Digital Music Formats in A Nutshell

http://www.soundinvestigationstudio.com/daw-digital-audio-workstation/

Digital audio has been around since long time ago, therefore there are lots of digital audio formats out there. Every audio format has its own advantages and disadvantages. They also have their own characters, so it should be enough for us to differentiate them. Now, we can put them into 3 big groups, the uncompressed, the lossy, and the lossless.

The uncompressed consists of 2 formats, they are WAV (Waveform Audio File Format) and AIFF (Audio Interchange File Format). WAV is for Windows devices and AIFF is for Apple devices. They can be converted to and from each other without degradation of quality. If you’re recording at home for the purposes of mixing, this is what you want to use because of its high quality, but they usually have very big file size.

The lossless. They are Free Lossless Audio Code (FLAC), Apple Lossless Audio Codec (ALAC), and Monkey’s Audio (APE). They are compressed using algorithms.  The difference between zipped files and lossless files is that lossless is designed specifically for audio, and so has better compression rates without any loss of quality.  Typically, you’re seeing little version of WAVs. If you want to do audio manipulation, you can convert back to a WAV or AIFF without any loss of quality. If you’ve got a great set of speakers, or earbuds, these formats will bring out the tones to showcase them.

The lossy. They are MP3 (MPEG 1 Audio Layer 3) and AAC (Advanced Audio Coding). In the MP3 and AAC, some degree of audio quality is sacrificed in exchange for a significant gain in file size.  Different lossy formats use different compression algorithms to store data, and so they typically vary in file size for comparable quality.  Lossy formats also use bitrate to refer to audio quality, which usually looks like “192 kbit/s” or “192 kbps.”  Higher bitrate means that more data is being pumped out, so there’s more preservation of detail. MP3 is the most common lossy audio codec today, but it offers lower music quality than the AAC’s at the same bitrate. Still, the lossy has the worst quality among the 3 big groups.

Which format you choose depends on what digital audio player you use, how much space you have, how big of a quality nitpicker you are, and other complex variables. Apple devices support only MP3, AAC, AIFF and ALAC while Windows and other devices support almost all of music formats. The lossy is designed to be an economy of hard drive space, but it has degradations of quality. The lossless is designed for those who want uncompressed music quality with smaller file size. The uncompressed is designed just for professional music creators.

Moral Value of The Magic Shop By H.G Wells

The short story titled The magic shop by H.G Wells is an interesting fiction story. This story tells a lot of unique new things. Besides the interesting things I also found moral values like: 1. The intelligent parents will understand how to protect and give everything what their son need. 2. Always listen to exprert. They will tell You what can't be done and why then do it. 3. Every human being has a mind that can develop imagination even sometimes beyond reason. By: Febiana Kusumastuti/183211047

B. 24

SYAHRUL MUKAROM 183211051 b.24 My opinion about the story is short tittle and very simple, but difficult to understanding it. I don’t know about a reason of the author to give tittle “b24”. This is make the reader ask about it, and make the story very interesting. The reader must know that we can take many moral messages from the story. About the law, injustice, and the rich. The parcipants of the story are Thief as suspected, Lady Mannering as a murderer, lord mannering as victim, and judge.       About the thief, although he was thief  because he have one reason and direction to do it. To continue he life, he have not the work that time. He just thief not the other.      At the assembly the thief tell about the event step by step, one by one, but no one was listened and the judge not believed about explanation him, still to accused that murderer is him.      From the story we must know about injustice from the law. “blunt above,...

The Moral Values of RIP Van Winkle By : Washington Irving The moral values that I have seen from 'Rip Van Winkle story is that time goes on and things keep changing whether a person is there or not. In the story, Rip takes a 21 year nap, but time does not stop the world keeps changing. Even though Rip is not aware of all of the changes going on, its still happen. When he awakes, Rip finds that there are some changes that he likes. For example, when he was going to the place where there had been a school and asked the crowd that had gathered and somebody said that everything had changed and finally he found his daughter. There were also some changes he didn't like, such as his dog getting older and his children growing up although Rip Van Winkle had been upset because he missed many important events. So the moral of the story is time does not wait the world will keep moving forward and changing . These things will happen even if someone is not ready for them! Ot...
