MP4 BITRATE CONVERTER MP3 SONG

For instance, to achieve the same quality, MP3 song needs to be encoded around 192Kbps, while the M4A song is enough with 128Kbps, meaning that it takes smaller file size.Ĭompatibility: Undoubtedly, MP3 still dominates the audio industry. When the bitrate increases, the sound quality will increase as well and so does the file size. And even for M4A audio encoded with AAC lossy compression, the test indicates that it still performs in better sound quality than MP3 files coded at the same bitrate, particularly when bitrate is at or below 128Kbps.įile Size: The file size and quality is directly related to the bitrate. Quality: For obvious reasons, an M4A file with ALAC compression has the best quality since none of the original sound signal will be lost. For more details, refer to the below comparison. Generally, no matter what unit being used, the higher number, the higher speed or higher quality.) If you’re faimilar with music encoding, it is recommended to save M4A music at 192kbps and we can get both great quality and small file size. The common measurement of bitrate is kbit/s and Mbps, respectively meaning kilobits per second and megabits per second. (PS: Bitrate refers to the amount of data that is being transmitted within a given amount of time along a digital network. M4A format files typically have stereo bitrate of 128kbps, 192 kbps or 256kbps. MP3Īctually M4A is generally taken as the successor to MP3 because it does the same thing as MP3 but comparing with MP3, M4A could compress audio with the same bitrate in smaller file size. But the poor compatibility with other devices makes M4A audio playback rather inconvenient as compared with MP3 files. Also good is that M4A audio file does not have Digital Rights Management (DRM) protection so it can be edited and transferred more flexibly.Ĭons: M4A can be well recognized in iTunes, iPod and other Apple devices. Pros: The M4A file is compressed but the quality is lossless.

It is a codec designed to provide lossless encoding in less storage space.

M4A music can be directly set as iPhone ringtone by renaming the file extension from M4A to M4R with iTunes.

iTunes store also provides music in other formats other than M4A.Most M4A songs on iTunes Store come with a price but there’re also special offers or giveaway sometimes.M4A audio can be decoded back to the original quality before they were compressed.Protected files usually have M4P file extension.
