Although LPCM can be stored on a computer as a raw audio formatit is usually stored in a. WAV and AIFF are designed to store a wide variety of audio formats, lossless and lossy; they just add a small, metadata -containing header before the audio data to declare the format of the audio data, such as LPCM with a particular sample ratebit depthendianness and number of channels.
Among other enhancements, BWF allows more robust metadata to be stored in the file. See European Broadcasting Union: This is the primary recording format used in many professional audio workstations in the television and film industry. BWF files include a standardized timestamp reference which allows for easy synchronization with a separate picture element.
Lossless compressed audio format[ edit ] A lossless compressed format stores data in less space without losing any information. The original, uncompressed data can be recreated from the compressed version.
Uncompressed audio formats encode both sound and silence with the same number of bits per unit of time. Encoding an uncompressed minute of absolute silence produces a file of the same size as encoding an uncompressed minute of music. In a lossless compressed format, however, the music would occupy a smaller file than an uncompressed format and the silence would take up almost no space at all.
They provide a compression ratio of about 2: Development in lossless compression formats aims to reduce processing time while maintaining a good compression ratio. Lossy compressed audio format[ edit ] Lossy compression enables even greater reductions in file size by removing some of the audio information and simplifying the data.
This of course results in a reduction in audio quality, but a variety of techniques are used, mainly by exploiting psychoacousticsto remove the parts of the sound that have the least effect on perceived quality, and to minimize the amount of audible noise added during the process.
Most formats offer a range of degrees of compression, generally measured in bit rate. The lower the rate, the smaller the file and the more significant the quality loss. List of formats[ edit ].The is a small color video camera with audio that also takes photos.
