A few days ago I was in a class about electronics on my study. The first lesson was an introduction into the main subject, bits, analog signals, conversion, etc. An example was asked by the teacher: What is the maximum feasible amount of bits to store audio information in?
Some of the answers that were thrown through the class included "64bit, 32bit, 16bit, 8bit (yeah I know..)…".
then the teacher said it's about 18,19 bits, then you are reaching the upper limit because distortions, noise, etc begin to play a big role for audio recordings.
I do know the typical DVD/Studio quality is 24bit audio.
However this led me thinking: What is the maximum physical/real/electronic bitsize in which a piece of audio can be stored? would 32bit audio be overkill/contain too much noise?
Any explanation/sources on this?
