Now that you understand what music file compression is, are you wondering how each file format is compressed?<\/p>\n
<\/p>\n
Let’s talk about the compression method for each file.<\/p>\n
How to compress each file format
\nuncompressed format
\nUncompressed files are, of course, completely uncompressed. The most commonly used uncompressed file formats are WAV or AIFF.<\/p>\n
These formats are the type of format that is often used when exporting files from your DAW. If you duplicate a track with WAV, the duplicate WAV file will be a copy of the original sound.<\/p>\n
lossless compression
\nAlthough lossless files are compressed, they are only compressed as WAV and retain the original amount of information. Lossless files are only decompressed when you open the file.<\/p>\n
The most common lossless format is FLAC. Apple also has its own format called ALAC, so if you have a relationship with iTunes, you’ll probably use ALAC.<\/p>\n
FLAC makes the file size smaller than WAV and preserves the original amount of information, but the file size still tends to be large.<\/p>\n
rose compression
\nCompressed Rossy files are probably the most widely used audio format. MP3s are the most used. However, other file formats like OGG, WMA, AAC are also included in Rossie’s compression.<\/p>\n
The downside of Rossy compression is that it causes “sound degradation” which actually occurs when the amount of information in the original data is removed.<\/p>\n
However, the advantage is that the smaller size makes loading faster and requires less space to store data.<\/p>\n
Files with lossy compression can be divided into high resolution and low resolution depending on how much they are compressed. High-quality files lose less information.<\/p>\n
The truth about bitrate
\nIt is the bit rate that determines the sound quality of audio files.<\/p>\n
The bit rate indicates the amount of data processed per second. In the case of MP3, it is the part that is displayed as 320 or 192. In other words, the larger the size, the greater the amount of data packed and the better the sound quality. By the way, how to calculate the bitrate for sound quality:<\/p>\n
Sampling rate (Hz) x bit depth (bit) = bit rate (bps)<\/p>\n
* Is the sample rate divided into tens of thousands per second to sample the sound? Bit depth is the amount of data per divided sample.<\/p>\n
For example, an MP3 file with a bit rate of 320 has a data volume of 320 kilobits (320 kbps for short) per second.<\/p>\n
Uncompressed WAV and AIFF files are typically 1411 kbps.<\/p>\n
Increasing the bit rate means that more data is processed per second. The more data you have, the better the sound. Don’t you think it’s very simple?<\/p>\n
Now, did you understand the basics of compression, file format, and bitrate? Let’s continue.<\/p>\n
The following is a question that is easy to catch fire.<\/p>\n
What is the best way to use each file format?
\nIf we were to cover all audio formats, it would take hours to finish reading. Readers have their own things to do and make music, right?<\/p>\n
So the answer is simple, and I will list only three commonly used file formats. It is WAV, MP3 320kbps, MP3 192kbps.<\/p>\n","protected":false},"excerpt":{"rendered":"
