Image Compression: - Why Do Math

In digital multimedia, bit rate refers to the number of bits used per second to represent a continuous medium such as audio or video after source coding (data compression). The encoding bit rate of a multimedia file is its size in bytes divided by the playback time of the recording (in seconds), multiplied by eight. For realtime streaming multimedia, the encoding bit rate is the goodput that is required to avoid in… WebJun 12, 2014 · So, regardless of the compression level that is chosen, FLAC will always decode into the exact uncompressed audio track (bit for bit). The difference between the compression levels, then, is the resulting file size.
