Description (last modified by bennylp)
Issues with the tone generator:
- The sine approximation algorithm especially for the fixed point version is not good enough, causing aliasing frequencies to occur
- The volume perhaps can be made louder
- The volume is different between float and fixed point version
- The tonegen should attempt to create a full period of wave signal, slightly truncating or appending some samples as necessary.
