A sawtooth contains a fundamental frequency and odd+even harmonics (frequencies that are an integer multiple of the fundamental). So it does contain more than one frequency. But yes - it is conventional to say "A 100Hz sawtooth", which really means that its fundamental is 100Hz. | |

Sure, you can Fourier-analyse any signal and get a whole bunch of frequencies, but that's not the only useful definition. Ab initio, frequency is just the inverse periodic duration of a signal, which is a single well-defined value no matter if you have a sine or sawtooth wave. — Of course, then it's still not clear what "changing the frequency" means. | |

| Nov 28, 2013 at 5:37 | comment | added | Sathyaish | Okay, I just got to know you've been doing this since you were young and that you've written a book on mixing audio called Mixing Audio. I also searched some more and found that for someone like me who wants to understand the basics of sound, here is a good book: amazon.com/Sound-Reinforcement-Handbook-Yamaha-Products/dp/… | |
| Nov 28, 2013 at 5:19 | comment | added | Sathyaish | Thank you, @Izhaki. Can you tell me how you learnt all this? What's a good place to start? Is there a book that you found very useful? | |
| Nov 28, 2013 at 1:46 | comment | added | Izhaki | To be technically correct - only sine waves are made of a single frequency; all other sounds are made of more than one. Thus, you can't really 'increase' the frequency of a sound wave. You pitch-shift it. | |
