Digital Audio: Part 9 - Representing DataMarch 18th 2021 - 09:00 AM

The advantages of digital audio for recording purposes are clear, but once in the digital domain, productions steps also need to be carried out. Recorders don’t care about the encoding method, which is instead optimized for production purposes.

Digital Audio: Part 8 - Sampling RatesFebruary 16th 2021 - 09:00 AM

The best sampling rate for digital audio is easily established by considering the requirements of the human auditory system (HAS), which is the only meaningful arbiter. Provided that the bandwidth of a digital audio system somewhat exceeds the bandwidth of the HAS, that should be enough.
