Bit rate and audio quality
Audio and video quality
We know that there are two types of compression, called lossy, which discards information to make the file smaller, and lossless, which simply uses zip-type compression to reduce the size.
The quality of the audio depends on the number of bits that can be transmitted per second.
Let’s understand this concept well, it’s simple.
If the audio file has a certain amount of information and we can transmit ALL of it, then we will obtain a very high quality and there will be no loss of information.
On the other hand, if we must discard more data because we can only transmit a small amount, quality will necessarily be lost.
For this reason, the amount of information collected by the sample rate and the number of bits that can be transmitted per second go hand in hand. It will be useless to have a very good samplerate if the bitrate is low and forces us to transmit only a small portion of the abundant data available.
Many times when encoding a file, of any format, information is lost either by using a poor encoder or by mutilating the wrong settings.
Mp4Gain is highly efficient at all of this and uses the best settings for you to get the best quality, both when encoding and converting.
