#Mp3 to m4a converter 320 kbps mp4#
It was developed by Apple and it only contains audio data, rather than MP4 which contains both audio and video. This effectively means that they can be decoded back to their original quality they were at the point of compression. M4A is a file encoded with advanced audio coding (AAC) and is implemented with AAC compression standards or ALAC (Apple Lossless Audio Codec) specifications. It's the default audio format for Apple products, Nintendo products, Android, Blackberry, PlayStation, and many in-dash music systems in cars. M4A files sound better than MP3 files when encoded at the same bit rate due to some of the enhancements. It was generally intended as the successor to MP3 and the file quality is better and file sizes smaller compared to MP3 files. M4A audio files were developed to enable easy sharing of digital music, audiobook content, podcasts.
The difference is massive and so are the download times. RAW file formats generally require 176,000 bytes per second compared to a lossy format which requires 17,600. By using lossy formats it enables even dial up users to download mp3 files at a reasonable speed. The reason lossy formats are used over RAW is that RAW audio files are too large to travel over the internet at any great speed. In other words, that means it removes the information that your ear doesn't notice thereby making the file smaller. Instead, MP3 files use perceptual coding. That means that an MP3 file does not contain 100% of the original audio information. This then enables you to get hundreds of songs on to a CD and it also has opened up a new market over the internet - the download market as download times have been significantly reduced. MP3 gets rid of a lot of the information recorded in a song that our ears are not able to hear and then uses complex algorithms to reduce the file size. This converter cannot support encrypted or protected audio files. Remark: If file upload process takes a very long time or no response or very slow, please try to cancel then submit again. Once upload completed, converter will redirect a web page to show the conversion result. MP3 is a digital music format which allows CD tracks to be reduced to around a tenth of their normal size without a significant loss of quality. Click button 'Convert' to start upload your file.
