Introduction to Audio Compression
Audio compression is a process that reduces the dynamic range of an audio signal, making it possible to store and transmit audio files more efficiently. The dynamic range of an audio signal refers to the difference between the loudest and quietest parts of the signal. By reducing the dynamic range, audio compression makes it possible to reduce the file size of audio files, making them easier to store and transmit. Audio compression is essential for streaming music services, as it enables the efficient transmission of high-quality audio over the internet.
Types of Audio Compression
There are two main types of audio compression: lossless and lossy. Lossless compression reduces the file size of an audio file without discarding any of the audio data. This type of compression is used in formats like FLAC and ALAC. Lossy compression, on the other hand, discards some of the audio data to reduce the file size. This type of compression is used in formats like MP3 and AAC. Lossy compression is more commonly used in streaming music services, as it provides a good balance between file size and sound quality.
How Audio Compression Works
Audio compression works by analyzing the audio signal and identifying the parts that are less important to the human ear. These parts are then discarded or reduced in amplitude, resulting in a reduced file size. The compression algorithm used in audio compression is designed to preserve the most important aspects of the audio signal, such as the melody and rhythm. The compression algorithm used in Sonos devices is designed to provide high-quality sound while minimizing the file size.
