With the increasing speed of todays desktop computer systems, a growing number of computationally intense tasks such as computing the Fourier transform of a sampled audio signal have become available to a broad base of users. Being a process traditionally implemented on dedicated DSP systems or rather powerful computers only available to a limited number of people, the Fourier transform can today be computed in real time on almost all average computer systems. Continue reading…

If you’re into signal processing, you will no doubt say that the headline is a very tall claim. I would second this. Of course you can’t learn all the bells and whistles of the Fourier transform in one day without practising and repeating and eventually delving into the maths. However, this online course will provide you with the basic knowledge of how the Fourier transform works, why it works and why it can be very simple to comprehend when we’re using a somewhat unconventional approach.

September 21st, 1999 — Finally finished and uploaded the two articles “The DFT à Pied” and “Pitch Shifting Using The Fourier Transform”. Did some other minor corrections regarding the Meta tags of the pages.

September 13rd, 1999 — Upgraded DSP Dimension to provide a higher transfer volume due to the immense interest. October alone had 114 MB download of web content (not counting audio) which is overwhelming considering the pages occupied a little over 700kB at that time.

September 9th, 1999 — Fixed some typos on the formant tutorial page
