Audio Manipulation
Digital Audio
Digital sound is any sound that is represented in a binary system. The binary encoding represents the instructions required to recreate a sound. The quality of the sound is determined by bit rate and bit depth. Bit rate is how fast the instructions can be transported while bit rate represents the accuracy of the sound.
Audio Processing
Modifying audio is done by changing the values of bits. These bits are changed to make the frequency, pitch, tone, and quality. Because sound works in waves, mathematical formulas are used to effectively edit audio.
Audio Compression
Audio compression is used to make file sizes smaller. There are two main types of compression: lossy and lossless. With lossless compression, no quality will be lost. The stable quality is at the cost of compressibility. Lossless data formats can also be reconstructed into the original format unlike lossy formats. Lossy compressions result in smaller file sizes at the cost of quality. Unnecessary data is destroyed to make the file size smaller. Because some of the data is destroyed, it cannot be reconstructed into the original file format. The type of data compression used depends on the data being transferred.
