What is an MPG File?

MPG is a popular video format used for movies and digital video content. It often contains both video and audio streams. However, if you only need the audio track from MPG, converting it to AAC format can help reduce file size and improve compatibility with music players and mobile devices.

What is AAC and Why Use It?

AAC (Advanced Audio Coding) is a high-quality audio format widely supported by iOS, Android, Windows, and most streaming platforms. It offers better sound quality than MP3 at similar bitrates, making it ideal for converting videos to audio.

Using our free MPG to AAC converter, you can extract audio from videos for:

Podcasts
Voiceovers
Music
Ringtones
Audio Editing

Overview

AAC is the descendant of the MP3 format. It provides better sound quality using a similar bit rate as of MP3. Besides this, it uses lossy data compression but it has high standards of audio quality than of MP3. We can find this format on a number of platforms and Apple's iTunes is one such example that uses it as default audio format. Size of its file is much smaller which is approximately one-tenth of MP3 file. It also neglects the redundant information that is not even processed by the human ear and is often not noticed. Although, this format was introduced as MPEG-2 Part-7, yet, standardization was done by ISO/IEC as a part of the MPEG-2 and MPEG-4 families. It is also termed as MPEG-2 NBC (Non- Backward Compatible) because it is incompatible with MPEG-1 audio formats i.e. MP1, MP2, MP3.

Technical description

Modified discrete cosine transform(MDCT) algorithm is used by AAC which ensures that it provides high compression efficiency. MPEG-2 PART-7 has three default profiles namely Low Complexity (LC), Main Profile (Main) and Scalable Sample Rate (SSR). These profiles come with Perceptual Noise Substitution which enhances coding efficiency and provides excellent audio quality. Furthermore, it uses Auditory Masking to ignore the surplus information. This codec has come up with advanced features which are not available in the predecessor. These include additional sample rates ranging from 8 to 96 kHz, 48 Channels, better efficiency with a simpler filter bank, higher coding efficiency for stationary signals and higher coding accuracy for transient signals.

Overview

MPG/MPEG is a file extension that uses MPEG-1 and MPEG-2 codecs for video and audio files. The lossy compression in this format leads to enhancement of the streaming and downloading speed. That is why it is very popular and widely accepted for movies. This format is compatible with both Mac/Macintosh and Windows including some other portable devices. The files that are encoded using this codec provide compressed data that has small size but the quality is not sacrificed at all. It just deletes or neglects the superfluous information that can not be noticed by the human ear. This lossy encoding takes less storage space to store data. Although this format is not efficient enough to provide excellent quality, yet, it is used most of the times due to its higher level of compatibility.

Technical description

The compressed ratio in digital video files under this format is 26:1 and for audio files it is 6:1.The bit rate in MPEG-1 is about 1.5 million bits per second and it is used to compress CD data., Besides this, MPEG-2 is designed especially for digital TV broadcast and DVD as it uses a bit rate above 4 million bits per second to compress both audios and videos. It should be noted that due to backwards compatibility with MPEG-1, video decoders have the ability to play a lower bit rate. It produces high quality of compressed files. Other uses of MPEG-2 is for Cable network, satellite and television stations; etc. Furthermore, it supports 5.1 multichannel audio.
