The OGG file format and .ogg file extension refer to the open source container format developed and maintained by the Xiph.Org Foundation. The format has been in development since the early 90's and initially was designed as an open format for audio compression. Later iterations has seen the format revised into a full audio and video container format with compression codec support of different standards. OGG can be used both in compressed or uncompressed ways and is compatible with different lossy and lossless codecs both for audio and for video. Text can also be added into OGG files as an overlay, all packaged within a single file.
The advanced audio coding audio format or AAC format for short is a standardized audio encoding format designed to succeed the popularized mp3 format. It is the result of the collaborative efforts of several companies including bell labs, Nokia, and Sony among others. It was initially released in 1997 as part of the lossy digital audio compression family of audio encoding formats. AAC enjoys a wealth of native compatibility and support by different platforms, hardware, and software applications including video game consoles such as the PlayStation 3, Nintendo DSi, and platforms such as Android, and YouTube. Today even diverse hardware such as in dash car audio players have native support for the format.
FreeFileConvert uses tuned encoding for OGG to AAC conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload OGG files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized AAC results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent AAC audio with dependable progress tracking.
Though OGG is versatile in the number of codecs it supports, typically only free codecs developed by the Xiph.org organization are used for encoding and decoding. From the lossy family of codecs, audio can be encoded using Speex, Vorbis, or Opus. Whereas Lossless or uncompressed encoding can be done using FLAC and OggPCM respectively. To be competitive against its closest rivals such as Windows Media Video, Real Video and MPEG-4, lossy video compression codec Theora is often used but a lossless format, DIRAC, can also be used to encode video streams.
The AAC supports stereo playback at a maximum and acceptably modest 96 kilobits per second. Sample frequencies can range from 8 to 96 kilo hertz, and maximum number of supported channels is 48. Resulting AAC file sizes are typically smaller in comparison with those of its closest rival format mp3.
