Jaka will explore a little about the meaning of audio files in depth and important terms in audio files where this can optimize audio quality when you hear music later.
Everyone knows what it is Audio files or what we usually call music files, but not everyone knows about this technology in depth. It looks trivial or not important for you to learn more. But this knowledge is very useful for those of you who want to make music recordings or just maximize the audio quality when you listen to yourself.
Therefore, ApkVenue will explore a little about the meaning of audio files in depth where this can also optimize audio quality when you hear music later. Here are 5 important terms in audio files that you must know.

5 Important Terms in Audio Files You Must Know
1. Sample Rate
Source: makeuseof.com How does an audio device work while recording? The device works by capturing sound waves periodically or picking up from time to time.Snapshots'. Where is every snapshot called Sample and the interval that each snapshot uses is called Sample Rate. The shorter the interval, the faster the frequency, if the frequency is faster, the audio quality will be more accurate.
2. Bitrate
Source: wikipedia.org Many people think that Bitrate together with Sample Rate, but they have a fundamental difference. Bitrate is the amount of voice data processed per second, and it is usually multiplied by the sample rate by the bit depth. For example, an audio file with a sample rate of 44.1 Khz and a depth of 16 bits will have a Bitrate of 705.6 Kbps. So if the bit depth is higher, the recording results will also be better and better.
3. Stereo vs Mono
Source: audacityteam.org Many people still don't understand the difference between Stereo and Mono. In short is Mono means one channel while Stereo means two channels. The two channels in Stereo can be referred to as 'Left' and 'Right'. So if you listen to stereo type music with headphones then you will hear two different sounds between Left and Right. But it will be very different if you listen to Mono type files, you will only hear flat music.
Stereo type audio files also have more memory than Mono type files. So if you are planning to reduce the audio file size significantly then converting Stereo music to Mono is the right step. But at your own risk, because your music will sound flat later.
4. Compression
Source: techeye.net Compression you can call compression or commonly referred to as reducing the size of a file. If you want to shrink an audio file then you can play around by changing settings like Sample Rate, Bitrate, and Stereo, and Mono.
There are 2 ways to compress audio files, namely:
- Lossy compression is by eliminating unnecessary data in audio files, such as distant voices. But the data will be completely lost after being compressed.
- Lossless compression is to compress all audio files using mathematical algorithms. But the audio file must be decompressed again while playing so it will require more power when the audio is played later. The advantage is that no audio data is lost
5. File Format

The following is a brief explanation of the differences between the three file types:
- MP3 is the most popular audio file because MP3 is the first audio file type to appear.
- ACC technically ACC has advantages compared to MP3 but rarely uses the file because it has a larger memory than MP3.
- OGG also good, but not many devices support the OGG file type.
By knowing the 5 things above, then you can now make audio recordings with the desired quality. You can also compress audio files properly without destroying the quality of the audio file.
