Technically, files have to comply with high-resolution sample rate and bit depth requirements, but the most important aspect is peak level. As the tendency in contemporary digital music production is to go for super loud masters, distortion is created as a by-product of extreme use of digital peak limiters pushing up the level. Even though the file\u2019s maximum peak level is not exceeding 0.0 dBFS, digital overshoots will still occur when the file is de-compressed back to PCM format for playback. Apple\u2019s Mastered for iTunes\u00ae criteria states that no clipping at or over 0.0dBFS should be present in the digital master to be submitted. When checked with Apple\u2019s tools specifically made for this purpose, masters with digital overs may be rejected.<\/p>\n
This is where the new Digital Delivery Mastering option for Lurssen Mastering Console comes in. It offers an additional layer of protection against peak overshoots that could be generated by the AAC compression and decompression process. This can cause clips that may go unnoticed while mixing and mastering with regular sample peak meters. This is achieved by the peak limiter at the end of the mastering chain working in a specific way. This guarantees that the compressed file is safe from distortion when played back from digital distribution services such as Apple\u2019s iTunes\u00ae, Spotify and Pandora.<\/p>\n
The Digital Delivery Mastering option is part of the HD Engine in-app purchase, and can be enabled independently from the HD Engine in the settings menu. It is also included in the free update for Mac\/PC users.<\/p>\n
Note: Please be aware that under certain extreme circumstances such as an unbalanced high frequency content of the audio file or an overly loud and distorted master due to an improper use of the application\u2019s gain staging could make for digital overshoots that may not be avoided by the DDM algorithm.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
