It is used to encode digital audio data in a highly efficient manner, allowing for high-quality sound reproduction while minimizing file size. ATRAC is commonly used in Sony’s audio products, … Read more
I. What is M4A? M4A stands for MPEG-4 Audio. It is a file extension used for audio files encoded with the MPEG-4 Part 14 multimedia container format. M4A files are similar to MP3 files but offer better sound quality and smaller file sizes. The format was developed by Apple Inc. and is commonly used for … Read more
What is LPCM (Linear Pulse Code Modulation)? LPCM, or Linear Pulse Code Modulation, is a method used to digitally represent analog audio signals. It is a form of pulse-code modulation (PCM) where the amplitude of the analog signal is sampled at regular intervals and quantized into a series of digital values. LPCM is a widely … Read more
What is HRA (High-Resolution Audio)? High-Resolution Audio (HRA) refers to audio files that have a higher resolution and quality than standard audio formats such as MP3 or CD. HRA files are typically encoded with a higher bit depth and sample rate, resulting in more accurate and detailed sound reproduction. HRA is often considered to be … Read more
What is a Fraunhofer Codec? A Fraunhofer Codec is a type of audio codec developed by the Fraunhofer Institute for Integrated Circuits in Germany. Codecs, short for coder-decoder, are used to compress and decompress audio files in order to reduce file size while maintaining audio quality. The Fraunhofer Institute is known for its contributions to … Read more
What is OGG Vorbis? OGG Vorbis is an open-source audio compression format that is designed to provide high-quality audio at lower bitrates than other popular audio formats. It was developed by the Xiph.Org Foundation as a free alternative to proprietary audio codecs like MP3. OGG Vorbis uses a lossy compression algorithm to reduce the size … Read more
