Unit 16 LO2-P2 Task 4 - Sound Elements Production Report on Experimenting and Producing sound

Audio considerations report

With recording audio there are a lot of things you need to make sure are correct and if they aren't then some things can go wrong. Some of the important things are, sound format type, storage/file size, compressions and size versus quality.

Sound Formatting
 
WMA: WMA is Microsoft's is its own file type/sound format. It is also quite similar to MP3 and AAC, but it doesn't really have any advantages over any of the other sounds formats and the support of the file type is not very good, and people would very rarely compress something to this format/ file type.

MP3: This is the most common lossy format. Many people put their music into the MP3 format on their phones because it takes up less space than a lossless file and MP3 is supported by a ton of websites, apps and devices. MP3 is one of the most commonly used file types especially for music because it is very easy to download or convert a file type into this format.

AAC: AAC is a lossy format which is considered to be very similar to the MP3 style sound format. Apple iTunes have specifically made this sound format very popular as it has all the same components and capabilities and compatibility with devices as MP3. AAC is mainly only used through iTunes though because mostly people will just use MP3 for things such as downloading music to then put it on a usb then into the car. A downside of AAC is that only iTunes use it so compatibility wise it wouldn't work that well.

Storage/File size

USB: A usb is a portable storage stick which can hold very large amounts of data depending on its storage size. This device allows for extremely easy access to files on the stick. So, it is a very easy transfer from one computer to another. The main use of it is for complete access to your work and it is almost compatible with all operating systems. USBs are also small in size and can be easily lost which is a big downside to them.

SSD: An SSD is a Solid-State hard drive. In this day and age, it is the most used hard drive. It used to just be a normal HDD Hard drive, but they have become so slow, computers have become a lot quicker, which then means the computers storage needs to improve and that's where the SSD comes into hand. It is now recommended to everyone that they get an SSD because it is 100 times quicker than a normal hard drive. On the other hand, these SSDs are very expensive and even the smallest storage size which is about 120GB and even that costs about £90.

Cloud: Cloud has only been introduced recently in the last two decades and it still quite a new way of storing data. In some ways cloud is one of the best places to store data because of how inexpensive it is and how you could have as much data stored on there with a limit but then you could pay for more storage all the time, so it is very efficient. But on the other hand, cloud storage could also be a very bad option for storage because, in some instances you could forget to save something, and it could all be gone. The servers could crash, and all your data could disappear. Those are just some negatives.

Compression

DRC: DRC is an electronic effect that lowers the volume of loud sounds or increases the volume of quiet sounds by narrowing or compressing the audio signal of that audio. Downward compression is when the louder sounds are made quieter. If the audio is too loud and above a particular decibel or above a specific level, then downward compression will be needed but it is below that decibel or below the level then that audio will be left alone. On the other hand, there is something called upward compression where it has the same concept but the opposite way. If the sound is too quiet and below the specific decibel or below the level, then the volume of the sound will be increased.

Size Versus Quality

For example, if i decided to download a song I personally would rather have a song with good quality rather than bad but the downside to the good quality of the song is that the file size of the song would be larger than the song with a worse quality. In all situations I would take the quality of the song 100%. But if for instance there was a situation where all I needed were just a massive number of songs and the quality did not matter then I would take a smaller file size for all of them so i could fit more songs in the storage for example the USB, or for example the SSD.
