Default Variable cd pitch by changing clock speed


Variable clock speed controls during either playback or recording allows
the speed of conversion to be altered to control tempo. To vary pitch
you need to play with the audio waveform in real-time. Frequency
conversion up/down allows the pitch to be altered. Use both and you can
have Frank singing My Way in Mickey's voice with the song playing at the
original speed. Or you can have Franks voice stretching the song out a
couple minutes. Take a loot at a modern mixer panel and you will find
lot's of toys to "shape" the tone and tempo of the inputs and allow
everything to work.

Even a SoundBlaster card has the parts and software to handle it. Take a
look at the environmental sound adjustments sometime.

Both are independent for any other use. It is very easy to sped up a
song while keeping the pitch the same or to vary the pitch at the

same
speed setting. If it wasn't over half of today's "artists" would be

out
of work due to singing off key and off tempo.

Would you elaborate on how easy it is to accomplish, please?
