Subject: Automated Audio Testing
A good question is what should we test?
- Clipping
- Noisieness
- Similarity to other sounds
- Matching chunks?
- Zero Crossings?
- Amplitude
- Spectral Components
- Pitch
- Impulses
These are just a few.
Subject: Automated Audio Testing
I have this idea for automated audio testing. The idea is that when one
programs they should unit test as they go. If a person is using XP then
they probably want to use the "Test First" methodology. Of course "Test
First" has its problems. GUIs are very hard to test, so is anything that
relies on multiple processes or multimedia.
Audio programming is interesting as the data produced (audio) can be tested but often cannot be compared. Randomization in units or differences in timing between processes can result in two audiofiles which can sound the same but simply not comparable using string comparison.
Thus I wanted to make a system to allow you to use test first methodologies when programming audio. It became apparent I'd have to be language agnostic for anyone to use the system since a lot of the things being tested might be written in a synthesis package and not a classical language like java, C, C++, etc.
