Low bit is a lossy encoding method that uses a small amount of bits, resulting in poor quality with artifacts. Some musicians intentionally use low bit for faster download rates. High bit rate is lossless and produces clear quality. Low bit is easier to download and store, but has suboptimal quality.
Low bit, also known as low bitrate and lobit, is an encoding method in which a small amount of bits are used; in the process, the compression is lossy and creates artifacts. It is used for videos, images and songs and is generally considered to be of poor quality. Some artists, especially musicians, use low bit intentionally, because they believe their song can be enjoyed despite its bitrate, which helps download rates. Another benefit of the low bitrate is that the file will use significantly less memory than a high bitrate file, making it easier to archive.
When a file is encoded, it uses a certain amount of bits depending on the medium, the size or duration of the file and its quality. For optimal encoding, lossless compression is used, which means that little or no compression quality is lost. When someone listens to clear music, watches a high quality movie, or sees a clear digital image, this is an example of a high bit rate.
Low-bit compression is the exact opposite. This is a type of lossy compression, which means that quality will be lost. It also produces artifacts which means that an image or movie will have pixelation and a song will crackle or have areas where the music fades out unexpectedly. Artifacts occur because the optimal number of bits, or memory, is not used during encryption, so the medium degrades to accommodate the specified amount of bits.
Some musicians purposely make music with low bit compression, feeling that the song should be enjoyed because it sounds good, not because it has a good compression rate. The most common music genre that does this is punk, but other genres also use low bitrate compression. This form of music is not as popular as high bitrate music, so low bitrate albums are usually only sold online. The amount of memory required for a low bitrate album is approximately the same amount of memory required for a high bitrate song.
While there are a number of problems with using low-bit compression, such as suboptimal file quality, there are some benefits to this compression system. A low bitrate file takes much less time to download because there are fewer bits in the file. Storing the file is also easier, because fewer bits are used. The more bits in a file, the more memory is required, which may be difficult to support on computers with a small hard drive or dialup networks that download at slow speeds.
