Research and explain when you would use the following sounds format and why?

An audio file format is a file format that stores digital audio data on a computer system. it can be either uncompressed or compressed to reduce the file size. There are many uncompressed formats and different sound formats such as wav, aiff, au, smp, voc, mp3, ra and vox.

sounds file formats
wav is a standard sound file format used mainly in windows.

mp3 format is the most popular format for downloading and storing music.

aiff the standard format for apple.

au is the standard format used by sun, Unix and java.

lossy compression

Lossy Compression is a compression method that encodes and compresses data by losing some of it in the process. This includes losing quality and some data. This can be noticed in audio because it will sound fuzzy and less clear than the original audio file.

Sample Rate is the number of samples per second. Bandwidth is the difference between the highest and lowest frequencies

Mono or monophonic describes a system where all the audio signals are mixed together and routed through a single audio channel. 

stereo sound systems have two independent audio signal channels, and the signals that are reproduced have a specific level and phase relationship to each other so that when played back through a suitable reproduction system, there will be an apparent image of the original sound source.

P2 

DSP digital signal procession is the manipulation of information signal to modify or improve it. It is used to turn an analog signal from a phone call in to digital and sent to a satellite and to the to her phone back into a analog signal. 

RAM Random Access memory. RAM is short term storage for recently open programs, tabs and files. If you have limited RAM space the more programs, tabs and files your open and use the slower all your memory will run and the slower the programs will run. This can effect sound files and quality of the sound as it can buffer, skip parts and jumps. 

PCM Pulse-code modulation is a method to used to digitally represent sampled signals.it is standard for computers. 

Multi-track recording is a method of sound recording that separates multiple sound sources to create a cohesive hole. This can be used if you have lots of free music samples that you want to put together. 

DAT Digital audio tape is a signal recording and playback hardware. This can be used to listen to old music on tapes for inspiration,  you can also use that type of sound as retro.

Analog is a type of signal.

Software plug-ins are extra content or additions to software for example extra audio tools like a mix deck. This could be use full if the software you are using doesn't have a particular tool that you need, you could add it in.

Software sequencer is a device that allows you to record, playback and edit by handling note and information in different ways E.G. MID or CV/Gate.
