Apple is working on a new audio file format that would allow it to deliver high- or low-quality files to iCloud users based on bandwidth. Citing a source with inside knowledge of the process, the Guardian reports that the new system would adjust itself to the bandwidth and storage available on the receiving device, and would be used to enhance the company’s iTunes Match service.
According to the report, Apple has already asked a London studio to prepare audio files for the new streaming format. “All of a sudden, all your audio from iTunes is in HD rather than AAC.
Users wouldn’t have to touch a thing – their library will improve in an instant,” said the source. Apple has recently been encouraging submission of audio files in the 24-bit/96KHz standard, and has also released a set of guidelines for mastering to iTunes which hint at a such a possible future service: “As technology advances and bandwidth, storage, battery life, and processor power increase, keeping the highest quality masters available in our systems allows for full advantage of future improvements to your music.
