# Definition of DSP Terms

can someone define/explain briefly (or with some detail-> up to you) the following terms:

1. Block Processing? and what are the differences between it and Sample Processing?
2. (removed)
3. What is a 3D Audio System and what is relation between it & Head Related Transfer Function (HRTF)? and how can HRTF be applied in Headphones?
4. (removed)
5. The relationship between bit rate, sample rate and bit depth? Is there a formula that combines all terms?
• wow!! good questions! – robert bristow-johnson Feb 5 '19 at 23:14
• ok but points 3 and 4 can hardly be brief... – Fat32 Feb 5 '19 at 23:30
• Welcome to DSP.se Leo.! I think this post would have deserved separate questions. – anpar Feb 6 '19 at 7:58

• @Leo let's actually NOT do that. Usually, we try to maintain a one-question-per-post ratio, so that we don't end up in this situation. rbj has given an excellent answer to most of your questions. If anyone, he'd be deserving of your acceptance of his answer. I propose the following: I'm not sure what L* means, but I'd simply edit your question to replace these two bullet points (2. and 4.) with --- and ask them, separately, in two new questions here (add a link to these new questions to your question here). That way, you can still get answers, whilst being able to accept this answer. – Marcus Müller Feb 6 '19 at 7:10
• the L* was just a place holder. i'll try to get back to HTRF later. but it really is a good idea to split multiple questions into separate questions. – robert bristow-johnson Feb 6 '19 at 19:57
• If we all agree on this, I'll edit @Leo's question and rbj's answer to exclude 2 and 4. (I'll simply add (removed) in place to not disturb the counting) – Marcus Müller Feb 12 '19 at 11:59
