Encoders compress and convert data from one format to another, often used for audio and video. They maintain sound quality while reducing file size and can bridge the gap between older and newer technology.
Encoders are software programs used to compress information. Often, their function will also allow data to be converted from one format to another. While there are several types of programs that accomplish this for text data, the encoder is usually associated with audio and video.
One of the common uses of an encoder has to do with converting audio files from a native format to one that matches a specific player. For example, the program would be used to compress and convert a WAV file into a file type compatible with an MP3 player. The WAV file would be compressed to a fraction of its original size and usually wouldn’t have a significant impact on the sound quality of the converted file.
Maintaining sound quality while significantly reducing the size of the original file is critical to how the encoder does its job. The idea is to maintain code integrity while creating the proper encryption codes that are relevant to the new format. In some cases, this can add redundancies to the converted file. Other times, the program can minimize redundancy. The exact configuration of the original file will dictate what needs to be done to compress and convert the audio or video file.
The encoder can also help bridge the gap between older technology and the latest portable portable devices that store music and files. It is inherent in the function of devices that allow you to create music files from vinyl records. In this application, the software helps convert the older analog signal of vinyl recordings into a bit stream and file format that can be loaded onto a CD or stored on a computer. If necessary, the newly created audio file can be converted again to another digital format and uploaded to a portable device.
