Thread: Wave transformation

Some electronics converts sine wave sound waves to cosine waves. I have been thinking this is a phase shift process, now I feel it isn't since the resultant waves are differently shaped. Is this any correct term for this process? I have done quite a lot computer programming doing things with sound files.

Are you talking about converting a pure tone from sin to cosine? Then that is a phase shift, alternativly it is a time delay.

Are you talking about something more complicated?

There are only 2 or 3 wavelengths I deal with. Each wave is changed from a sine wave to a cosine wave so the result will not sound the same and there is not a time delay.

I am correct in thinking there is a +90 phase shift?
