Sound formats
WAV: A WAV is an audio file that uses a standard digital audio file format utilised for storing waveform data. It allows the audio recordings to be saved in a variety of different sampling rates.
AIFF: The AIFF file format was introduced in 1988 and was populated and used by Apple macintosh computer systems. Despite apple frequenting this file format it was actually developed based on Electronic arts interchange file format which is called IFF.
WMA: WMA file format is a file extension used with windows media player which can be found installed on the majority of microsoft computers. WMA stands for windows media audio and this is because it is used as an audio file which is sound based and nowadays competes with their well known competitors who developed mp3.
MP3: Mp3 is a coding format for digital audio. Originally defined as the third audio format of the m peg 1 standard. Society today will know mp3 as it is one of the most commonly use audio file systems and can be used for a wide variety of audio products such as downloading ad converting songs off the internet to then store on a phone or PC.
Storage
Flash drives: A small electronic device containing flash memory that is used for storing data or transferring it to or from a computer or digital camera as well as many other devices. Flash drives can also be referred to a usb's which do the same jobs.
Hard drive: A disk drive used to read from and write to a hard disk. It is a fn electromechanical data storage device that used magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks coated with magnetic material.
Cloud storage: Cloud storage is a model of computer data storage in which the digital data is stored in logical pools. The physical storage spans multiple servers, and the physical environment is typically owned and managed by some sort of hosting company.
Compression
DRC: DRC which stands for Dynamic range compression or simply compression is an audio signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds thus reducing or compressing an audio signals dynamic range.
Downward & upward compression: A limiter is an extreme type of downward compression. Upward compression increases the loudness of sounds below a certain threshold while leaving louder sounds unaffected. Both downward and upward compression reduce the dynamic range of an audio signal.
Size versus quality:
Lossy: Lossy compression is most commonly used to compress multimedia data( audio, video and images). These are used quite often in applications such as streaming media and internet telephony.
Often lossy compression is used in media when it comes to live broadcasts.
Lossless: Lossless compression is typically required for text and data files, such as bank records and text articles. It is a class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data.
Bit rate: In telecommunications and computing bit rate is the number of bits that are conveyed or processed per unit of time. So bit rate is the number of bits per second that can be transmitted along a digital network.
file size: A file size is measured in bytes as opposed to bits. A file size is a measure of how much data a computer file contains or alternately how much storage it consumes. Typically file size is expressed in units of measurement based on byte.
Pros & cons:
sounds formats: Pro's can be that one of the file types can be converted into another if need be.
cons: Some of these file formats may not work correctly
Storage: Pros could be that a flash drive can portably save important files.
cons: some storage files may not be able to save data which can be a potential problem.
Compression: Pros are easy to operate and allows for a more smoother quality of sound to be processed.
Cons are that there may be an incorrect portion of sound which is processed resulting in the fact that you may have to restart it.
