Convert OGG to AAC
About OGG
Ogg Vorbis is a free and open-source alternative to MP3 and AAC. It's known for providing better audio quality than MP3 at similar bitrates. The 'Ogg' part is the container format, capable of holding various types of media, while 'Vorbis' is the specific audio encoding. Its open nature means it's not restricted by patents, making it a popular choice for open-source software, games, and web content.
About AAC
Advanced Audio Coding (AAC) was designed to be the successor to the MP3 format. It generally delivers higher-quality audio than MP3 at the same bitrate, especially at lower bitrates. AAC is the standard audio format for YouTube, Apple's iTunes, and is widely used on mobile devices and digital video broadcasting. It's a very efficient codec, but it is a patented technology, which has implications for its use in some open-source projects.

Frequently Asked Questions
Is OGG better than MP3?
From a purely technical standpoint, Ogg Vorbis is often considered to provide slightly better quality than MP3 at the same bitrate. However, MP3 has much wider hardware and software support. The choice often comes down to compatibility needs versus the desire for a completely open-source format.
Where is the OGG format used?
OGG is widely used in video games, open-source applications, and for web streaming, particularly on platforms that prioritize open standards, like Wikipedia. It's also the format used for audio files on Spotify's desktop client.
Is AAC the same as M4A?
Not exactly. AAC is the audio encoding standard (the codec). M4A is a file extension for an audio file that is encoded with AAC. So, an .m4a file is a container, and the audio inside is typically AAC-encoded. Think of AAC as the engine and M4A as the car.
Which is better, AAC or MP3?
Most listening tests conclude that AAC produces better audio quality than MP3 at the same bitrate. This advantage is more pronounced at lower bitrates (e.g., 128kbps and below). For this reason, many streaming services have adopted AAC.
