Marcus,

I would presently favor keeping AudioBuffer since it includes useful descriptive info and since people have already written code to handle it. Even if the descriptive info is redundant (and I’m not sure it is) we may want to add other attributes in the future, and an array of arrays will not afford that opportunity for extension.

It seems to me that getChannelData() simply becomes a trivial operation and that we remove the verbiage about “acquiring contents of an AudioBuffer” from the spec. The copy() methods can be deprecated but do not need to be broken.

I might have missed some point of discussion in the past, please correct me if I have.

…Joe
