Furthermore, LPCM(Linear pulse code modulation) is the most common, uncompressed audio format in this, but it can also store compressed audio like MP3. Also, it is especially used by professionals as LPCM audio format offers a maximum quality. Only files up to 4 GB are supported by this format which is one of the limitations in this format. This is because of 32-bit unsigned integer which carries the file size header. To overcome this, W64 format came into existence which can record long audios as it enables 64-bit header. |
