I am sure that you have used YouTube to MP3
converters at least once to get the audio file of your favorite YouTube video.
Obviously you would like to get the best quality MP3 files. But are you aware
of the role of bit rate selection when converting YouTube videos to MP3? As the
years passed, technology helped in improving the speed and quality of various
things. While this increase in speed and quality has a number of factors, a lot
of it relates to something called bit rate.
What is Bit Rate?
You must have come across the term bit rate
quite often when trying to convert YouTube videos to MP3. Bit rate is used to
describe the amount of data that is passed or processed in a specific duration.
In the context of audio / video files, bit rate refers to the amount of data
stored for each second of media that is played. Common measurements of bit rate
includes kbit/s (kilobits per second) and Mbps (megabits per second). In the
case of bit rates, the higher the value, the greater would be the quality of the
data. However, a higher bit rate would also mean greater load on the file which
may put more strain on your system as compared to a file with lower bit rate.
This is why it is important to select the most optimum bit rate value when
converting video files to audio files.

Google recommends that videos be uploaded
with a higher bit rate. This gives the compression software greater quality data
to work with. This is useful for ensuring the retention of the maximum possible
quality in the output files. When working with really high resolution videos,
it is suggested that you use a computer with i5 or i7 processor for best
results.

for videos. Since YouTube is a product of Google, the rates are applicable to YouTube
videos as well.

Significance
of Bit Rate Selection
The significance of bit rate selection is
actually more in the video upload phase rather than the conversion or download
phase. Lower bit rates means the data is compressed more which is done by
removing chunks from the data bundle. As such, you're more likely to notice
certain imperfections that come with compressing music into lower bit rate files.
A 320 kbps audio file is good enough unless you have a strict preference for
audio quality. In such cases, it would be better for you to get lossless
versions of the files. “Lossless” versions are nothing but original files which
have never been altered or compressed in any manner.
The reasons why people prefer “lossy” or
compressed formats is that they take almost a third of the space required by
lossless files. For example, an album in MP3 or AAC format might take up 100 MB
of space, whereas the same album in lossless format (FLAC or ALAC) might take
up close to 300 MB. This is the reason behind the increasing popularity of
lossy formats as it saves up on storage space and also reduces data consumption
while downloading the required files.
So the next time you plan to convert
YouTube videos to MP3, take a close look at the bit rate options and make sure
you get the one with the right bit rate. This would ensure better audio quality
and an enjoyable acoustic experience for you as you enjoy your favorite audio.
