New sample for Cloud generator
Sorry all, it's been a while since I've posted anything new, I've been rather busy with my new job, and am currently in Hollywood Florida, so it's been a bit of a change for me :-)
Anyway, I'm pleased to let you know that there is a new sample for the new prototype cloud generator module to enjoy.
Click here to listen to it.
So what is it that you are listening to? Well, here is what Paul Schreiber wrote about it, it's done on the new audio engine hardware he is currently developing with:
As usual, square-waves in the left channel, sine waves in the right.
This lashup uses the Xilinx S3Esk development board and the Analog Devices ADuC7020 Mini-kit demo system. The two are connected through a 3-wire SPI interface running at ~500kHz clock rate, which means we only get the oscillator frequencies updated at about a 100Hz rate. The ARM reads two voltages and interprets them as frequency and spread. From this it computes 16 oscillator frequencies and sends these to the FPGA. The voltages are just 2 pots, so the demo is just "knob twisting". But you can hear the various effects of the raw oscillators (no chaos or PWM or spectral shaping).
The ARM we will actually use is the 7026, which has more ROM/RAM but uses the same 'core'.
There, that's the low down :-)
