with the digital video explosion during the DivX (1998–2004) and Xvid (2001–2010) era, when AVI files with DivX or Xvid compressed video and MP3 or AC-3 audio became the de facto standard for sharing movies and series on P2P networks like eMule and BitTorrent. The AVI container stores audio and video data in interleaved blocks inside a LIST movi structure, with an index at the end of the file (in AVI 1.0) or distributed throughout the file (in OpenDML/AVI 2.0, introduced in 1996 to overcome the 2 GB limit). OGG Vorbis, on the other hand, is the combination of the OGG container (designed by Xiph.org in 2000 for multimedia streaming) with the Vorbis codec (also from Xiph.org, conceived by Chris Montgomery as a free alternative to MP3 in 1993 and released in version 1.0 in 2002). Extracting AVI audio to OGG Vorbis modernizes the audio codec of legacy files to an open format with no patent restrictions, better perceptual quality at equivalent bitrates, and native support on Linux and Android.
The Vorbis codec implements a perceptual audio encoding architecture based on the MDCT (Modified Discrete Cosine Transform) with variable-size windows (256, 512, 1024, 2048, 4096, and 8192 samples), a frequency and time masking psychoacoustic model, and vector quantization with trained codebooks. This architecture produces perceptually superior results to MP3 (which uses fixed 576-sample windows) especially on musical transients and at low bitrates (64–128 kbps). Vorbis encoding uses a VBR quality system by default, where the quality parameter ranges from -1 to 10 with decimal steps: quality 3 produces approximately 112 kbps, quality 5 approximately 160 kbps, and quality 8 approximately 256 kbps. In comparison, AVI files from the DivX era almost always have constant bitrate (CBR) MP3 at 128 kbps, produced with the LAME encoder in versions 3.90–3.95 (the most used in 2002–2006). Converting that MP3 to Vorbis at quality 4–5 (128–160 kbps) yields very high perceptual transparency, and also results in a format with better support in modern ecosystems.
The main current use cases for AVI to OGG conversion are three. First, preservation and modernization of legacy video files: DivX/Xvid collections accumulated in the P2P era that need their audio codec updated for modern software and hardware players. Second, game audio asset creation: extracting sound effects, ambient music, or dialogue from game demos and cutscenes distributed in AVI (a common format for cutscenes in PlayStation 2 and PC games from 2000–2010) for reuse in independent projects. Godot Engine, the open-source engine with the strongest growth in the last decade (releasing version 4.0 in 2023), uses OGG Vorbis as the native format for AudioStreamOGGVorbis, the recommended stream type for music and long effects. Third, distribution on Linux and Android systems: OGG Vorbis has native support on Android since API Level 1 (Android 1.0, 2008) and on all Linux distributions via libvorbis and libvorbisfile. Convertir.ai performs AVI→OGG processing entirely in the browser via WebAssembly, with demuxing of the RIFF-AVI container, decoding of the original audio codec (libmp3lame decode, libac3 for AC-3, or direct PCM), and Vorbis encoding with libvorbisenc, without any byte of the AVI file leaving the user's device.
