I want to know the answer to the following question:
Where were most of the authors in the JSAC edition?
All the background I'm provided with is that "While there were some papers from before that time, this collection documented an entire variety of finished, working audio coders, nearly all of them using perceptual (i.e. masking) techniques and some kind of frequency analysis and back-end noiseless coding.". Is that enough to answer the question?
Answer: no
