Hello:
I am creating an audio app, it makes different waves. Trying different things with Wavosaur I got this surprise:
If I create a sine wave (let's say 1000hz and 16 bits) in wavosaur and do the spectrum analysis, u see a beatiful sine. If u save this to file, open it and do the same spectrum analysis you see the noise spread in all higher frequecies.
Then I don't know what wavosaur exactly does. The first analysis is so perfect that is very theorical since it doesn't add dither but has cero noise nor even cuantization noise in the higher frecuencies.
What is wavosaur doing that gives u a different spectrum analysis once saved and opened the file?
Thanks in advance. |
