I found a software the says 'bitrate changer'. What it does is it changes the bitrate and the mp3 file increases in size to almost 3 times the original size in bytes. The quality of the MP3 remains the same, so I don't see the use of it. Does anyone know what is the benefit of doing this?
What is the use of changing the bitrate of a mp3 file?
Only noticable effect is if you change it like a 6kbs bitrate, music sounds like a dead parrot, and file size is tiny, But higher than 192kps, it doesnt change sound quality on file size
What is the use of changing the bitrate of a mp3 file?
There are absolutely times when some people need to change the bit rate. If you have a player in a car for example that will only play 128Kbp and your copy is 192Kbp or CD format. Yes 6kbps would sound more like a dying parrot but if your a non-profit organization that wants to put a lot of half hour long voice programs on the internet and has to pay for the bandwidth they will want to cut it in half by changing to mono and then reducing it to 28Kbps. Yes Pastor Jack * may sound like he's got his head in the toilet but people can still hear it good enough and be able to even if they only have dial-up.
You can have variable bit rates too so you can maximize the sound quality where needed and reduce it where the material is less demanding but that gets more complicated.
bitrate changers are generally used to shrink the memory size of an mp3 file, not the other way around. it doesn't work the opposite way, or to augment the quality of the file by adding more memory size. yes, you can change the bitrate alright, but the quality will not change because the original file can only provide the same information it already has and the software could not add furthermore from that except for information that do not serve anything to the quality of the file. whereas, if you use the software to shrink the memory size, it merely compresses furthermore the original file, i.e. trim some information from the original file, to convert it to a smaller file and lesser quality. simply, you cannot put in more water to a glass that's already full.
You should trash the software unless you want to compress the song even further - increasing the bit rate can never bring back what has already been lost due to the compression format, in simple terms an MP3 can never be made better on its own, you need a much better uncompressed source of audio to get higher quality.
